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 ...

This project involves the development of a speed detection system using Arduino and IR sensors to monitor and alert traffic authorities about speeding violations on highways. The system calculates ...

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 ...

Arduino is a very popular open-source platform and Arduino UNO is one of the most loved microcontrollers among electronics hobbyists worldwide. It consists of a physical programmable circuit board and ...

Sometimes you need a little utility device to do a very simple job, and do it well.This one-shot IR helper from [Gregory Sanders] is just that. [Gregory] had a TV that didn’t support automatically ...

Abstract: For patients to receive good care, doctors must be present. To administer medication or provide treatment, he can’t be everywhere at once. If we regularly examine our health, we may be able ...

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 ...
