Project 15: Hacking Buttons

Get control of other devices around you by pressing their buttons with Arduino! This project takes advantage of a special switch called an optocoupler which lets you operate one circuit with another. This can be used for hacking an existing device, and it's good to start with something simple, like a flashlight.
