| Abstract: | tin this paper, the circuit uses AT89C2051 as the central control unit, it can identify the pin and the type of BJT automatically. The circuit can automatically and rapidly identify the tube type and pins of low-power transistor, the judgment result will be shown in display circuit. This design has some advantage such as the circuit is relatively simple, testing is quickly and accurate, the instrument is has a low price and easy to expand and upgrade. |
