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…
