The Lie Detector

The Lie Detector is made with two recycled DC motors from old printers. The circuit is made up of a triple 5 timer and two transistors for the hand sensor. The buzzer goes off when it gets a strong enough signal coming from the sensor. The more your hand sweats, the stronger the pen moves and buzzer sounds. I love this project because I'm finally branching away from microcontrollers.
