The easiest way of doing this is with a switch statement

Code:

switch (state)
{
  case 0:
    if (button_pressed)
    {
      count += (count < 100);
      if (count == 100)
      {
        count = 0;
        state = 1;
      }
      else if (count > 100)
      {
        count = 0;
      }
    }
    else
    {
      count = 0;
    }

    break;

  case 1:
    if (!button_pressed)
    {
      count += (count < 100);
      if (count == 100)
      {
        count = 0;
        state = 0;
      }
    }
    else
    {
      count = 0;
    }

    break;
    
}

Also noticed that I do not take the reading straight away -> I wait for 100 positive readings in a row before I change state.
