KitsGuru Continuity Tester LGKT071 Educational Electronic Hobby Kit

The kit Continuity Tester circuit will detect continuity between two points. Basically this circuit used as any PCB testing, continuity testing, wire testing etc.The kit Continuity Tester based on 555 Timer IC which is using as monostble multivibrator mode. In this kit we can check the continuity between two points whether check the continuity between two points or not. This circuit will detect low resistances and high resistances to produce a tone from the speaker. It will detect up to 200k and the circuit automatically turns off when the probes are not used. There are two points in the PCB board which is connected to a two pin connector. The output an 8 ohm speaker connected for continuity check. Finally check the continuity between two points.
