Finally got the #LCD panel working on my #arduino project

In my last post I showed the pin outs for the LCD as provided by the seller. One pin #3, I didn't connect it to anything because the diagram showed a value of "--" and I took this to mean it wasn't required. When I couldn't get even a flicker, I started to play around eventually connecting it to ground and, amazingly, the screen lit up. It was all black though, so I figured that I need to reduce the current. I tried several different resisters and settled on a 20 k which gave me a tolerable contrast. In the end, I guess that I need a variable resister to get it exactly right. Now, I can start coding the rest of the game logic. This is gonna be fun.
