Simple & easy DIY Continuity Tester using LED Tutorial

In this video, I made a continuity tester for the checking the connection continuation.

Things Required -

Flexible Wire



2 pens


I made this by using two pens as the tester terminals where for terminals, I used flexible wires for that. Further, it is just making a circuit. You can use a light, a buzzer or a vibrating motor as well which could just give a signal about the connection status.
