Hardware debuging

Ran in to some problems with the garage door opener project. I swapped the four button epoxy keypad with a "real" one with 0-9 , "*" and "#". I took precautions for voltage drop over the longer lead, but it still didn't work every time. The relay doesn't connect for 1000 millisecs like the code says, WTF? I think it must be an issue with the power supply, so I beefed it up a bit, and I am testing it now. Hope it works tomorrow morning, after a cold night.
