Ok, krilos. Solo anadi el else a tu if principal y ya esta funcionando en mi arduino como tu quieres.
Aqui te dejo el codigo. Cualquier duda o problema, solo hazlo saber. Saludos.
int pulsador = 2;
int led = 9; // the pin that the LED is attached to
int brightness = 0; // how bright the LED is
int fadeAmount = 5; // how many points to fade the LED by
// the setup routine runs once when you press reset:
void setup() {
// declare pin 9 to be an output:
pinMode(led, OUTPUT);
pinMode(pulsador, INPUT);
}
// the loop routine runs over and over again forever:
void loop() {
// set the brightness of pin 9:
if (digitalRead(pulsador) == HIGH)
{
digitalWrite(led, HIGH);
delay(300);
digitalWrite(led,LOW);
delay(300);
}
else
{
analogWrite(led, brightness);
// change the brightness for next time through the loop:
brightness = brightness + fadeAmount;
// reverse the direction of the fading at the ends of the fade:
if (brightness == 0 || brightness == 255) {
fadeAmount = -fadeAmount ;
}
// wait for 30 milliseconds to see the dimming effect
delay(30);
}
}
