![]() There are lots of transistor tester circuits on the web and they all do the one thing - identify a PNP or NPN transistor. Transistor Tester Transistor Tester To buy a kit: There is a certain amount of skill required to design a circuit but a lot of skill to simplify it. If the transistor is open, both LEDs will flash and if the transistor is shorted, neither LED will flash. ![]() If a good transistor is connected, it will produce a short across the LED pair when the voltage is in one direction and only one LED will flash. This allows the red and green LEDs to alternately flash when no transistor is connected to the tester. The other end of the circuit is connected to a voltage divider with the mid-point at approx 4.5v. Output pin 3 drives the circuit with a positive then zero voltage. ![]() ![]() Wirkam blogthis is a running message display circuit wherein the letters formed by the led arrangement light up.
