Onboard LED

The Nucleo-C031C6 has an onboard user LED (LD4), attached to GPIO pin PA5 (D13). The LED is lit when the pin is driven high.

You can also use the LED_BUILTIN constant to reference the LED in your Arduino code:

pinMode(LED_BUILTIN, OUTPUT);
digitalWrite(LED_BUILTIN, HIGH);

See Blink for a complete code example.
