I have 12 LEDs that I want to turn on/off in this order:
Each one will be on for a period of time before shutting off.
1 on
2 on
1 off / 3 on
2 off / 4 on
3 off / 5 on
4 off / 6 on
5 off / 7 on
6 off / 8 on
7 off / 9 on
8 off /10 on
9 off / 11 on
10 off / 12 on
11 off
12 off
I think a MCU would be best for this but is there something I can do in the analog domain? I was thinking a couple of 555 timers but then my part count is getting high. Thoughts?
