How to drive a lot of LEDs from a few microcontroller pins.
How to drive a lot of LEDs from a few microcontroller pins. - More DIY How To Projects]]> westfw Using the fact that many microcontroller pins have three states (+V, GND, or"high impedence", you can drive N*(N-1) LEDs from N pins. So the little 8pin microcontroller like a PIC12Fxxx or an ATtiny11 can drive 20 LEDs onits five available output pins, and still have one pin left for some kind of i...
