Buttons to start different loops

Projects General Guidance

Thanks for this i can get it to start the loop but it wont switch to the other loop when the other button is pressed

model 2 does. Did you implement the 3 models and compared their behaviour?

You can also implement a state machine which holds a variable telling which loop to run, that is affected by the buttons pressed.

int whichLoop = 0;

void loop()
{
  // CHECK THE BUTTONS
  whichLoop = 0;
  if (digitalRead(PIN_A) == HIGH) whichLoop = 1;
  if (digitalRead(PIN_B) == HIGH) whichLoop = 2; 
  if (digitalRead(PIN_C) == HIGH) whichLoop = 3;

  // SELECT THE LOOP
  switch(whichLoop)
  {
  case 1: loopA(); break;
  case 2: loopB(); break;
  case 3: loopC(); break;
  default: break;
  }
}

void loopA()
{
  // do you A thingie
}

void loopB()
{
  // do your B thingie
}

void loopC()
{
  // do your C thingie
}
