Bonjour, J'ai recu des cartes (Clone) Arduino Nano V3.1, et j'ai plusieurs problèmes :
Problème n°1 : avec mon moniteur série, il m'affiche des caractère incompréhensible
Problème n°2 : montage avec une carte RFID
Le téléversement se passe sans soucis, mais cela ne fonctionne pas.
La L clignote très lentement, et le badge n'est pas lu.
J'ai essayé avec une autre carte que je possédait déjà, et ca fonctionne sans problème avec celle-ci, tout comme le moniteur série.
Je vous joins une photo des 2 cartes, ainsi que le code utilisé dans un second poste.
Code :
`[Code]/**
- "Object Placement" Puzzle
- This puzzle requires the player to place one or more items in the
- correct location, at which point an RFID tag embedded in the object
- is detected by a sensor.
- When all sensors read the tag of the correct object, the puzzle is solved.
- Demonstrates:
-
- SPI interface shared between several devices
-
- RFID library

Quelqu'un a t'il déjà eu le problème avec ce genre de carte ?
J'ai bien sur déjà changé les affichage Baud de 9600 à 115200 sur le scrip et le moniteur, mais rien n'y fait.
Merci d'avance pour votre aide.
