Perhaps I've had too many beers, but here's the situation...
RA4 ---+
LED (D1)
RA5 ---+
LED (D5)
RA2 ---+
LED (D7)
RA1 ---+
Setting RA1 to HI, and RA2, 5, and 4 to LO, should, in theory, pass current through all the LEDs?
I see what you're saying about setting pins to Input to 'disable' them, but if i wanted them all to light, is it simply the consumption of each LED stopping the next to light?
I think we've already decided this, but would like to be sure.
Also, why the big pull away from 'current'? surely they're eating up the current rather than the voltage? true, it's been a while since I did electronics like this, bit of a refresher course would be nice.
Thanks for all the info and help, I thought it was cos of the current/voltage that was stopping further LEDs from lighting, just been looking for the clarification.
Very much appreciated... I'll have a space-rocket built in days at this rate!
