Hi there, sorry for my terrible English, but i do have a little problem: I use Arduino MEGA and W5100 to control 25 relays(OMRON G5LA 5VDC). But it seems too many relays made my voltage drop down. And when voltage drop down, my W5100 doesn't work properly. I use a 220VAC-->5VDC 20A regulator, but t…

Too many relays cause voltage drop?

Does anyone has some ideas how to solve voltage drop down?

The arduno tutorial pages should have schematics showing how to control a relay using a transistor.
