Environmental sensing technology has become increasingly vital in today’s world, where understanding and monitoring air quality and environmental conditions are crucial for sustainability and safety.

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

Creating capacitive touch-sensitive buttons is easy these days; many microcontrollers have cap-sense hardware built-in. This will work for simple on/off control, but what if you want a linear, ...
