Arduino Water Boarding
A lie is the sin man tells in fear. To seek the truth, we must aide the sinner in crossing a threshold to find deliverance. Problem is, I am binge watching Ally McBeal Season 4, so allow us to automate the process. Attach sensors to said victim...er...suspect and allow our computer (Jacob) and an Arduino Uno to decipher if they are telling the truth or require some, inspiration.


A notation; the quality of this video is sub-par because I often shoot on poverty driven video equipment, namely an elderly Droid Razr. Forgive the potato.
