Cant get 2 analog input readouts correctly

[anon73444976]

@jwut

Serial.setTimeout(10000);
  pinMode(A3, INPUT_PULLUP); // sensor 0
  pinMode(A4, INPUT_PULLUP); // sensor 1

Why with pullups?

void main_loop(){

That's new to me

void braker_state_check(int *which_sensor){
. . .
braker_state_check(1);

Not very pointer-like
