pinMode(13, OUTPUT);

void setup() { pinMode(13, OUTPUT); digitalWrite(13, LOW); delay(5000);

LOW

digitalWrite(13, HIGH);

digitalWrite(13, LOW);

void setup() { pinMode(13, OUTPUT); digitalWrite(13, LOW); delay(5000);

}

5000 ms = 5s

void loop() { digitalWrite(13, HIGH);

}

Restart? RESET!

Step 2 – usable Timer

Sketch

void setup() { pinMode(13, OUTPUT);

pinMode(7, INPUT); }

pinMode(7, INPUT);

void loop() { val = digitalRead(7);

if (val == HIGH) { digitalWrite(13, HIGH); delay(5000); } else { digitalWrite(13, LOW); }}

Step 3 – variable Timer

Sketch

void loop() {

t0 = analogRead(A0); …

delay(t0);

}

Step 4 – alarm Timer
