Project
Detecting Vibration with SW-420 on Raspberry Pi Pico
Overview
Learn how to use the SW-420 vibration sensor with a Raspberry Pi Pico to detect shaking or movement. This project is useful for tamper alarms, vibration alerts, and simple security systems.
Instructions
Step by step
1. Connect the SW-420 VCC pin to 3.3V.
2. Connect the SW-420 GND pin to GND.
3. Connect the SW-420 DO pin to GP17.
4. Run the code and open the Serial/console output.
5. Click or toggle the SW-420 sensor in the simulator.
6. When vibration is detected, the output should print "Vibration detected!".
7. When stable, the output should print "No vibration".
