The average voltage (average power) of PWM signal depend on the duty cycle: Vavg = 3.3V * Th / T

La tension moyenne (puissance moyenne) du signal PWM dépend du cycle utile: Vavg = 3.3V * Th / T ou encore Vavg = 3.3V * duty_percent / 100

Obviously, a 0% duty cyle is equivalent to a LOW signal whereas a 100% duty cycle is a HIGH signal.  

Evidement, un cycle utile de 0% est équivalent à un signal BAS tandis qu'un cycle utile à 100% correspond à un signal haut.  

In the following example, we will use PWM to dim the light on the onbloard LED.
