Vibration Module with Raspberry PI: Wiring Diagram and Python Code


Last Updated on 22nd March 2024 by peppe8o

This tutorial shows how to connect and use a vibration module with Raspberry PI computer board using Python.

One of the most effective and immediate feedback to the user, the Vibration Module with Raspberry PI adds a prompt vibration notice to your projects

How Vibration Motors work

While the vibration module gives a device that makes your code independent from the used technology, it’s good to know that there are several kinds of vibration motors. the main ones are below described.

Eccentric Rotating Mass (ERM) motors have been the original way to generate vibration.

They are composed of a common DC motor that activates an eccentric mass. The mass rotation produces an unbalanced lateral movement that simulates a vibration.

Eccentric Rotating Mass (ERM), ref.

The Linear Resonant Actuators (LRA) work more like a loud speaker. It includes a mass which is moved back and forth by a voice coil and a spring.

The vibration switch module we’re going to use is an LRA type.


It has 3 PINs. The signal (IN) activates the vibration. The VCC and the GND bring the current to the module in order to make it work. Some models have a V+ label instead of Vcc.

What We Need

As usual, I suggest adding from now to your favourite e-commerce shopping cart all the needed hardware, so that at the end you will be able to evaluate overall costs and decide if to continue with the project or remove them from the shopping cart. So, hardware will be only:

Step-by-Step Procedure

Vibration Module and Raspberry PI Wiring Diagram

Prepare connections as shown in the following picture, according to Raspberry PI Pinout (that is the same as Raspberry PI Zero Pinout):

+3,3V (or 5V)Vcc (or V+)

Prepare The Operating System

Start with OS installation using install Raspberry PI OS Lite guide, to have a headless OS and work from a remote SSH shell. This procedure also works with Raspberry PI OS Desktop, using its internal terminal or Thonny IDE. Make your OS up-to-date. From the terminal, use the following commands:

sudo apt update -y && sudo apt upgrade -y

The Raspberry PI OS installation should already include the RPI.GPIO package (otherwise, you can install it with the command “sudo apt install python3-rpi.gpio”).

To use the vibration module with Raspberry PI we don’t need specific packages, so we can go on directly with the Python code.

Get my Python Script

You can get my test code directly into your Raspberry PI with the following command:


The following lines will explain how this code works.

In the beginning, required modules are imported:

import RPi.GPIO as GPIO
import time

As from best coding practices, we’ll use a variable to store the GPIO port number where the vibration module signal PIN is connected. We also set the naming convention to Broadcom (BCM) and the vibration pin to output:

vibration_pin = 27
GPIO.setup(vibration_pin, GPIO.OUT)

Instead of writing the lines to activate the vibration within the main code, I usually prefer to define a custom function that I can call from my code in order to execute the vibration feedback. The vibrate() function does just this: it activates the vibration module by putting to high the related PIN, then waits 0,5 seconds, and finally deactivates the vibration module. Running this function will result in getting a 0,5 second vibration:

def vibrate():
    GPIO.output(vibration_pin, GPIO.HIGH)
    GPIO.output(vibration_pin, GPIO.LOW)

At this point, the code hasn’t performed any physical activity, as we’ve just set all the necessary things to make the vibration perform in a very simple way. With the initial code so defined, we can perform a vibration by just running the following line:


A final cleanup will make our GPIO ports in a clean status before ending the Python code so that no warning will occur on the next code execution:


Run the Vibration Module with Raspberry PI

Please use the following terminal command in order to get the vibration running:


This will execute the vibration and exit from the script.
