Furthermore, the vacant solder pads near the three-pin interface header is for mounting a light-dependent resistor (LDR/CdS cell). This, if added, causes the detector to be operational only when the ...

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 ...

Halloween is coming up faster than you think: time to dust off the gravestones and the zombie lawn decorations! This year you may want to add a little something extra to give the trick-or-treaters a ...

The Leap Motion controller is a rather impressive little sensor bar that is capable of generating a massive 3D point cloud and recognizing hands and fingers to allow for gesture control based ...

Arduino platform makers, hobbyists and developers may be interested in a new Arduino Serial Camera Module which has been created by GHI Electronics and provides the ability to capture time-lapse and ...
