Hi,

i saw that the Mega can handle around 1A with 7 volts.
If i look how many I/O we have and if i think about adding some shields,
then maybe it's not much.
I figured out how to feed 1Wire stuff with an extra supply.
I also see allot about on how to do it for servos.
But how to do it for the other stuff like LEDs from optocouplers?
