Arduino LCD

June 10, 2009 Comments off

So today I finally got a dot matrix LCD module from Dick Smiths (Z4172) and proceeded to wire it to the Arduino. Ended up working out pretty good although the USB was struggling to run the Arduino + Ethernet Shield + LCD (the LCD contrast was dull even with the 10k pot wound right up). No biggie, I just pulled the Ethernet Shield off and went directly to the Arduino. It will probably be used almost exclusively on one computer so I think I will just control it via the USB serial port.

One thing I could not work out was why the screen would not work if I was using digital pin 1 for one of the connections. I ended up using from 2 to 8 which still allows me to use it with the Ethernet Shield should I want a networked little display! My initialisation line was LiquidCrystal lcd(2, 3, 4, 5, 6, 7, 8);

Check out some pictures of it below (extra points if you can work out where the quote on the screen is from without using Google!):
