There is many interesting things about Nokia 3310 LCD: low price, easy to interface via SPI port, can support graphic and text and low current usage.

So you got your ATMega board, got your environment set up and got the LED to blink... WhooHoo baby step, now you want to get serious. The first thing I wanted to be able to do was to actually see some output to be able not only see certain values but to help me debug the applications that I will be creating.
