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 ...

Arduino is able to interpret signals from a variety of sensors. By placing a unit equipped with an ADXL345, an accelerometer ...

Piezo Trigger Switch circuit described here is a microcontroller-compatible shock/impact sensor switch module works on 5VDC supply. The whole circuit can be assembled on a 5×7 cm common circuit board.

For this project, you’ll need to write a program that tells the Arduino to trigger the camera and flash when it detects a sound. 2. Piezoelectric Sensor: This sensor will act as your sound detector.

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 ...

German developer and musician Alice Zeppa has created an umbrella that detects rainfall and turns it into 8-bit music. The prototype uses “one umbrella, 12 piezo sensors, two speakers, one ...
