Adalight with FastLED

I’ve previously mentioned that I was initially using this code by James Bruce to drive the ambilight. While I was waiting for the circuit board components to arrive, I thought I would take some time to expand on his work, fix some bugs, and add a few features I thought were missing. After a few recent tweaks it’s now ready for distribution. Presenting: Adalight-FastLED! I’ve reworked the Adalight code to provide user-friendly options that allow you to easily customize it for your setup. I also added a brightness limiter and a calibration mode, which sets all LEDs to the same…

PC Software Options for Adalight – Processing vs Prismatik

Once the LED strip has been soldered together and attached behind the monitor, the next step is to configure the software on the PC. The communication protocol for Adalight is quite simple, which means there is a variety of PC software that can send color information to the Arduino. There are other options, but the two I’ll cover are Processing and Prismatik.

DIY Ambilight: Prepping the WS2812B Strip

The first step in taking the Arduino-based ‘ambilight’ from concept to completion is to modify the LED strip so it fits nicely around the monitor.  Like most addressable LEDs, the 5m roll I’m using has cut lines where you can trim it.  Because each pixel is its own self-contained circuit, you can arrange them in any shape or number you can think of so long as you connect the three wires: power, ground, and data.
