Sound Sensor (LM324)

Hi guys I haven't been here a while. :( Long story short, I got a new circuit for you :)

Arduino Ultrasonic Sensor HC-SR04

Hi guys!! Today I am going to show you how to use HC-SR04 ultrasonic sensor. First check out my video!

Arduino Traffic Lights

Hi guys!Today what we are going to do is traffic lights!I thinks its a good example to understant delay command.Of course we will use an arduino board and here is a video of mine.

Arduino Controlled Electronic Dice

Hi guys! Today I would like to share another fun project with you.An electronic dice.With this you don't need any real boring dice anymore.Unfortunately I don't have pictures of my circuit because I did it a time ago.But I have a video :) First here is a video of my dice.

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.
