This project is inspired by ArduTester V1.13: The Arduino UNO Transistor Tester, in fact, hardware is the same and schematic is almost identical. I assembled tester using instruction from original ...

Проверка на исправность. Определение типа (npn / pnp). Определение пинов (база, эмиттер, коллектор). Точность определения типа 100%. Точность ...

The two types of standard transistors are PNP and NPN which differs in circuit symbols. The layers of semiconductor material used to make the transistor are denoted by the letters. To keep a straight ...

From a simple electronic toothbrush to complicated robotics systems, DC motors are present everywhere. In most of our previous Arduino projects, we have used these DC motors as actuators and ...

In the early days, PNP bipolar transistors were common, but the bulk of circuits you see today use NPN transistors. As [Aaron Danner] points out, many people think PNP transistors are “backward” but ...

A previous Design Idea describes a circuit that uses an astable multivibrator to drive an LED (Reference 1). The circuit in Figure 1 uses a simpler alternative approach. The circuit uses a 2N3904 NPN ...
