Thanks for the links everyone.
An arduino or basic stamp all seem like probably a bit overkill for what I'd like to do.
I want to drive 6 four-lead multi-color LEDs that each draw 20mA. They all have to be controlled independently of each other. So, I should have a total current draw of 120mA, yes?
Unfortunately, I'm not sure of how to tell whether a specific chip supports it. Those PICs are looking pretty nice and cost-effective, but I can't determine which model I need.
Edit:
Apparently I missed checking out the spec-sheet on the Parallax Propeller last night.
According to the data sheet
here it looks like (unless I'm reading it wrong) that the chip can put out 40mA per I/O and a total of 300mA?
Am I reading that right?
