While PIR sensors can be used with Arduino and other microcontroller boards, those best-suited for hobby use are smart enough to perform simple tasks without any programming.

I run it on a Raspberry Pi 5 with a fast M.2 NVMe SSD, and it handles everything from basic light controls to more complex motion-based routines.

Though Apple's HomeKit home automation platform has supported cameras for over a year, manufacturers have been slow to bring compatible devices to market. Learn how you can create your own HomeKit ...

These engines exhibit near-chaotic behavior and are very challenging to model, so he developed a machine learning algorithm on a Raspberry Pi that adaptively learns how to control the engine.
