After uploading the code the Piezo will start making short beeps. On bright light the Piezo will only beep and on dark light it will be short. Some ideas for this experiment: Alarm for Lights in the ...

The piezo disc sensor head (see above circuit) will keep A0 of Arduino at 0 V until it’s disturbed. Once the hardware setup is completed, upload the code, and hit the sensor head with your finger. In ...

The mouth sensors are just two piezo elements. Each sensor is hooked up to the Arduino through a small trim pot. This allows you to dial in the sensitivity of each sensor.
