Adalight – DIY Ambient Monitor Lighting Project Pack

Build your own ambient-light addition for a monitor or media PC television with the Adalight project pack! This project pack is for our “Adalight” project tutorial. By running the Processing code on your computer, the halo of LEDs will follow the screen colors to provide an awesome ambient light display that adds pop to TV shows, movies or games! Works using open source Processing and Arduino – so it’ll run on Mac, Windows or Linux computers!

This pack contains:

• A strand of 25 x 12mm LED pixels
• 5V 2A power adapter – this is a 100V-250V adapter, so you can use it anywhere in the world. Outside the US/Canada/Japan you will need a simple plug adapter, available at any hardware/electronics store for about $1
• 2.1mm female power jack

You’ll also need an Arduino (or compatible) and a USB cable, those are not included! You will also need some basic soldering tools and some wire, see the tutorial page for instructions.
