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 ...

Recently, I exhausted my stock of common passive infrared (PIR) motion sensor modules and was looking for a new one to play with. I searched the web for a small type with self-contained electronics.

Wireless sensor networks are nothing new to Hackaday, but [Felix]’s wireless PIR sensor node is something else entirely. Rarely do we see something so well put together that’s also so well designed ...

The world of littleBits (the “not-a-toy” toy that I reaaaally wish existed when I was younger) just got a little bit bigger: it can now play friendly with Arduino. If you’re not familiar with ...

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 ...

Anyone searching for an Arduino project to keep them busy this weekend may be interested in a new motion activated wildlife camera constructed using the Adafruit Feather M0 development board. Created ...
