Old infrared remote controls can be a great way to interface with your projects. One of [AnalysIR’s] latest blog posts goes over the simplest way to create an Arduino based IR receiver, making it ...

Just because you missed out on National Arduino day doesn’t mean you can’t make every day an Arduino day—all you need is a hot, new exciting project to light a fire under that maker spirit of ...

This project demonstrates an Arduino-based Human Following Robot using IR sensors and an ultrasonic sensor. The robot detects a human presence in front of it and follows smoothly while correcting its ...

Arduino sensor projects blend coding with tangible results, making learning interactive, practical, and fun. From simple LED triggers to multi-sensor systems, these builds teach real-world electronics ...

I made this Arduino project that allows to turn ON and OFF LEDs using a cheap IR remote control as a preparation for the next big step: disassemble my girlfriend’s chinese LED lamp and replace its ...

Sensor‑based currency counter using an IR sensor and a colour sensor with an Arduino and 16x2 LCD. Notes are detected as they pass, their denomination is identified from colour patterns, and the ...

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 ...
