Arduino Based PC Ambient Lighting. I really like the concept of ambient lighting systems which synchronize with entertainment to create a great immersive experience. And since I had a RGB led strip lying around I decided to use my Arduino and a Processing sketch to create such a system for computers which really turned out great! Here is a video of my setup and a nice demo of it working with a Star Wars video clip: Materials:If you would like to setup this system, it is quite simple and does not require any Arduino shields. The materials you will need other than an Arduino are:+RGB LED Strip (<=$15.95): You can get really cheap ones but I went with this Sparkfun LED strip due to ease of shipping ( +ULN2003A (~$00.63): This chip is a transistor array for driving the LED strip which requires 12V signals with the 5V digital signals from the Arduino (order from DigiKey: A closeup of my setup: Code: //Developed by Rajarshi Roy import java.awt.AWTException; void setup()
Home made Ambilight clone. Hydra (Dominic Clifton) Re: RaspiLight (ambient light) Sure. Hook up the raspberry pi as per this diagram: ... i/hardware Ensure you use a common ground when wiring up. I found the LEDs did not work if i powered the RPI and LEDs seperately. I found an old 5V 2A PSU I had lying around and that is fine for my WS2801 104 LEDs. LED strip or Pixel chains work fine as long as you have either WS2801 or LPD8806 or LPD6803 IC's in you LEDs. Install Python and Git on your raspberry pi (via apt-get). These are the python libraries i have installed, some may already be installed on your Pi, can't remember which ones were 100% required. I also have RPi.GPIO-0.4.0a installed (I had to download it and build it from source - you may find the raspbian package works but it stopped working for me after I did an apt-get upgrade on my pi, grr.
Download my code from github (or fork it and download your own fork): git clone cd PixelPigit checkout ambipi Then for the XBMC side of things...
