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 ...

Hardware Requirements Arduino Uno or similar microcontroller Breadboard for assembling the circuit Capacitive Touch Sensor (e.g., MPR121 or a DIY capacitive sensor circuit) Conductive Wire to connect ...

This project uses a piezoelectric transducer to generate electricity when subjected to mechanical stress (e.g., pressing or tapping). The generated energy is used to illuminate an LED and monitored ...

The piezo sensor detects your knocking as an input. It can even listen to and repeat back a series of your knocks. The Arduino actuates the solenoid, which strikes the wooden enclosure, producing ...
