Representing audio through vibration with Arduino

introRepresenting 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.

Tools :
Wire strippers
Needle nose pliers
Soldering Iron

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

step 1Cut 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 2Solder 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 3Set 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. i step 4Connect the Arduino board Connect the breadboard to the Arduino board with stripped wires. step 5Download and open Arduino Code Download and open Arduino code, and upload the code to the connected board with the Arduino software i Sound_Visualization_Pager_Motor_v3.pde2 KB step 6Test 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 7Modify your own code to work with your experience! Modify your own code to work with your experience!
