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 ...

Build a Speed Sensor using Arduino with IR speed sensors to accurately measure the speed of moving objects. This tutorial covers circuit design, sensor calibration, speed calculations, and optimized ...

This Arduino based IR reflectance sensor can be easily modified and adapted for various practical applications, including line-following robots and proximity or edge detection.

We’ve featured loads of IR Arduino projects and they are all exciting and unique. The projects spring from a specific need or problem where a custom infrared remote control is the solution. [… ...

Bidirectional Visitor Counter using Arduino UNO and IR Sensor Introduction The aim of this project is to develop a circuit that can count the number of people entering and exiting a room using two ...

This Arduino-based project simulates a two-floor elevator control system. The elevator uses IR sensors to detect the current floor and a single button to switch between floors. A seven-segment display ...
