Jiří Lexa - časové sepnutí bez delay

// cislo 5 jsou sekundy za kolik to ma sepnout
uint16_t X = 5 * 1000;
unsigned long oldMillis=0;

void setup() {
  pinMode(13, OUTPUT);  //dioda
  pinMode(12, OUTPUT);  //rele
  pinMode(10, INPUT_PULLUP);   //cidlo
}

void loop() {
  if (digitalRead(10) == LOW)
  { //kdyz neni signal z cidla - zapni rele (az po X sekundach)
    if (oldMillis+X <= millis())
    {
      digitalWrite(13, HIGH);
      digitalWrite(12, HIGH);
    }
  }
  else
  { //kdyz dojde signal z cidla vypni rele hned!
    oldMillis=millis();
    digitalWrite(13, LOW);
    digitalWrite(12, LOW);
  }
  //delay (1000); DELAY SUCKS!!!
