Hello every one . here I show my project TV remote controllable computer MP3 player using processing software and arduino board. This project idea is based on controlling computer using TV remote control. In this project I created custom MP3 player using processing software and I programmed the arduino board to decode the IR remote control signal and communicate with processing custom mp3 player using serial communication. So by using this project I can play , pause the player song and also change the song forward and backward direction using my IR remote control. lets start building the project.
