Blink LED Async
- Async - no delay
Call the routine blink() often in main loop, it will check i 1 second has passed and change led on pin ledPin
void blink() {
static boolean blinkLed;
static unsigned long Blinktime;
const int ledPin = 13;
const int delayMsec = 1000;
pinMode(ledPin, OUTPUT);
if ( millis() > Blinktime ) {
if (blinkLed) { digitalWrite(ledPin, HIGH); }
else { digitalWrite(ledPin, LOW); }
blinkLed = !blinkLed;
Blinktime = millis() + delayMsec;
Serial.println();
Serial.print("Blink.");Serial.print(blinkLed);
Serial.println();
};
}...
