Controlling an LED with Arduino Using an IR Sensor An Infrared (IR) sensor is a commonly used device for proximity detection and object sensing. When combined with an Arduino and an LED, it can create ...

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 ...

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 ...

This project is an Arduino-based obstacle-avoiding robot that uses both ultrasonic and infrared (IR) sensors for navigation. The robot moves forward while continuously scanning for obstacles. If an ...

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 ...

Imec, the nanoelectronics and digital technologies research hub, has announced the successful integration of a pinned photodiode structure into thin-film image sensors. With the addition of a ...
