So basically, I'm trying to make a digital wall clock and using digital numbers, I have 7 sections of LED's per number, 4 numbers and one section for the colon in between them. A total of 30 sections. The colon will toggle every second so the the most possible simultaneously glowing sections is 27. That's because of the time 08:08. Is there any way to make this work with an arduino? Possibly by Charlieplexing the arduino into 30 sections, using 6 pins. Or is there something out there that has 30 pins!?
The problem of course with charlieplexing, is that you need it to become rapid pulses. I'm sure I'm going to need some help with this, and also with laying out a schematic.
