Oh, and I'll also be buying all the stuff necessary the next day. This. Looks. Awesome.

How much does one of those cost?

Forget the nonsense about playing with timers -- most PICS / AVRs have hardware PWM peripherals that can be simply setup and then varied by writing to a single register. The change is immediate -- certainly faster than writing to a digipot via SPI or I2C. I realize I’m commenting on an old post — but PWM would be much easier.

Just one or two things I'd like to ask. In the break up and description of the schematic, there are two parts that are never mentioned. One is where is ARD-5v-g-strike going and what is it? The other is, what is the value of R15? There are 14 resistors in the parts list, 15 in the schematic. Am I not reading something? A great project! Just one or two things I’d like to ask.

PWM requires fairly tight timing to get the colors to play nicely, which means your processor needs to spend it’s time playing timer on so many levels.

I like the idea of randomly changing the colors…if it’s not actively being used to unlock a door (or command some other system ;-), then I think it should be Blinky Light Art.

Clever hacks! I’d still add the blocking diode at the relay, since I’m Old School, and I used to play with bigger coils with lots of energy.
