Sometimes, projects start in somewhat unlikely places. This one began when [Istvan Raduly] scored a fake raven at a neighbor’s garage sale and decided to turn it into a thunder-and-lightning ...

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 ...

The Arduino Plug and Make Kit provides a 10-minute, cloud-based IoT solution that includes QWIIC and smartphone-based sensors, transducers, and actuators. Arduino’s new QWIIC-based UNO Plug and Make ...

There are plenty of toys and board games that can teach kids about electronics, science and how things work, but few are as effective as an Arduino kit. These bundles include everything you need to ...

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 ...
