You’ve heard a lot about ‘Internet of Things’ and probably bought yourself an Arduino kit along with a few more sensors but you can’t figure out how to exactly use them! If that sounds like you, then ...

Working with multiple sensors on an Arduino can unlock richer, more interactive projects. By integrating motion, light, distance, and environmental readings, you can create systems that respond ...

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 ...

Recent Arduino projects showcase increasingly sophisticated multi-sensor integration, from multiplexers solving I²C address conflicts to interactive hubs with multiple modes. Developers are pairing ...

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 ...
