Have you ever wondered how speed guns measure the speed of moving vehicles or how an athlete's sprint speed is recorded? Normally these speed sensors work with radar or laser technology to bounce back ...

The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...

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 ...

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 ...

A robust Arduino-powered robot engineered to autonomously follow a defined path using a five-sensor IR array and advanced feedback logic. This project demonstrates practical embedded systems design, ...
