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.

Representing audio
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

Representing audio Schematic

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.
