PWM Motor Control

PWM Motor Code

This code makes the motor speed up until it reaches the highest speed possible and then it resets to low speed again.

------------------------

int motor = 9;
int speed = 0;

void setup() {
  pinMode(motor, OUTPUT);
}

void loop() {
  analogWrite(motor, speed);

  speed = speed + 31;
  
  if (speed > 250)
  { 
    speed = 255;
  }

  delay(4000);
  
  if (speed > 250)
  { 
    speed = 0;
  }

}
