I've got a 12f683 and want to run 16 LEDs off it. I want one LED to be on for about 2 seconds then move on to the next. What is the easiest and cheapest way to hook them up?
I'd swear I saw an article that the maximum number of LEDs one could hook to a PIC was defined by 2 raised to the number of pins available. That would mean a 12f683 is capable of controlling 64 LEDs (2 to the 6th).
Is that true?
