I am a novice in electronics so small word replies please
I am (to prove I can) trying to make 8 LEDs turn on/off in sequence (similar to the ones on the front of KITT for those who remember Knight Rider). I have a 28x1 project board (so with the octal darlington on it).
The simulator software suggests I have my program right, but when I connect it all up the LEDs do not light up, and the battery pack gets very hot! Short circuit somewhere??
I have a V+ feed from the output pins by the darlington going to my breadboard, and that is the +ve for the LEDs. The -ve side of LEDs goes to the output pins (as I know the darlington is a power sink (or whatever it should be called).
Any ideas what I am doing wrong?
