We have previously posted the the project lie detector, now here is is also a lie detector using arduino. Here is a simple tutorial to build a simple lie detector which will give visual indication through LED arrangement whether the person speaks lie or truth. The project uses a arduino duemilanove or uno. So the project is based on […]

I’ve built a number of projects that have interfaced the output of the Simple Bat Detector with a microprocessor. The most recent was the BatLogger II. But I hadn’t come up with an easy way for others to experiment with this idea … until now. My friend, Frank, in Germany, had wanted to make a

When your coin slot is exposed, this wearable hip-pack vibrates that area to make you aware of it. You decide to cover up, or let it all hang out. The coin slot detector is a simple way to tackle the complicated modern problem low-rise jeans can cause. with this hip pack, now your coin slot

his is a preliminary instructable that will take you through the steps I took to get the SR04 ULTRASONIC SENSOR connected and working to the Arduino. It will then be incorporated to my mini environment monitor. Eventually, if it all fits, it will end up in a Startrek toy tricorder casing I found in my

Abstract: A PIN photodiode, four low-noise op amps and a comparator are used to detect individual photons of gamma radiation. The schematic, design considerations and component selection are discussed. The circuit of Figure 1 includes a PIN photodiode that detects individual photons of gamma radiation. When a photon strikes a depletion region created by reverse bias

Here’s a small, quick project you can do with an arduino, the EMF Detector! Step 1: Circut All you need for this project is 10- 330 ohm resistors 10- LED’s 1-3.3m resistor 1-Solid core wire (this will serve as the probe) breadboard, wires, battery & connector for arduino to make it portable Step 2: Hooking
