If you’ve ever dealt with a brightly lit Christmas tree, you might understand the frustration of having to crawl underneath the tree to turn the lights on and off. [brmarcum] feel’s your pain. He’s ...

Gesture-controlled gadgets were all the rage at CES back in January. I’m still not convinced it’s a good way to change TV channels, but it can’t hurt to learn how to program for a motion sensor.

Last year, I took a look at some mostly low-cost passive infrared (PIR) motion sensor modules. Then recently, I became more aware of cheap microwave radar motion sensor modules. The popular version of ...
