Blink a LED using your mind!

By stiumlating or relaxing your thought, you can turn an LED on or off. This project was done by reverse engineering a MindFlex Duel game and combining an Arduino to it. The Mindflex game comes with two single electrode EEG headsets that pick up the electric field change caused when you are critically thinking. By creating a series of high pass and low pass filters and adding an Arduino, I was able to blink an LED whenever a certain threshold was reached.
