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...

An Arduino can be used to turn devices on and off via an infrared remote. As an entirely impractical example of how to use my Arduino infrar...

I've implemented a simple IR universal remote that will record an IR code and retransmit it on demand as an example for my IR library . ...

Update The easiest way to use the library is through the Arduino IDE's library manager; the library is "IRremote". The code i...

I'm using my Arc web server running on an ARM-based SheevaPlug to get analog data from my Arduino. The frame below and the graph of tem...

Pulse-width modulation (PWM) can be implemented on the Arduino in several ways. This article explains simple PWM techniques, as well as how...
