Story

Our skin is amazing! It provides a medium for us to experience the sense of touch. It keeps infections out and keeps innards in but I bet you didn’t know that our skin changes conductivity depending on many different things one being our mood! It is called Electrodermal activity (EDA) and there’s a really interesting Wikipedia page you can read here. The basics are that our skin changes its conductivity depending on how we feel. So tody we are going to make a Lie Detector using Arduino. This lie Detector will detect if the person on whom we are testing this is telling a lie or not.

We start by connect our Arduino to the subject. Then connect the Arduino to a computer with the graphing software (I’ll go over this in detail later).

Lets start by asking the subject some easy questions. We know they will answer truthfully like “What is your name?” and “Where do you live?” to get a baseline and from there we can start asking questions that they may lie about. If they do they would probably feel nervous and then we can read the change in the base line that be established earlier if they lie :D.
