  • Is pin 3 really a ground? If I follow my MM it lines up with the +12V which isn't making sense to me.

  • Thanks for the reply. I don't really understand the schematics but I'll give it a shot. I'm looking at JP2 and I'm guessing this is where I put my 5V source? Does the fact that I don't have a CTL matter? I'm guessing that would be my trigger to turn the relay on? Actually, could you walk me through the schematic? I have questions pretty much all the way through, for example, what is the purpose of all the resistors? I understand the 330 but not the 10k or 150.

  • This is going to sound like a stupid comment but I'm just learning this stuff. Where are the instructions? I think I figured most of it out from the picture but my LED won't light up so I'm wondering if I have it backwards and minor stuff like that. Can anyone help me out? I'm also wondering some other things.

No public wish lists :(
