Essayez de déplacer le fil que vous avez branché sur D7 de la masse (GND) à 5 Volts. Vous devriez voir les lectures de la valeur d'entrée passer à 'HIGH' (niveau haut):

 

Try moving the jumper wire for D7 from ground to 5 volts. You should see the input start to read a high value:

Swap the jumper wire between ground and 5 volts to see the input value change.

Basculez de nouveau le fil de +5Volts vers la masse (GND) et la valeur lue repassera de nouveau vers 'LOW' (niveau bas).

 

Let's look a little more closely at the code to understand how reading and writing digital GPIO works.
