Une fois le script lancé, celui-ci jour une mélodie toutes les heures et toutes les demi-heures. Il faut donc être patient pour le voir fonctionner.
Après la mélodie horaire, le buzzer effectue un nombre de "beep" correspondant à l'heure signalée.
Le script en cours d'activité affiche également des messages toutes les 5 secondes dans la session REPL:
