I have been learning a lot lately. Using perf board(should have used strip board!) boards with a sanguino is a pain and is hair ripping. I used female headers, the sanguino plugs into it and I'm finally done with.
Then I just figured out stranded wire is a pain to use when your trying to wire up a 20X4 LCD, I've used it a ton of times with my bread board and it was working wired but I think I pulled a pad, but I'm not totally sure. The contrast bars are showing, however no text is showing. I was removing the wires then soldering on longer ones, I'm ready to remove them all and redo it all. Should I use solid wire for this? Could I have killed my LCD by using a 2.7K resistor from the LCD's contrast set to ground? (That's what I've been using since I broke my 10K potentiometer. The contrast is perfect so I'm thinking it's not messed up)
If I pulled a pad should I very lightly sand the solder masked trace since I probably pulled my pad, then solder on a thin gauge of wire to it, finally then solder it(the small thin jumper wire from the trace) to the wire that's in the hole?
Sorry for the question, I've spent a few hours monkeying with it and getting close to tossing the LCD then try again since I'm questioning everything I've done.
