A diode is a passive device that allows the flow of current in one direction only. But since there are so many types of a diode, it’s important to differentiate between them. And to know which one to use according to its requirement in our circuit. Given below is a detailed difference between diode, Zener diode, and Schottky Diode.
HOW TO MAKE A CONTINUITY TESTER CIRCUIT USING 555 TIMER
Continuity Tester is a simple electronics tool that indicates continuity of a circuit when that circuit is connected between the connecting probes of Continuity Tester Circuit. This Continuity Tester circuit can be easily made by using a simple 555 timer.
