I try and see prices because to me bit-bang for the buck is a concern.

You can fit 3 Tiny85's on a 24-pin socket but even disabling reset you only have 6 pins free each.

The Tiny44's start with 14 pins. You might double the usable pins for less than 2x the $.


I find it harder to express logic in English than in Code.
Sometimes an example says more than many times as many words.

How about WS2801 per strip, or one for every 3 strips?

That is EXACTLY what I was looking for! :D
Does 3 LEDs, and can drive a transistor, also available for £0.30 ea inc shipping :D

Your help is VERY much appreciated.
