Food Detector with Arduino

Hi guys!Today I am going to show you how to make your own food detector by measuring foods resistance.

Arduino Polygraph(Basic Lie Detector)

Hi.In my first tutorial I would like to show you "How to make a simple polygraph machine with arduino?".It's a really simple project and I will explain the operating logic.But you can't use this project to detect lies about important situations.This project is not equal to professional machines.So please use it just for fun.
