During the night, no one wants to get up and walk all the way to your light switch just to be hit with a sudden extreme amount of light. Solution! A lighting system controlled by two claps. Just clap from wherever you are to turn on LEDs bright enough to light an entire room just the right amount. It looks for a clap and repeats the program in
loop(). I used four super bright LEDs, an Arduino Micro (any will work), and a sound sensor. Just clap twice to turn on and off.
