I was wondering if anyone here had an idea on how to write a code to allow you type words and numbers to serial with a 3x4 keypad.
You know like old cell phones where you had to press key  3 times to get the letter C, or key  for spacing?
I would like to find a way how to do that but I no idea on how to even start lol
I would like to output that to my liquid crystal display I have here.
Any help please?
