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. Th ...
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.Capacitor, a electronic component to hold charges, represented by the letter C. It composes of two metal electrodes between a la ...
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 erro ...
IntroductionThe 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 resist ...
IntroductionHow to Read an Electrical Diagram LessonCircuit 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, and provide pl ...
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 ...
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, th ...
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  ...
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 resistan ...
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. ...
IntroductionWith the development of science and technology, electronic products are changing with each passing day. Also the electronic assembly technology is facing challenges. Following the development of electronic technology, people work harder to make innovation in electronic assembly technolog ...
IntroductionElectronic Basics #14: CapacitorsSolid-state capacitor is called solid-state aluminum electrolytic capacitor. The biggest difference between it and ordinary capacitors (i.e. liquid aluminum electrolytic capacitors) lies in the use of different dielectric materials. The dielectric materia ...
PrincipleWhen an operational amplifier is used, its output is connected to its inverTIng input node to form a negative feedback configuration—negaTIve. The reason is that the voltage gain of the operational amplifier is very large, ranging from hundreds to tens of thousands of times, the use of nega ...
