Hi all, I'm just starting out but am kind of confused by some basic behaviour i'm seeing with the Arduino Uno board I have. I'm sure it's fairly elementary to others. My first sketch is this: NettetdigitalWrite(LED_BUILTIN, HIGH); This supplies 5 volts to the LED anode. That creates a voltage difference across the pins of the LED, and lights it up. Then you turn it off with the line: digitalWrite(LED_BUILTIN, LOW); That takes the LED_BUILTIN pin back to 0 volts, and turns the LED off.
