hi
i am trying to make a boarduino
i have already BIT BANG the IC with my other arduino and uploaded a simple blink code and it worked fine.
but when i put all in a breadboard its not working
a bit hard to see what's going on
do you have a schematic picture?
also take a look at the resistor that is probably the current limiter for the LED in the top right corner
seems to me it is connected between ground and 5 volts!
