What is an AVR microcontroller?AVR microcontroller is an enhanced 8-bit and built-in Flash RISC order set developed by ATMEL. Compared with CISC, RISC is not just to reduce the command simply, but make the structure of the computer more simple and reasonable to improve the speed of the operation. The design absorbs the advantages of 8051 and PIC microcontroller, and has the ability to execute one instruction in a single clock cycle. The speed can reach 1Mips/MHz. AVR microcontrollers are widely  ...
IntroductionA capacitor is a passive two-terminal electronic component that stores electrical energy in an electric field.The effect of a capacitor is known as capacitance.What is a capacitor?Capacitor, a electronic component to hold charges, represented by the letter C. It composes of two metal electrodes between a layer of insulating dielectric. When a voltage is applied between the two metal electrodes, the charge is stored on the electrode, so the capacitor is an energy storage electrical pa ...
IntroductionPrinted circuit board, also known as PCB, is the electrical connection provider of the electronic components. It has been developed for more than 100 years; its key point is  about layout design. The main advantage of using circuit board is to greatly reduce wiring and assembly errors, improve the level of automation and productivity.Since printed circuit boards are not general end products, there is a slight confusion in the definition of it. For example, the motherboard for pe ...
IntroductionWhat is a resistor?The resistor is a passive electrical component to create resistance when electric current flowing. We can find it in all electrical networks and electronic circuits. The resistance is measured in ohms. An ohm is the resistance that occurs when a current of current passes through a resistor with a one volt drop across its terminals. Commonly used color band resistor can be divided into four-band and five-band, in practice, usually four-band. The front two bands ...
IntroductionHow to Read an Electrical Diagram LessonWhat is a circuit Diagram?Circuit diagram is the basic of engineering research and planning. A schematic layout diagram, which is drawn with the standard symbol of physical electricity, can show the working principle of each component and device relationship, Each electronic component has a symbol. After seeing a few circuit diagrams, you’ll quickly learn how to distinguish the different symbols, and provide planning plan for installing electro ...
Schematic DiagramsCLC П-Filter1. Working Principlea. When the positive pulse is input, C1 is charged first, the charging current is ic1, and meanwhile, reaching the peak voltage of pulse. The inductor L also has a linearly increasing current, and the magnetic energy is stored in L. With the increase of the current, more and more magnetic energy is stored, and the capacitor C2 is charged with voltage through inductor L (the charge current is ic2), the voltage of C2 is basically equal to the volta ...
IntroductionThe heat sink has a thermal conductor that carries heat away from the device into fins that provide a large surface area for the heat to dissipate throughout the rest of the components, thus cooling both the heat sink and processor. Both a heat sink and a radiator require airflow and, therefore, both have fans built in.At present, the main failure form of electronic equipment is thermal failure. According to statistics, 55% failure of electronic equipment is caused by temperature exc ...
How much do you really know about memory, or RAM and ROM specifically? Here we will tell them in different aspects, this article will act as a guide to basic memories.RAM | ROMROM and RAM belong to the semiconductor memory. ROM is the abbreviation of read only memory, and RAM is the abbreviation of random access memory. ROM can keep data when the system powers off, and RAM is in the opposite, a typical RAM is the computer memory.RAM | Two Major CategoriesRAM Upgrade Guide - What You Need to Know ...
The larger the resistance of the drive, the longer the turn-on time of MOSFET, and the longer the voltage and current overlap time in the switching time, the greater the switching loss. Therefore, the smaller the resistance, the better the drive resistance should be, provided that the drive resistance can provide enough damping to prevent the drive-current oscillation.When designing switch power supply or motor drive circuit with MOSFET, the factors such as on resistance, maximum voltage and max ...
IntroductionMany engineers who have not used the switching power supply may have some worry about it, such as the PCB layout, the parameter and type selection of components and so on. In fact, as long as you understand the basic principle, the use of switching power supply design is very convenient.A switch mode power supply usually consists of a controller and an output part. Some controllers integrate MOSFET into the chip, which makes it easier to use and simplify the PCB design, but the flexi ...
