PROJECT 4: Rangkaian Sederhana N-Mosfet

 Rakit rangkaian seperti gambar berikut:

SKETCH YANG PERLU DIKETIK:

int sma_pin=5;
int led_pin = 13;
int dt = 100;

int sma_pwm=90;
int T = 2000; 
int on_time = 0.25*T, t = 0;

void setup() {
  Serial.begin(9600);
  pinMode(led_pin, OUTPUT);
  Serial.print("on_time = ");  
  Serial.print(on_time);  
  Serial.println(" (ms)");
}

void loop() {
  if (0 <= t && t < on_time) {
    analogWrite(sma_pin, sma_pwm);
    digitalWrite(led_pin, HIGH);  
  } 
  else {
    analogWrite(sma_pin, 0);
    digitalWrite(led_pin, LOW);  
  }
    
 delay(dt);
 t += dt;
 if (t >= T) t = 0;
   Serial.println(t);
}
