/* FabAcademy 2023 -Emma Pareschi
In this skect the brithness of the led goes from 0 to the max intensity.
With this sketch you learn about analogWrite and 'for loop'
*/

int led_pin = 3; //define variable for the led pin

// the setup routine runs once when you press reset:
void setup() {
  // declare pin 9 to be an output:
  pinMode(led_pin, OUTPUT); //set the led_pin as output
  Serial.begin(9600);
}

// the loop routine runs over and over again forever:
void loop() {
  
  for (int i = 0; i <= 255; i++) {
    analogWrite(led_pin, i);
    delay(10);
      Serial.println(i);
