3 Channel PWM Controller

This is a basic design for a 3-channel PWM controller, like you might use to control a string of 12v RGB LEDs, like these, maybe:

I've got a few different things I want to do with this, but it was mainly a way for me to try designing and etching my first PCB.

FEATURES:
* Custom Arudino bootloader (kinda)
* Three 200ma(ea) 12v PWM channels
* Three analog input pins
* Runs on 12v (good for use in a car!)
* Minimal part count
* Simple


WIP WHY:
* All the photos are of the first design, which as you can see, had a lot of mistakes requiring jumpering and trace-cutting. I think they have all been solved in the uploaded schematic, but I haven't had an opportunity to print a new one to test.
* The first design schematics are lost, sorry. :(
* I'm using a custom arduino bootloader (will be provi
