WebMar 9, 2024 · In the main loop, you turn the LED on with the line: digitalWrite(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.
