Spy Kit: Lie Detector

This project simulates the Galvanic Skin Response to determine whether an individual is being truthful, using an Arduino to detect the change in skin resistance.

In the first lesson, you will create a prototype circuit for the Lie Detector Project. In the second lesson, you will use common TinkerCAD tools and actions to create a 3D printed finger bed. The final lesson shows you how to create a real-life version of the Lie Detector circuit prototyped in 123D Circuits.
