i'm stuck with a little problem. I need to create a program that can store a number via keypad (this number will be chosen by the user) and then do something with it. To be more specific i will create a temperature control in which the user will be able to input a value of temperature they need and then with this value control a heater, but that's another story, the main point here is that the program needs to be able to store a value via keypad.
i use the keypad library and some of its commands like getKey() and waitForKey() and so on.
thanks for your answers!
