I'm considering a project where I might run 40 mA relays on all 14 of my arudino's I/O ports. Anyone try this before? Might this be a very bad idea? Taking this question further, if I bought the new Arduino Mega (with the 54 I/O ports) and ran 54 mA relays, do you think the board would be able to r…

Maximum Arduino Milliamps?
