// This is the correct pin on the Raspberry Pico board. On other boards, even if they have an
// on-board LED, it might need to be changed.
// Notably, on the Pico W, the LED is not connected to any of the RP2040 GPIOs. If you have
// a Pico W and want to toggle a LED with a simple GPIO output pin, you can connect an external
// LED to one of the GPIO pins, and reference that pin here.
