Clap Switch Circuit Diagram. When you clap for the second time the relay is deactivated and the light is turned off. 1 x 3mm diffused red.
1 x 9014 transistor. 1 x pcb board color will be shipped out by randomly 4 x in4007. The circuit can sense the sound of claps from a distance of 1 2 meters.
The ic is working in monostable mode here.
This is another clap on off circuit diagram using 555 timer and 7474 ic. 1 x pcb board color will be shipped out by randomly 4 x in4007. Clap sound operated switch circuit. The ic is working in monostable mode here.
