Great instructions made for an easy build. Still working out how to set different currents for different voltages. Is there an equation for how to set if to get different currents. I know the video said 1V = 1 Amp. I guess that means 0.5V = 500ma. If I decrease the value of the pot can I get finer adjustments? Seems easy to draw a lot of current by accident with the 500k pot. Set it too high once and the resistor started to glow orange. Cut the power quick and it seems everything survived my mistake.

I have a common anode display that I would like to use instead. What would I have to do with the code to allow for that? I figure everything would have to be inverted, but I'm fairly new to programming attiny's. I'm not exactly sure what code needs to change.
