The heart of this circuit is the LM3914 from Texas Instruments (formerly National Semiconductor). The LM3914 can sense voltage levels and drive a display of 10 LEDs in dot mode or bar mode. The bar mode and dot mode can be externally set, and multiple ICs can be cascaded together to create an extended display. The IC can operate from a wide supply voltage range (3V to 25V DC). The brightness of the LEDs can be programmed using an external resistor. The LED outputs of the LM3914 are TTL and CMOS compatible, making it versatile for various digital applications.DescriptionIn the circuit diagram, LEDs D1 to D10 display the battery level in either dot or bar graph mode. Resistor R4, connected between pins 6 and 7 and ground, controls the brightness of the LEDs. The typical value for R4 is between 1kΩ to 10kΩ, depending on the desired LED brightness and current consumption. Resistors R1 and potentiometer R2 form a voltage divider network, and POT R2 can be used for precise calibration of the voltage thresholds.The circuit shown here is designed to monitor voltage levels between 10.5V and 15V DC, making it ideal for 12V lead-acid or lithium-ion battery systems. The calibration procedure is as follows: After assembling the circuit, connect a stable 12V DC source to the input. Adjust the 10K potentiometer (R2) until LED10 glows (in dot mode) or all LEDs up to LED10 illuminate (in bar mode). Now decrease the voltage in steps, and at 10.5 volts, only LED1 should glow. Switch S1 selects between dot mode and bar graph mode. When S1 is closed, pin 9 of the IC connects to the positive supply, enabling bar graph mode. When switch S1 is open, pin 9 disconnects from the positive supply, and the display operates in dot mode.With minor modifications, the circuit can monitor other voltage ranges. To adapt the circuit, remove resistor R3 and connect the upper level voltage to the input. Adjust potentiometer R2 until LED10 glows (in dot mode). Remove the upper voltage level and connect the lower voltage level to the input. Install a high-value potentiometer (such as 500kΩ) in place of R3 and adjust it until only LED1 glows. Remove the potentiometer, measure its resistance, and install a fixed resistor of the same value in place of R3. Your customized voltage level monitor is now ready.Circuit Diagram of Battery Level Indicator Using LM3914Cascading Two LM3914 ICsTwo or more LM3914 ICs can be cascaded together to create an extended display with more resolution. The schematic of two LM3914 ICs cascaded together to create a 20-LED voltage level indicator is shown below. This configuration is particularly useful for applications requiring finer voltage resolution or monitoring wider voltage ranges. When cascading, connect pin 11 (REF OUT) of the first IC to pin 6 (RHI) of the second IC, and ensure both ICs share common ground and power supply connections.Key Component SpecificationsThe LM3914 features a built-in voltage reference of 1.25V (±5% tolerance) and can drive LEDs with up to 30mA per output. The IC includes internal current limiting, but external current-limiting resistors are recommended for optimal LED protection and brightness control. The operating temperature range is 0°C to +70°C for commercial grade versions.Alternative Battery Level Monitoring Circuits1. Simple Battery Level Indicator: This circuit can be used for monitoring 3V batteries. Modern alternatives include circuits based on voltage comparators like the LM339 or microcontroller-based solutions using ADC inputs for more precise monitoring.2. 3-LED Battery Level Indicator: A 3-LED battery level indicator suitable for monitoring 12V automotive batteries. This simple circuit displays three battery states: below 11.5V (discharged), between 11.5V and 13.5V (normal), and above 13.5V (charging). This design uses comparators or voltage dividers with transistor switches.3. Flashing Battery Monitor: This circuit monitors 6V to 12V batteries using discrete transistors. The voltage threshold at which the LED starts flashing can be adjusted using a potentiometer, providing a visual low-battery warning.4. Modern Digital Alternatives: Contemporary designs often use microcontrollers (such as Arduino, ESP32, or STM32) with built-in ADCs for more accurate voltage monitoring, data logging capabilities, and the ability to display information on LCD or OLED screens. These solutions offer greater flexibility and can monitor multiple parameters simultaneously.Practical ApplicationsThis LM3914-based battery level indicator is ideal for various applications including:Automotive battery monitoring systemsSolar power system voltage monitoringUPS (Uninterruptible Power Supply) status displaysPortable power bank indicatorsMarine battery monitoringRV and camping equipment power managementElectric vehicle battery status displaysFrequently Asked Questions (FAQs)Q1: Can I use the LM3914 with lithium-ion batteries?Yes, the LM3914 can be used with lithium-ion batteries. However, you'll need to adjust the voltage divider network (R1, R2, R3) to match the voltage range of your specific lithium-ion battery (typically 3.0V to 4.2V per cell). For a 3S lithium-ion pack (9V to 12.6V), the circuit can be calibrated accordingly.Q2: What is the difference between dot mode and bar mode?In dot mode, only one LED corresponding to the current voltage level illuminates. In bar mode, all LEDs from LED1 up to the current voltage level illuminate, creating a bar graph effect. Bar mode provides a more intuitive visual representation of the battery level, while dot mode consumes less power.Q3: How much current does the LM3914 circuit consume?The LM3914 IC itself consumes approximately 1-4mA in standby. LED current consumption depends on the brightness setting (controlled by R4) and the mode selected. In dot mode with one LED lit at 10mA, total consumption is around 11-14mA. In bar mode with all 10 LEDs lit, consumption can reach 100-104mA.Q4: Can I cascade more than two LM3914 ICs?Yes, you can cascade multiple LM3914 ICs to create displays with 30, 40, or more LEDs. Each additional IC adds 10 more LED segments. Ensure proper voltage reference cascading and adequate power supply capacity for all ICs and LEDs.Q5: Is the LM3914 still available for purchase in 2025?Yes, the LM3914 remains available from Texas Instruments and various distributors, though it's considered a legacy product. Alternative ICs with similar functionality include the LM3915 (logarithmic scale) and LM3916 (VU meter scale). For new designs, consider modern alternatives or microcontroller-based solutions for enhanced features.Q6: What type of LEDs should I use with this circuit?Standard 5mm or 3mm LEDs work well with this circuit. Red, green, yellow, or multi-color LEDs can be used. For bar graph displays, specialized 10-segment LED bar graph modules are available. Ensure the LED forward voltage is compatible with your supply voltage, and adjust R4 accordingly for optimal brightness.Q7: How accurate is the LM3914 voltage measurement?The LM3914's internal voltage reference has a typical accuracy of ±5%. Overall circuit accuracy depends on the tolerance of external resistors and proper calibration. Using 1% tolerance resistors and careful calibration can achieve accuracy within ±2-3% of the full-scale voltage range.Q8: Can this circuit be used with AC voltage?No, the LM3914 is designed for DC voltage monitoring only. To monitor AC voltage, you would need to add a rectifier circuit (bridge rectifier with filtering capacitors) to convert AC to DC before connecting to the LM3914 input. Ensure proper isolation and safety measures when working with AC mains voltage.Note: Always observe proper safety precautions when working with batteries and electrical circuits. Ensure adequate heat dissipation for the LM3914 IC, especially in bar mode with all LEDs illuminated.Original content produced by circuitstodayArticle Update Information: This article was originally published in 2021 and has been updated in November 2025 to reflect current component availability, correct outdated manufacturer information (National Semiconductor is now part of Texas Instruments), improve technical accuracy, add practical applications, and include comprehensive FAQs.

 Inside a secretive AI nonprofit backed by Elon Musk and other Silicon Valley figures, a handful of robots designed to help out in warehouses are gradually learning how to do useful household chores.OpenAI, which was created to do basic AI research, is reprogramming robots developed by Fetch Robotics, a company that supplies warehouse automation hardware. Researchers at OpenAI are equipping the robots with software that lets them train themselves through trial and error.The effort reflects a bet that innovations in software and machine learning, rather than breakthroughs in hardware, are the way to give robotics remarkable new capabilities. Fetch makes a range of robots for warehouses, including systems that follow workers around a building, carrying items dropped into a basket. OpenAI is using a system that features a mobile base but also 3-D depth sensors, a 2-D laser scanner, and a robotic arm with seven degrees of freedom.In April, OpenAI recruited Pieter Abbeel, a professor at the University of California, Berkeley, and a leading expert on robot learning. Abbeel has shown how robots can use a machine-learning approach called deep reinforcement learning to acquire completely new skills that would be hard to program by hand, such as folding towels or retrieving items from a refrigerator. Google DeepMind, an AI subsidiary based in the U.K., uses this technique to get computers to play computer games at a superhuman level.Abbeel’s robots learn tasks from scratch, using a neural network that receives sensor input and controls physical movement. The network adjusts its parameters automatically as it inches closer to its goal. A robot might try thousands of grips, for instance, in the process of learning how to hold a certain object.“If this goal can be achieved, then there will be economic and industrial benefits,” says Marc Deisenroth, an expert on reinforcement learning at Imperial College London. “Imagine a Roomba not only cleaning your floor but also doing the dishes, ironing the shirts, cleaning the windows, preparing breakfast.”Deisenroth says using off-the-shelf robots could drive costs down. “Currently, the software seems to be the bottleneck,” he adds. “However, independent of this, better hardware could also lead to substantial improvements.” Soft manipulators and elastic feet similar to a monkey’s feet are concepts that researchers have started working on, he says.Some manufacturers, including the Japanese company Fanuc, are testing reinforcement learning as a way to train industrial robots quickly in new tasks such as learning to grasp unfamiliar objects. When many robots work in parallel, the training time required is reduced accordingly . Robot researchers at Google are testing similar learning techniques.“Moving away from having to program robots by hand by endowing robots to learn autonomously is a key element for the future of robotics,” says Jens Kober, an expert on robot learning at Delft University of Technology in the Netherlands. Kober says having robots share the information they have learned will be crucial.While robots such as those made by Fetch are finding their way into many factories and warehouses, domestic robot helpers remain the stuff of science fiction. Performing seemingly simple tasks like washing dishes or folding laundry in a messy home setting is incredibly hard for a machine. A robot programmed the conventional way can easily be thrown off by an unfamiliar object or a slight variation in lighting.OpenAI confirmed that it is working with the robots from Fetch, but it declined to comment further. Melonee Wise, the company’s founder, couldn’t be reached for comment.OpenAI was created by Musk and a handful of well-known (and well-heeled) Silicon Valley entrepreneurs, including investor Peter Thiel, Y Combinator president Sam Altman, and the incubator’s cofounder Jessica Livingston. The nonprofit’s backers have committed $1 billion in funding to the project, and it is being led by Ilya Sutskever, a prominent AI researcher who left Google to join the project, and Greg Brockman, an early employee at the high-profile digital payment company Stripe.While OpenAI has committed to making the technology it develops publicly available, it could certainly benefit companies backed by Musk and Thiel, as well as those emerging from Y Combinator.Produced by Will Knight 

Engineers at the University of California San Diego have developed a flexible wearable sensor that can accurately measure a person's blood alcohol level from sweat and transmit the data wirelessly to a laptop, smartphone or other mobile device. The device can be worn on the skin and could be used by doctors and police officers for continuous, non-invasive and real-time monitoring of blood alcohol content.The device consists of a temporary tattoo—which sticks to the skin, induces sweat and electrochemically detects the alcohol level—and a portable flexible electronic circuit board, which is connected to the tattoo by a magnet and can communicate the information to a mobile device via Bluetooth. The work, led by nanoengineering professor Joseph Wang and electrical engineering professor Patrick Mercier, both at UC San Diego, was published recently in the journal ACS Sensors."Lots of accidents on the road are caused by drunk driving. This technology provides an accurate, convenient and quick way to monitor alcohol consumption to help prevent people from driving while intoxicated," Wang said. The device could be integrated with a car's alcohol ignition interlocks, or friends could use it to check up on each other before handing over the car keys, he added."When you're out at a party or at a bar, this sensor could send alerts to your phone to let you know how much you've been drinking," said Jayoung Kim, a materials science and engineering PhD student in Wang's group and one of the paper's co-first authors.Blood alcohol concentration is the most accurate indicator of a person's alcohol level, but measuring it requires pricking a finger. Breathalyzers, which are the most commonly used devices to indirectly estimate blood alcohol concentration, are non-invasive, but they can give false readouts. For example, the alcohol level detected in a person's breath right after taking a drink would typically appear higher than that person's actual blood alcohol concentration. A person could also fool a breathalyzer into detecting a lower alcohol level by using mouthwash.Recent research has shown that blood alcohol concentration can also be estimated by measuring alcohol levels in what's called insensible sweat—perspiration that happens before it's perceived as moisture on the skin. But this measurement can be up to two hours behind the actual blood alcohol reading. On the other hand, the alcohol level in sensible sweat—the sweat that's typically seen—is a better real-time indicator of the blood alcohol concentration, but so far the systems that can measure this are neither portable nor fit for wearing on the body.Now, UC San Diego researchers have developed an alcohol sensor that's wearable, portable and could accurately monitor alcohol level in sweat within 15 minutes."What's also innovative about this technology is that the wearer doesn't need to be exercising or sweating already. The user can put on the patch and within a few minutes get a reading that's well correlated to his or her blood alcohol concentration. Such a device hasn't been available until now," Mercier said.How it worksWang and Mercier, the director and co-director, respectively, of the UC San Diego Center for Wearable Sensors, collaborated to develop the device. Wang's group fabricated the tattoo, equipped with screen-printed electrodes and a small hydrogel patch containing pilocarpine, a drug that passes through the skin and induces sweat.Mercier's group developed the printed flexible electronic circuit board that powers the tattoo and can communicate wirelessly with a mobile device. His team also developed the magnetic connector that attaches the electronic circuit board to the tattoo, as well as the device's phone app."This device can use a Bluetooth connection, which is something a breathalyzer can't do. We've found a way to make the electronics portable and wireless, which are important for practical, real-life use," said Somayeh Imani, an electrical engineering PhD student in Mercier's lab and a co-first author on the paper.The tattoo works first by releasing pilocarpine to induce sweat. Then, the sweat comes into contact with an electrode coated with alcohol oxidase, an enzyme that selectively reacts with alcohol to generate hydrogen peroxide, which is electrochemically detected. That information is sent to the electronic circuit board as electrical signals. The data are communicated wirelessly to a mobile device.Putting the tattoo to the testResearchers tested the alcohol sensor on 9 healthy volunteers who wore the tattoo on their arms before and after consuming an alcoholic beverage (either a bottle of beer or glass of red wine). The readouts accurately reflected the wearers' blood alcohol concentrations.The device also gave accurate readouts even after repeated bending and shaking. This shows that the sensor won't be affected by the wearer's movements, researchers said.As a next step, the team is developing a device that could continuously monitor alcohol levels for 24 hours. Provided by: University of California - San Diego

What is the difference between SMT and through-hole technology?SMT mounts components directly on the PCB surface, while through-hole technology inserts component leads through drilled holes. SMT offers higher density, smaller size, and automated assembly advantages, whereas through-hole provides stronger mechanical bonds for high-stress applications.2. What is the typical reflow temperature profile for lead-free soldering?A standard SAC305 lead-free profile includes: preheat zone (150-180°C for 60-120 seconds), soak zone (180-200°C for 60-90 seconds), reflow zone (peak 235-250°C for 30-60 seconds above liquidus), and cooling zone (controlled cooling to below 100°C).3. How small can SMT components be manufactured?As of 2025, the smallest mass-produced passive components are 008004 (0201 metric), measuring 0.2mm × 0.1mm. However, 01005 (0402 metric) components remain the most commonly used ultra-small size in high-volume production.4. What is the purpose of nitrogen in reflow soldering?Nitrogen atmosphere reduces oxidation during reflow, improving solder wetting, reducing defects, and enhancing joint reliability. It's particularly beneficial for lead-free soldering and fine-pitch components, though it increases operational costs.5. How is SMT quality controlled?Quality control involves multiple inspection stages: solder paste inspection (SPI) after printing, pre-reflow AOI, post-reflow AOI or 3D inspection, X-ray for hidden joints, and functional testing. Modern facilities use AI-powered systems for real-time defect detection and process optimization.6. What is the shelf life of solder paste?Refrigerated solder paste typically has a shelf life of 6-12 months at 2-10°C. After opening, it should be used within 8-24 hours at room temperature, depending on the formulation. Always follow manufacturer specifications for optimal performance.7. Can SMT and through-hole components be assembled on the same board?Yes, mixed technology assemblies are common. Typically, SMT components are placed and reflowed first, followed by through-hole component insertion and wave soldering or selective soldering. Some processes use solder paste for through-hole components as well.8. What causes component tombstoning and how can it be prevented?Tombstoning occurs when unbalanced forces during reflow cause one end of a component to lift. Prevention methods include: balanced pad design, optimized reflow profile with gradual heating, proper component placement, and equal thermal mass on both component ends.9. What is the difference between Type 3, Type 4, and Type 5 solder paste?These designations refer to powder particle size: Type 3 (25-45μm) for standard applications, Type 4 (20-38μm) for fine-pitch components down to 0.5mm, and Type 5 (15-25μm) for ultra-fine pitch below 0.4mm. Smaller particles provide better printing definition but may reduce shelf life.10. How does humidity affect SMT assembly?Moisture-sensitive components can absorb humidity, causing "popcorning" during reflow when internal moisture vaporizes rapidly. Components are rated by moisture sensitivity level (MSL 1-6), requiring dry storage and limited floor life. Baking may be necessary before assembly if exposure limits are exceeded.Future Trends and DevelopmentsEmerging TechnologiesHeterogeneous Integration: Combining different chip technologies in single packagesFlexible and Stretchable Electronics: SMT adaptation for non-rigid substratesAdvanced Thermal Management: New materials and techniques for high-power applicationsQuantum Computing Components: Specialized assembly requirementsBio-compatible Electronics: Medical implant and wearable applicationsMarket ProjectionsThe SMT equipment market is expected to reach $9.5 billion by 2030, driven by:Continued miniaturization demandsAutomotive electronics expansion (ADAS, EV systems)5G and 6G infrastructure deploymentAI hardware proliferationMedical device innovationConclusionSurface Mount Technology remains the cornerstone of modern electronics manufacturing, continuously evolving to meet the demands of increasingly complex and miniaturized electronic devices.
