#116303 - a slight problem Responding to: ???'s previous message |
schematic taken from http://www.disall.narod.ru/
while that allow any LED to be selected, I know of no application where the issue is not any combination of LEDs This schematic seems to be more an academic excersize than anything useful. Erik |
