AttinyRGB

Sorry about the delay, I've been busy for these past few weeks with various activities including configuring a new laptop. Anyways I got a chance this afternoon to take a video of it. Sorry about it not exactly being 1080p but I don't own any "newish" camcorders (the one I used was a hand-me-down from a relative.) I will probably do another video next week from a better angle, the video sadly comes nowhere close to doing it justice.

Let me start off by first saying that this project didn't exactly originate a few days ago, it actually started last year around Christmas when I wanted to find a way to give some light to a Nativity scene. I came up with lighting it with an RGB LED. I whipped something up under the Arduino IDE that would rotate between colors. It looked nice, but I later decided to make the transitions between colors smooth, so I made a second, much improved revision.

When I read about the HaD 1 kB challenge, I remembered my neat RGB LED transition program and knew that I could easily redo it under AVR-GCC to get it well below 1 kB. The one that I did (second revision) under the Arduino compiled to 1,402 KB. Under AVR-GCC toolchain I've gotten it as of this writing to 464 byes, way under the 1 kB limit.

I will most certainly be making some more changes and improvments.
