Can someone help with this. I know it's trivial but I am not quite sure how to do it. I want to use the Arduino a MC1413 darlington array. The output of the Darlington array will swith on the relay (relay draws 200 ma so can't use it directly from an Arduino). Can anyone help me set the Adruino, MC1413, and standard reed relay up?

Connect MC1413 pin 1 to the arduino digital pin, MC1413 pins 16 to one side of the relay coil and pin 9 to the other side with is also connected to the positive side of your power supply (whatever is proving the 200ma for the relay). If your reed relay coil is intended for 5 volts you can use the 5v Arduino pin for power.
