L293D Pinout ConfigurationThe pin arrangement of L293D is shown in Figure 1.Pins 1A, 2A, 3A, and 4A are control signal input terminals, which are used to control the working state of the motor. The pins 1Y, 2Y, 3Y, and 4Y are motor control output terminals, which are used to directly control the actions of the motor.Figure 1 L293D pinoutAll inputs of the device are TTL compatible, and its output adopts a "totem pole" drive circuit composed of a Darlington transistor receiver and a pseudo Darlington source. The motor drive enable is controlled by pins 1 and 2EN to control motor 1, and pins 3 and 4EN to control motor 2. When the EN pin is set to high level, the motor corresponding to it is in the enabled state, thereby activating the motor control output. The VCC1 port isolated from the VCC2 port can provide logic inputs to reduce power consumption. L293D can work in the range of 0℃～70℃.IV. Circuit Design4.1 Introduction to Mobile Nurse RobotThe main purpose of the mobile nurse robot is to treat patients with medical staff, try to avoid contact with germs, reduce germ infection, reduce medical staff's concerns, and replace medical staff to do some simple tasks. In other industries, the robot can also do simple tasks for people, save labor, and improve social work efficiency.The mobile nurse robot is voice-controlled, and can automatically navigate according to the virtual track, and automatically detect metal during the navigation process, so that the robot can stop at a predetermined position and prompt the patient that the items needed have been delivered. Therefore, the mobile nurse robot has the following characteristics:Voice control function. The main control device of the robot is integrated with a voice recognition module, which receives voice control from a specific person, and the robot performs different operations according to different commands; Virtual track navigation function. The robot reads the data according to the infrared sensor installed on the main body, judges whether it deviates from the predetermined track, and corrects it to realize the function of virtual track navigation; Fixed-point positioning function. The tail of the robot detects metal according to the metal sensor, and performs corresponding stop and forward operations, so as to achieve the function of positioning the robot at a predetermined point; Voice playback function. The pre-input voice is played out at the fixed point to play the voice prompt function. 4.2 Peripheral Circuit Design of Motor Drive DeviceThe external circuit must be connected to a high-speed output clamp diode for transient suppression, as shown in Figure 2, just use the ordinary IN4001. When the input enable is low, the motor control output of the device is shielded. At this time, the motor control output of the device is closed and in a high impedance state. When the control signal is input to the input terminal of the device, all H reversible drive control solenoid or motor application circuit.Figure 2 LED external circuit diagram 4.3 Nurse Robot Circuit DesignThe main control circuit board of the nurse mobile robot performs the following functions: It can directly drive the DC motor of the mobile nurse  robot to control its actions; It can provide corresponding power to the DC motor, sensor, single-chip and switch on the robot; It can receive remote control signals. 4.4 Microcontroller and Its Peripheral Circuit DesignWhen selecting the single-chip microcomputer, the relevant materials of the obstacle avoidance mobile robot were consulted. Taking into account the design requirements of the nurse mobile robot, the cost-effective and powerful Sunplus Microcontroller SPCE061A was adopted. The peripheral circuit of the single-chip microcomputer in this design mainly refers to the SPCE061A simplified board circuit.  4.5 The Design of Power Supply and Its Device SelectionThe integration of the power supply part mainly uses the three-terminal integrated voltage stabilizer 7805. The output of the 78×× series is positive voltage, and the output power is different according to the different models. The output current of 78L×× series can reach 0.1A; the output current of 78M×× series can reach 0.5A. Taking into account the actual power consumption of the microcontroller, a 78M05 is selected to convert the 12V DC voltage into a 5V DC voltage.Sunplus’s SPY0029 can efficiently convert DC 5V to DC 3.3V. After testing, it is found that the output DC ripple is small, which can reliably ensure the CPU's 3.3V power supply. When the input voltage fluctuates to 7 V, the high-quality 3.3V DC output can still be guaranteed.The integrated power supply can provide the main control circuit board with DC 12V, DC 5V and DC 3.3V three power sources, respectively, to supply power to the DC motor, sensor, and CPU of the main control board to meet the design requirements. 4.6 Hardware Connection Diagram and Software DesignUse SPCE061A to control the robot, use IOB3~IOB6 and IOA0~IOA11 ports, as well as speaker infrared sensor, metal sensor, trigger switch, remote control module, etc. Figure 3 shows the circuit connection of the main control board of the nurse mobile robot. Figure 4 shows the design flow chart of the main control software of the nurse mobile robot. The main control board is mainly used to receive control signals (the nurse mobile robot sensitively receives the control signals sent by the part) and perform corresponding operations. The actions of forward, turn left, and turn right are relatively simple and will not be described in detail here.Figure 3 Block diagram of main control board circuit connectionFigure 4 Flow chart of the software design of the main control board of the robotThe virtual track navigation part involves the reading and judgment of sensor signals and the completion of the navigation process, which are the core of this design. The following is the interface program code of the MCU to control the motor through the L293D: V. ConclusionThe mobile nurse robot combines mechanical technology, electronic circuit design and software design, and expands part of the drive circuit of the DC motor on the basis of the single-chip SPCE061A. In practical applications, the combination of L293D and single-chip microcomputer has good control effect and high sensitivity on DC motors, and can complete virtual track navigation。FAQWhat is l293d?L293D IC is a dual H-bridge motor driver IC. One H-bridge is capable to drive a dc motor in bidirectional.

The drivers can be paralleled for even higher current output. Even further, stacking one chip on top of another, both electrically and physically, has been done. Generally it can also be used for interfacing with a stepper motor, where the motor requires high ratings which cannot be provided by other interfacing devices.ULN2003 Main specifications:500 mA rated collector current (single output)50 V output (there is a version that supports 100 V output)Includes output flyback diodesInputs compatible with TTL and 5-V CMOS logicULN2003A AdvantagesThe ULN2003A is an array of seven NPN Darlington transistors capable of 500 mA, 50 V output. It features common-cathode flyback diodes for switching inductive loads. It can come in PDIP, SOIC, SOP or TSSOP packaging. In the same family are ULN2002A, ULN2004A, as well as ULQ2003A and ULQ2004A, designed for different logic input levels.The ULN2003A is also similar to the ULN2001A (4 inputs) and the ULN2801A, ULN2802A, ULN2803A, ULN2804A and ULN2805A, only differing in logic input levels (TTL, CMOS, PMOS) and number of in/outputs (4/7/8).Where to use ULN2003ULN2003 IC is one of the most commonly used Motor driver IC. This IC comes in handy when we need to drive high current loads using digital logic circuits like Op-maps, Timers, Gates, Arduino, PIC, ARM etc. For example a motor that requires 9V and 300mA to run cannot be powered by an Arduino I/O hence we use this IC to source enough current and voltage for the load. This IC is commonly used to drive Relay modules, Motors, high current LEDs and even Stepper Motors. So if you have anything that anything more than 5V 80mA to work, then this IC would be the right choice for you.How to use ULN2003The ULN2003 is a 16-pin IC. It has seven Darlington Pairs inside, where each can drive loads up to 50V and 500mA. For these seven Darlington Pairs we have seven Input and Output Pins. Adding to that we can a ground and Common pin. The ground pin, as usual is grounded and the usage of Common pin is optional. It might be surprising to note that this IC does not have any Vcc (power) pin; this is because the power required for the transistors to work will be drawn from the input pin itself. The below circuit is a simple circuit that can be used to test the working of ULN2003 IC. In the circuit consider the LED to be the loads and the logic pins (blue color) as the pins connected to the Digital circuit or Microcontroller like Arduino. Notice that the Positive pin of the LED is connected to the positive load voltage and the negative pin is connected to the output pin of the IC. This is because when the input pin of the IC gets high the respective output pin will get connected to ground. So when the negative terminal of the LED is grounded it completes the circuit and thus glows. The loads connected to the output pin can be maximum of 50C and 500mA each. However you can run higher current loads buy combining two or more output pins to gather. For example if you combine three pins you can drive up to (3*500mA) ~1.5A.The COM pin is connected to ground through a switch, this connection is optional. It can be used a test switch, meaning when this pin is grounded all the output pins will be grounded.ULN2003A ApplicationTypical usage of the ULN2003A is in driver circuits for relays, lamp and LED displays, stepper motors, logic buffers and line drivers.A ULN2003 installed in a breakout board to be used as a unipolar stepper motor driver with a 28BYJ stepper motor on the left.ULN2003A Package InformationULN2003A Representative Schematic DiagramProduct ManufacturerON Semiconductor (Nasdaq: ON) is driving energy efficient innovations, empowering customers to reduce global energy use.

This op amp has outstanding PSR and takes wide voltage supply range from ±2 V to ±20 V. The OP97 comes in either an 8-PDIP or an 8-SOIC package and has an operational range of -40°C to +85°C. The OP97 is ideal for high precision low-power applications. Product Pinout OP97 AmplifierOP97 CAD Model OP97 CAD ModelOP97 Pin ConfigurationPin NoPin NameDescription1NULLNull Pin2INV-INPUTInverting Input Pin3NON-INV-INPUTNon Inverting Input Pin4V-Negative Power Supply5OVER COMPOver Compensation Pin6OUTOutput Pin7V+Positive Power Supply Pin8NULLNull Pin OP97 AttributesSpecifications Supply Voltage±20 VInput Voltage2 ±20 VDifferential Input Voltage3±1 VDifferential Input Current3±10 mAOutput Short-Circuit DurationIndefiniteOperating Temperature Range OP97A (Z)55 to +125OP97E, F (P, Z, S)40 to +85Storage Temperature Range65 to +150Junction Temperature Range65 to +150Lead Temperature (Soldering, 60 sec)300-3dB Bandwidth900kHzSlew Rate200mV/sVos30VIb30pAInput Noise (nV/rtHz)14nV/rtHzVcc-Vee Supply (V)4 to 40Iq per Amplifier600A# OpAmps per Pkg1Operating Temp Range-55 to +125PackagesDIP,SOICOP97 FeaturesLow supply current: 600 μA maximumOP07 type performanceOffset voltage: 20 μV maximumOffset voltage drift: 0.6 μV/°C maximumVery low bias current25°C: 100 pA maximum−55°C to +125°C: 250 pA maximumHigh common-mode rejection: 114 dB minimumExtended industrial temperature range: −40°C to +85°COP97ApplicationsThe OP97 is a low-power alternative to the industry-standard precision op-amp, the OP07. The OP97 can be substituted directly into OP07, OP77, AD725, and PM1012 sockets with improved performance and/or less power dissipation and can be inserted into sockets conforming to the 741 pinout if nulling circuitry is not used. Generally, nulling circuitry used with earlier generation amplifiers is rendered superfluous by the extremely low offset voltage of the OP97 and can be removed without compromising circuit performance. Extremely low bias current over the full military temperature range makes the OP97 attractive for use in sample-and-hold amplifiers, peak detectors, and log amplifiers that must operate over a wide temperature range. Balancing input resistances is not necessary with the OP97. Offset voltage and TCVOS are degraded only minimally by high source resistance, even when unbalanced. OP97 Applications Circuit OP97 Circuit Component DatasheetOP97 DatasheetUsing WarningsNote: Please check their parameters and pin configuration before replacing them in your circuit. FAQWhat kind of amplifiers are used in op97?The OP-97 will upgrade circuit designs using 725, OP05, OP07, OP12, and 1012 type amplifiers. It may replace 741-type amplifiers in circuits without nullling or where the nulling circuitry has been removed. At least one model within this product family is in production and available for purchase.What is the offset voltage of an op97?Offset voltage is an ultra-low 25µV, and drift over temperature is below 0.6µV/°C. External offset trimming is not required in the majority of circuits. Improvements have been made over OP-07 specifications in several areas. Notable is bias current, which remains below 250pA over the full military temperature range.  What is the PSR of the op-97?Outstanding PSR, a supply range specified from ±2.25V to ±20V and the OP-97's minimal power requirements combine to make the OP-97 a preferred device for portable and battery-powered instruments. The OP-97 conforms to the OP-07 pinout, with the null potentimeter connected between pins 1 and 8 with the wiper to V+.
