=== LEDs and errors ===
Being able to understand rapidly what's happening inside your object is essential to fix the issue.
The best is to figure out what's happening is to use LED, blink status, heartbeat.
By doing so, no need to open a Serial Monitor or diagnostic tool to figure out the status of the objet.

The NeoPixel LED does turn GREEN when the Feather M0 switch on to normal operation (when it runs your Arduino Sketch).
In the following sample, we do take the control over the NeoPixel LED to switch it off at the end of {{fname|setup()}} function. This means that all buses and devices are properly initialized.
The RADIO_LED wired on the Pin 13 is used to signal radio status when emitting a message.
