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 ...

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.

This project involves creating a simple door status monitor using an Arduino Uno, an IR sensor, and an LED. The purpose of this project is to detect whether a door is open or closed and display the ...

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 ...
