I know there is a lot of charlieplexing tutorials out there but non of them are very suitable for my case. I want to charlieplex 4 ledstrips together and control them by an arduino. This means that i need a seperate powersupply and use some mosfets to control the inputs. However I can't think of a way to implement that in my current scheme. I'm very new to all this so I could just not know something that is possible so that's why I'm asking here.
Does anyone know a way to do this? Thanks in advance, Stijn
