Common Connections:

Vibration Module

  • D0: Connect to 7 on the Arduino.

  • GND: Connect to breadboard’s negative power bus.

  • VCC: Connect to breadboard’s passive power bus.

Writing the Code

Note

  • You can copy this code into Arduino IDE.

  • Don’t forget to select the board(Arduino UNO R4) and the correct port before clicking the Upload button.

/*
  Read the digital output value of the vibration sensor.
  When a vibration is detected, the program will display the message
  "Detected vibration..." on the serial monitor. Conversely,
  if there is no vibration, the program will output "..." instead.

  Board: Arduino Uno R3 (or R4)
  Component: Vibration Sensor(SW-420)
*/

// Digital pin connected to the vibration sensor
const int sensorPin = 7;

void setup() {
  Serial.begin(9600);          // Start serial communication
  pinMode(sensorPin, INPUT);  // Set sensor pin as input
}

void loop() {
  // Check if vibration is detected
  if (digitalRead(sensorPin)) {
    Serial.println("Detected vibration...");  // Output detection message
  }
  else {
    Serial.println("...");                    // No vibration detected
  }
  delay(100);  // Update interval
}
