[Fjord Carver] brings together an RGB LED and CdS Photoresistor to make a color sensor. Those Cadmium Sulfide lights sensors usually have a very wide swing of resistance when exposed to varying lev… ...

He suspected EMF interference so as a quick first step he decided to throw together an EMF detector using an Arduino. It uses a bank of LEDs as an indicator bar to reflect the EMF picked up by the ...

The Pressure Sensor Module incorporates a material called Velostat with the Arduino. This material adds more resistance when more pressure is applied to the material. This module also uses the RGB LED ...

If you've always wanted to try to build an Arduino project, this may be a great way to start. Matt Williamson built a tiny, Arduino-based motion sensor that will SMS you when something moves by ...

Anyone can hang a poster from the wall, but if you're willing to put a little DIY into your home decorations, this Arduino-powered LED wall-art looks amazing, and reacts to music playing in the ...

Engineers at Columbia University have created a force-sensitive finger for robots that senses in all directions. “There has long been a gap between stand-alone tactile sensors and fully integrated ...
