Representing Audio Through Vibration With Arduino




Introduction: Representing Audio Through Vibration With Arduino

This project functions to display sound using vibration. You plug your iPod, computer, or TV into it and get tactile feedback representing the loudness of the audio.It can help deaf people to experience sound.

Wire strippers
Needle nose pliers
Soldering Iron

Stuff you need:
USB Cable
Computer running Arduino software (
Pager Motors
Three 100K resistors
Six 220uF resistors
1K potentiometer
3-Conductor Stereo 1/8" (3.5mm) Phone Jack
Circuit diagram
Arduino code

Step 1: Cut Wires and Strip Those Entire Wires Ends 1/2 Cm

Use wire stripper to cut and strip.
Cut 8 1” pieces of wires for LEDs, Phone Jack and breadboard.
Cut 8 3" pieces of wires for connecting between Arduino pins and breadboard
Cut 6 5" pieces of wires for pager motors

Strip those entire wires’ ends ½ cm

Step 2: Solder the Wires to 3-conductor Stereo 1/8 Phone Jack

Warning: Soldering Iron is very hot  It's little hard to solder between wires and pager motors' wires because pager motors' wires are very tiny.

Use six 5" wires for this.  You can twist black and red wire together but make sure that both wire metals doesn't touch each other.  Otherwise it will be short circuit break and you may damage pager motors.

black wire to blue wire of pager motor for ground
red wire to red wire of pager motor for power

Step 3: Set Up the Breadboard and Follow Circuit Diagram

Follow a circuit diagram and set up the breadboard how circuit diagram tells you using small pieces of wires. Insert resistors, LEDs, pager motors, capacitor and phone jack.

Step 4: Connect the Arduino Board

Connect the breadboard to the Arduino board with stripped wires.

Step 5: Download and Open Arduino Code

Download and open Arduino code, and upload the code to the connected board with the Arduino software

Step 6: Test Your Circuit With Sound

Test your circuit with sound from your computer's headphone jack.  Turn your volume up if you don't see LEDs light up and pager motors vibrate.

Step 7: Modify Your Own Code to Work With Your Experience!

Modify your own code to work with your experience!

    This is really interesting but I wondered if there was a video of this actually working? I want to vibrate and reverb windchimes (analogue sound) physically using an audino as what I am making is open to the public. But I don't want to invest money into buying equipment through this guide if it isn't illustrating what I want. I'm worried it's ony showing digital sound?

    Anyone completed this? Some of the steps simply don't match the picture.. hahaha I'm lost. The 1K potentiometer shows in 1 picture only is it needed or not? ladailey I believe he meant to use the 6 resistors for the output and well... gone.. lol

    This project is very interesting. However when I try to find the 3-Conductor Stereo 1/8" (3.5mm) Phone Jack on amazon, it


    which does not look like what you have shown. Does it have any other name?

    I checked your link and it went to the main menu. Can you send me a link again?

    I would also like to ask what part is the phone jack connected to on the breadboard? What is the name of that component?

    I'd really like to make this project.

    By comparing the photos and the parts list, it seems to require three 100K resistors, ONE 220uF capacitor, six other resistors that, by the color in the photos, appear to be 260 ohm (red, blue, brown, gold). Is this correct?

    I, also, am having difficulties understanding the wiring. I do not see the six resistors or the six diodes in the schematic. Can someone help? Has someone built this?

    Sensory substitution! I did my honors thesis in college on perception using a device like this to translate visual stimuli into tactile vibrations. Just excited to see others using similar concepts :-D

    Can you add some details on:- -How to do the connection for phone Jack? - How to connect the potentiometer as I dont see it being used here in the shown circuit ?
