Back in 2009 I wrote an Arduino library ( IRRemote ) to encode and decode infrared signals for remote controls. I got an email recently fr...

A Rigol oscilloscope has a USB output, allowing you to control it with a computer and and perform additional processing externally. I was i...

I've extended my Arduino IRremote library to support RC6 codes up to 64 bits long. Now your Arduino can control your Xbox by acting a...

You can use an IR remote to control your computer's keyboard and mouse by using my Arduino IR remote library and a small microcontroll...

Thanks to Paul Stoffregen of PJRC , my Arduino IR remote library now runs on a bunch of different platforms, including the Teensy , Arduin...

I wrote an IR remote library for the Arduino ( details ) that has turned out to be popular. I want to make sure I don't break things a...

Oct 2016: An updated version of the code is on github , thanks to Gabriel Staples . The TV-B-Gone is a tiny infrared remote that can tu...

This article describes how to understand Sony IR codes and how to get them from the LIRC files. The article is intended to describe codes f...

One reader asked how to use my Arduino Infrared Library to detect breakage of an IR beam. The answer was too long for the comments section...

My latest project is controlling a pedestrian sign with an Arduino, so it will automatically step through the states of walk, flashing don&#...

My IRremote library decodes output from many infrared remotes: Sony, NEC, RC5, and RC6. However, many remotes use other protocols. While ...

I recently set up a web interface to my stereo, implementing it in both Python and Arc. I found that, much to my surprise, writing the Arc ...

I've ported the TV-B-Gone code to run on the Arduino board. If you haven't seen a TV-B-Gone, it's a cute gadget that you point...

Here's how you can control your stereo over the web. Not only that, but any other electronics with a IR remote control can now be contr...
