So I'm controlling a fan with a solenoid. Why? The fan manufacturer put in soft PWM fades when changing speeds. I didn't want to rip the fan apart for a better solution, so I decided to use a small solenoid to press the buttons.

The fan switch has 9 positions, starting at OFF and going up to HIGHEST.

My question is, is there a better way to code this? What I have is working, but I think I might could learn something here.

See below:

//Temperature conditions, speed 1 is off, 9 is highest
buttonpresses=0;
  if (board1temp==0){   //this is for startup, while waiting for data
buttonpresses=0;
 }

if (board1temp > 79){
  newspeed=8;
  buttonpresses = newspeed-oldspeed;
  }

if (board1temp <78 && (board1temp != 0)){
    newspeed=2;
  if (oldspeed==newspeed){
    buttonpresses=0;
  }
  if (oldspeed<2){
    buttonpresses = 1;
  }
  else if (oldspeed>7){
    buttonpresses = 3;
  }
 }
