Control a DC motor speed with Arduino and a MOSFET - Three speeds
const int motorpin = 5;
const int divider = 3;
int motor_speed = 0;
void setup()
{
Serial.begin(57600);
pinMode(motorpin, OUTPUT);
}
void loop()
{
for(motor_speed = 0; motor_speed <= 255; motor_speed += (int)(255/divider))
{
printSpeed(motor_speed);
analogWrite(motorpin, motor_speed);
delay(5000);
}
}
void printSpeed(int motor_speed)
{
Serial.print("Current Speed: ");
Serial.println(motor_speed);
}
