Hi, I managed to interface a 16x2 LCD. But I seemed to be lucky only once as I saw the msg on LCD only once, after that Im unable to see any msgs instead i see only special characters on the screen. please help me out.

Whatever you did the first time, you probably should do it again.

Sorry... I couldn't resist myself. There are lots of us who will provide help, but you really will have to provide more information before we can help you.

when i did my first lcd it was because of loose connections.

did you solder the wires to the lcd? I used female connectors, so that is why it was flickering.

Wiring it as above seems to help. In particular ground the 5th pin on the Panel and don't wire it to the arduino. It helped on here :
