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 ...

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. [Rick’s] ...

If you’ve ever needed a short-range remote control for a project, [firestorm] is here to help you out. He put up a great tutorial on using an IR remote to do just about anything with everyone’s ...

Connect IR sensor on pin 9 and two push buttons on pin 10 and 11, respectively. Also keep an IR remote handy.

Requires the IRremote library, this is included in the lib directory of the project along with many examples. The remote sends a number of hexadecimal values representing functions on the remote. The ...

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 ...

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 ...

The board may be used as a platform for the rapid development of various new smart system and IoT applications. Potential use cases include: Presence detection and detection of abnormal behaviour to ...
