Using a Piezo sensor to detect vibration. When detected have an alarm sound and a RGB led go off.

Changing an RGB led with 4 Pots. One of them controlling White, another Red, another Green, then Blue respectively.

The Code:

  Reads an analog input on pin 0, prints the result to the serial monitor.

  Attach the center pin of a potentiometer to pin A0, and the outside pins to +5V and ground.

   This example code is in the public domain.
