Simple Lie Detector Circuit

Build a simple lie detector circuit on PCB. Find here the details: https://circuitdigest.com/electronic-... In this video, we built a simple fun circuit. The concept behind this Lie Detector Circuit is that we assume when a person lies, he kind of pumps up his anxiety level which makes him sweat and develop moisture on his skin. We then use this circuit to detect if there is moisture on his skin and based on the result, we glow an LED, a green one for truth and a red for the lie. Of course yes, this cannot be claimed as a lie detector, but you can use this to play with your friends and have fun. More than that, you get to learn stuff. #Liedetector #DIYelectronics
