Detect Lies with Tin Foil, Wire, and Arduino

This is just for fun. You can’t really detect lies with this project. But you can learn about how what we think and feel affects what our body does. That’s pretty cool. This project detects electrodermal activity. You might know it as galvanic skin response (GSR), from TV cop shows.

Everything you need to build this is in the kit, except some tin foil and Velcro. There’s a good chance you have those in the house already. Basically, you connect a ground wire to the tinfoil, make an electrode wrap, hook that up to the Arduino properly and add the right program. An Arduino program is called a “sketch” Which Programming Languages Can You Use With Arduino? Which Programming Languages Can You Use With Arduino? Ready to try something different with your Arduino?

A Simple Arduino Battery Tester

Anybody can use a store-bought battery tester, but not just anyone can build one. Okay, maybe anyone can if they have an Arduino starter kit. Using your Arduino board, 3 LEDS, bread board, a Zener diode, and some of the jumper wires, you can make a unit to tell you roughly how much juice is left in your battery. Plus it gives you an excuse to say Zener diode. Throw that in your next conversation with your buddies for some instant electronics geek cred Level Up Your Geek Credentials With Any of These 5 Programming Projects Level Up Your Geek Credentials With Any of These 5 Programming Projects Read More .

If you enjoy making that one, consider adding a readout to your LCD module. Then you could get exact voltages. If your kit doesn’t come with a Zener diode, you can get 10 of them for about $7.00. Never hurts to have a few spares. Gives you more chances to say Zener diode later on.

Home Made Arduino RADAR

One of the great things about learning to build stuff with an Arduino, is how it can often help you learn about other technology. In this case, it’s radio detection and ranging 6 Effective Tools To Avoid Police Radar Speed Traps 6 Effective Tools To Avoid Police Radar Speed Traps Read More (RADAR).

Using the ultrasonic sensor, servo controller and motor, the Arduino board and some other bits, you can make a sweeping RADAR device. If you take the time to work out the math in the sketch, it can be surprisingly accurate about the distance of things it sees. This project uses another piece of software called Processing Learn to Program in Processing: A Language for Visual Designers Learn to Program in Processing: A Language for Visual Designers The 21st Century is open to creativity through digital means and programming. Would you be surprised to learn that there is a programming language out there designed for the artist in you? Read More , which looks a lot like the Arduino app, but is used to visualise the ultrasonic sensor output.

Sure, it’s a very short-range RADAR, but also very cool looking and will give you lots of other ideas about using ultrasonic sensors 8 Arduino Robots You Can Build for Less than $125 8 Arduino Robots You Can Build for Less than $125 Read More in other projects.

The first one in the video above gives its results via a single LED. But you could do so much more! You could try the LED bar also shown in the video, or have an EMF count show on a 7-segment display, or have it make a sound with a piezo buzzer, kind of like a Geiger counter. If you’re feeling adventurous, try building in LEDs, an analog gauge, and the piezo buzzer. Once you’ve built the basic one, you’ll probably be able to figure out a Sam and Dean Winchester approved version.
