We have a collection of almost 500+ Arduino projects with Code, Circuit Diagram, and detailed explanations completely free for everyone to build and learn on their own. The IR sensor has a 3-pin ...

This repository contains documentation and code for a simulated Arduino lock system on Tinkercad. The system employs a servo motor controlled by an IR remote, with status indicators provided by LEDs ...

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 ...

In this structure, a colour sensor and an IR sensor are fixed with ... of the Note and send the color value to Arduino. And Arduino further calculates the currency value based on the color of the note ...
