Ladies and Gentlemen, some advice please.
I am trying to develop Arduino based Hardware/Software solution to the following problem: adjusting the brightness levels of 2 separate arrays of LEDs with the following parameters:
-all of the LEDs must share the same 2 bus conductors. -one group of LEDs will be wired with reverse polarity. -the LEDs must appear to be constantly on. -the brightness level of the 2 groups of LEDs must be adjustable, something like a "pause-able cross-fade"
any advise is greatly appreciated.
