ok, this is getting pretty stupid now.
ive changed the transistors on the anodes for the uln2803 and put current limiting resistors on the cathodes...
this chip has just taken most of the electronics out of it!
i still cannot get any of the lights to light up whatsoever...
well, i lie, if i touch one of the leds bases, then they light up a tiny bit, so i think that means that there is some power going to the leds, and that its the grounding thats causing the issue.
on a side note, is there a site that shows just the arduinos mathmatical formulas.
i can get my head around
for(int i = 0; i<8; i++)
i just don't get the ++ part. i know that's what it needs to add calculations, but i haven't found it explained anywhere.
thanks!
