Automatic Garage Door Closer

retrolefty:
Yes, 90ma is too much to draw from a output pin. Either use a switching transistor with the existing relay or use the lower current relay. Output pin current should be limited to 20-30ma maximum current draw.

Thanks. Switching to the other relay instead. Hopefully, RadioShack will let me return that other one if I can find the receipt.

Also, I just checked the garage door opener, and it's only showing ~35 mA when the 2 pins are shorted to operate the door, so no worries there.
