Hi everyone!
I'm new to arduino. I tried to both google and search the forum, but could not find answer. I know this is so basic, but I have to ask this anyway: Is it normal to have a short circuit between the VDD and VSS or V0 pins?
I bought a cheap starter kit of from ebay and it did not have pin header strips included. I tried to solder temporary legs to get display attached to breadboard. Before plugging the power I tested my work with a multimeter. At first VDD and V0 pins had a short circuit between them, but not between VDD and VSS. After taking a bit of solder away with a tinsucker I noticed that the short circuit was now between VDD and VSS pins, but not between VDD and V0. I tried to fix my work many times, but the short circuit stays all the time even while it sometimes switches back to the earlier combination.
I read somewhere from Google that this could be due to uncharge some capacitors on a LCD circuit, but could not be sure. My sight is not so good either, so I might actually have some mysterious hair on my circuit that causes the problem or I might have fried my LCD-board somehow while soldering those temporary pins to it. I did not want to plug it in and risk my other equipment while being unsure if the short circuit is actually intentional or not.
Could you help me with it: Should I just order a new LCD with pin header strip included, or could I still salvage this one just by soldering pins again more carefully, or is it just normal behaviour of a LCD?
