Example Code for Arduino-Vibration Detection

Hardware Preparation

• DFRduino UNO x1
• Flexible Piezo Film Vibration Sensor x1
• M-M/F-M/F-F Jumper wires

Software Preparation

• Arduino IDE, Click to Download Arduino IDE from Arduino®

Wiring Diagram

Note: Turn the switch to "D" side

Other Preparation Work

Note: The sensitivity potentiometer control the output threshold. When it rotates towards "MAX" direction, it need more swing to trigger sensor.
