Arduino clap switch – SOUND CONTROL SWITCH

Hello world! Today i made a Arduino clap switch with a DIY sound control module. I soldered the Sound control Module a few months ago, and today i decided to check out if it works, and it does. I had a hard time getting another value then 0 and then found a way to get 2 values. You can clap, knock, or say any word + you can blow into it.. for the last 2 you need to be close to the device. You can also use it as a shock/knock sensor. Check the next step for the schematic Code & Parts list.

For the Sound Switch Module:
Attach the Blue wire to SCL on arduino.
Attach the Yellow wire to RXD.
Attach the + to VIN.
– to ground.
