Ok so I have one rigged up in my car just to test it, not to much to add but here is a video of it. I will be using 3 atmega’s to run them, since I need hardware spi and there is only one per atmega, so 2 to run the lights and one more to receive commands to change modes.
Also I am using one resonator to run both megas that are running the lights so when in ‘car show’ mode they will stay in sync with each other.
Just wanted to throw this up here. Been working on some RGB LED turn signals for my car (2008 Mustang GT/CS)
I’m using the Adafruit pixels http://www.adafruit.com/products/307 for them, there are 35 in each light.
Why you may ask? First off why not! Second I take my car to car shows and just like to have somethingunique that I made myself. Third I had bought some LED bulbs that were advertised to match the stock headlights in color but they are far from it, they ended up very blue like a typical white LED, I was guessing they used warm whites but I was wrong so after making some tail lights for my dads car I figured why not do the same to mine.
Anyways here is a video that give info and how they look, I’ll post more as they come along. (Picture of car at end of video!)
Here are the ones in my dads car, they use two 8×8 matrices run by one atmega and two MAX7219′s in each lite, so that 128 leds a light and individually controllable. Also a remote to turn them on into ‘Car Show’ mode.
