sound sensor to act as button


Before i attempt to build the ciruitry, i was wondering if anyone knows if it's possible for the sound sensor to act as a button.

I want the sound sensor to detect a sound, and then allow for a separate circuit to be completed in the same fashion that pressing a button could complete a circuit. Hence, the sound sensor is acting as a button. I think i can make a clap light with no relay board but not sure if logic will allow this.

Thanks guys :slight_smile:

Yes it is possible.

The sound sensor, on detecting a sound, will send a signal to the Arduino or other Microcontroller. The Arduino can then do the required switching. If its a small low current load, a transistor or mosfet can do it. But for turning on/off home lights use a relay.
