Summary of Representing audio through vibration with Arduino
This project converts audio into tactile vibration so users (including deaf people) can feel sound loudness by connecting an audio source (iPod, computer, TV) to an Arduino-driven array of pager motors. It uses simple electronics on a breadboard with resistors, capacitors, LEDs, and a 3.5mm stereo jack; wires are soldered to the jack and components are arranged per the provided circuit diagram and Arduino code.
Parts used in the Representing audio through vibration with Arduino:
- Arduino
- USB Cable
- Computer running Arduino software
- Breadboard
- LEDs
- Pager Motors
- Three 100K resistors
- Six 220uF capacitors
- 1K potentiometer
- 3-Conductor Stereo 1/8 inch (3.5mm) Phone Jack
- Wires
- Solder
- Circuit diagram
- Arduino code
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.

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.
