Arduino Nokia 5110 LCD Tutorial #2 - Getting Text on the Display
Another function is needed to write data to the Nokia 5110 display. Also a font (a 2 dimensional array) must be included. Additional functions are required to send strings of characters.
I also look briefly at sending X and Y address location commands so that text can be positioned anywhere on the display.
It appears you can't put curly brackets in the video description, so I've put the code listing and font data in the comments below."
