Building a UI with different Menus and Submenus on Arduino

[Dave_Lowther]

The approach I followed uses nested while cycles (set to true) to wait the button to be pressed. When one of the buttons is pressed, an if statement detects that, leading into another while-true loop

You could use a state machine, at least to remember which top level menu has been selected. Although if you are only going to have 2 top level menus (timer, stopwatch), you would only need a bool to tell you which menu you are in. Nested While(true) loops doesn't sound like a good method
