Hi so I'm pretty new to arduino but I think you could add this code to work also

#define IDLE 0
#define INFLATING 1
#define DEFLATING 2

#define OFF false
#define ON true

byte state = IDLE ;

void start_inflation ()
{
  state = INFLATING ;
  motor_control (ON) ;
}

void start_deflation ()
{
  state = DEFLATING ;
  motor_control (OFF) ;
  deflate_valve_control (ON) ;
}

void stop_deflation ()
{
  state = IDLE ;
  deflate_valve_control (OFF) ;
}

void loop ()
{
  switch (state)
  {
  case IDLE:
    if (start_button_active ())
      start_inflation () ;
    break ;
  case INFLATING:
    if (read_pressure () > MAX_PRESSURE_LIMIT)
      start_deflation () ;
    break ;
  case DEFLATING:
    if (read_pressure () < MIN_PRESSURE_LIMIT)
      stop_deflation () ;
    break ;
  }

}

P.S for the experts out there, tell me if there's an error

Not an error, but my preference for state change would be to have it in the switch statement, not in the functions called from the switch statement. IMO that would make the state machine easier to read, without having to go and check the functions called from it.

Why no stop_inflation();? That would cause a race condition between indlation and deflation.

Where are these functions?

What does this code have to do with the original post?

Do not hijack topics. Start your own topic.

I’m sorry.
I’m pretty new to coding and arduino but thank you for telling me!

Hi, I want to make a 6V dc motor that is powered based on the pressure input by the pressure sensor.

Also I want to include an LCD display that shows the pressure input by MPa unit.
Thank you.
