Hello,
A question about looping inside a switch case scenario.
I saw some tutorials and topics on this and other forums about it but it just couldn’t work.
Idea: I have 1 button that I want to use to go through a switch case menu.
Only when I press the button, the next case in the switch has to loop,
until then I want the case itself to loop.
In this code, the switch runs through it until it reaches the last one and stops there.
I tried some if / else if statements, one button menu’s and other ideas but I’m lost.
In the code I only display the first case, the second and further cases are copies.
Goal: Use the switch case to receive a signal, display a measurement every 1 / 2 secs,
and Most importantly: - I want to loop through custom buzzer and led signals. -
The custom ‘receiving signals’ are quite simple but I don’t know how to isolate just that and keep the rest the same…
Greets!
