I want to write a code that will ask a user yes or no questions. They will use push buttons to answer yes or no and the questions will be displayed on an LCD screen. What I was thinking of doing was having a variable with a certain value. Every question will affect the value of this variable. And if the variable is a above a certain number it will display a message. It is sort of like a game show I suppose? Now I'm not exactly sure where to start. I have no idea how to change and store the value of a variable. Also how do I make my arduino wait until a button is pushed. I don't know I'm so confused. Can anyone help me get started?
From the sounds of it you should also read about progmem and storing string into it and retrieving
