Sorry this reply is in English, but the first adapter has the polarity reversed (inner pin is negative, should be positive) and this will not work with the Arduino. Most boards have a diode that will protect the board from damage due to reversed polarity but to be safe its best not to try connect it up.

et pourquoi ne pas utiliser l'USB en attendant de récupérer l'adaptateur ?
