There are 5 push buttons each which correspond to a certain pin let us use 1 to 5 for an example. I want to set a variable, ActiveButton which will be set equal to the the only pin in the one state.
We make use of the concept that there can only be one active push button which means the pin of that would have a state of 1 and the rest would be 0. The long method for this would be to use if else and digitalRead(pin) == 1 for everything but that would be so long on code. I've considered using do while or while loops to stop until it reaches the push button with a state of 1, but I was wondering if there was a more efficient code. I was also thinking if there was something that made use of an array?
Though the idea of like having a simple array return the index which results to a corresponding value, like lets say Array ==1 among all the indices from 0 to 4 feels easy to conceptualize, I believe this can be really taxing on the code and might not be able to be done in a short way.
I've also thought of possibly using switch case, where the variable would be the high state and the case values would be the digitalRead for each pin? But that would be wrong probably because I'm not sure but you can't set the switch variable to be a constant. It would be something like
