Eine LED Anzeige mit 6 LEDs, die mit 2 Buttons gesteuert werden kann. Durch drücken beider Buttons, wird der Modus zwischen Aufbau/Helligkeit gewechselt. Der aktuelle Modus wird durch die 2 Status LED's angezeigt. Wird die Klasse "debugfunction" im Loop aufgerufen, werden die Werte über die Schnittstelle ausgegeben.
Code:

#define PWM2 10
#define PWM3 9
#define PWM4 6
#define PWM5 5
#define PWM6 3
#define MODELIGHT 12
