Arduino based lie detector ?
Hey guys is there anyone who have any idea of making an Arduino based lie detector ?
Actually I saw in many movies that how chemical science is used to force someone to speak true and to detect whether he is saying true or lieing. Once I heard that our body creates vibrations and it is different when we lie and say truly. So I think this is possible to make such a device to detect whether someone is lieing or not. Did anyone have done it. ?
Kindly share your experience and guide me what type of sensors and what are the requirements needed to make such a device.
