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 ...

Project Description This project simulates a piezoelectric energy harvesting system using Arduino. It monitors voltage generated by a piezo sensor, ambient light levels, and a manual override button ...

2. Piezoelectric Sensor: This sensor will act as your sound detector. When it picks up a sound, it sends a signal to the Arduino, which then triggers the camera and flash. 3.
