frank1293:
i get you, so what are you trying to say? that if i work out whether im using a character or a number im able to 'concatenate' so to speak.. because through the keypad.h library when i return the keypad number 1, it returns 1 as a char, however if i store it as a integer it returns 49, which is ASCII im assuming?
Yes, it is ASCII.
What I am trying to do is show you how to convert characters, and pairs of characters, into the numeric values that it seems you are after.
What are you really trying to do?
