Vibration

Course Introduction

In this lesson, we will learn how to use the Vibration Module with Arduino.

Note

If this is your first time working with an Arduino project, we recommend downloading and reviewing the basic materials first.

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
}
