Hi,
Perhaps you could clear one part up for me then. I'm not sure how one line works.
unsigned long currentMillis = millis();
if(currentMillis - previousMillis > interval) {
// save the last time you blinked the LED
previousMillis = currentMillis;
// if the LED is off turn it on and vice-versa:
if (ledState == LOW)
ledState = HIGH;
else
ledState = LOW;
// set the LED with the ledState of the variable:
digitalWrite(ledPin, ledState);
}
}
"unsigned long currentMillis = millis();"
unsigned long is a variable, currentMillis is the name of that variable. I get that much. but when you = it to millis(), doesn't that mean your setting currentMillis as a clock that keeps on counting till the counter maxes out and resets?
Then your saying if currentMillis (the counter that keeps on counting) - (minus) previousMillis (which was set to zero), is greater than interval (1000ms) then:
reset curentMillis to previousMillis which equals 0. So how can you reset currentMillis to 0 if currentMillis = millis().
I'll keep playing in the meantime
Thanks again
