It is likely that many of us will at some time have experimented with motion detectors. Our Arduinos, Raspberry Pis, Beaglebones or whatever will have been hooked up to ultrasonic or PIR boards which ...

Let me introduce another simple microcontroller-based do-it-yourself circuit that detects motion and excites a light source in a flash. The “snooper” here is an ordinary passive infrared (PIR) motion ...

If you’d like to monitor noises around your home or in your local facility you might be interested in an innovative project created by Christopher Cooper. Who noticed a substantial increase in the ...

Check out this Arduino-based electronic component tester. The device is intended to give a simple way to test transistors, resistors, capacitors, diodes and MOSFETs, and such like. The Arduino tester ...

We’re still not sure exactly how [connornishijima]’s motion detector works, though many readers offered plausible explanations in the comments the last time we covered it. It works well enough, though ...

This project is a simple modification of the LightGauge project. Instead of measuring light, we measure the ambient voltage field on pin A5 and use it to detect if someone is too close to our Arduino.

A new Instructables page has been created to make an eco-friendly DIY metal detector using an Arduino Mega just been combined with a 3.2 inch TFT LCD touchscreen to provide a fantastic readout, making ...

If you were wondering what happened to the Arduino Yun after it missed its original June release target, you can relax: it's now on sale worldwide. As promised, the $69 (€52) design combines a garden ...
