This is a simple clap switch circuit with high sensitivity. The only unusual component is the single coil latching relay. While there are numerous means of generating the latching function, the ...

and Clap Off! [Rutuvij] and [Ayush] bought a clap switch kit ... connecting a relay is a piece of cake. That’s the complete circuit of a clapper using five transistors, something that just ...

The circuits are about what you’d expect. The transistor version uses one to amplify the microphone and another to switch on the LED. You’d need a bit more to trigger a relay. The 555 uses an ...
