Hi everyone. I was thinking about a nice project that would be interesting to develop: a LED clock. Here's how I imagine it (roughly):
I was wondering if there's a multiplexer huge enough to handle, let's say: - 1 LED / second = 60 LEDs - 2 extra LEDs / 5 minutes mark = 24 LEDs - 4 digits, 9 LEDs high * 5 LEDs width = 27 LEDs - 1 comma = 2 LEDs Total: roughly 110 LEDs... So I need a 7bits multiplexer? a 128++ pins monster? Does it exist?
