This project was made for the Makey Makey. As a result, it seems kind of lame. However, it's real world counterpart is quite cool. My sister and I found the instructions for this project in the book "20 Makey Makey Projects for the Evil Genius", in case you want to go check that out. Anyway, press the space key to deactivate the alarm.
Makey Makey and my sister, for helping me build this.
