Photoelectric sensors detect objects and surface changes using variations in optical properties. Each sensor includes a light emitter and a receiver, with most relying on infrared light. In optical ...

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 ...

In Arduino IDE menu, go to Sketch -> Include Libray -> Add .ZIP Library... and then select the zipped library. After including it, you can add the include headers to your current sketch with Sketch -> ...

Hey makers and tinkerers! This pack includes 5 IR speed sensor modules perfect for measuring motor speed, counting pulses, or any project that needs precise rotation detection. Each module uses an ...

An AI-based speed limit detection and automatic speed control system using computer vision and embedded electronics. A TFLite model detects road signs via camera, Python processes data, and Arduino ...

Some readers may recall building a line-following robot during their school days. Involving some IR LEDs, perhaps a bit of LEGO, and plenty of trial-and-error, it was fun on a tiny scale. Now imagine ...
