Bonjour, je suis vraiment tout nouveau et cherche à faire fonctionner une arduino mega pour faire un genre de batterie électronique. (12 capteurs piezo sur les entrées analogiques pour déclancher 12 notes midi)
J'ai trouvé ce code, mais il y a une erreur (Arduino : 1.8.5 (Mac OS X), Carte : "Arduino/Genuino Mega or Mega 2560, ATmega2560 (Mega 2560)"
TEST_03_XYLOPHONE_FOR_TABLE:11: error: too many initializers for 'char [6]'
'A0','A1','A2','A3','A4','A5','A6','A7','A8','A9','A10','A11'};
^
exit status 1
too many initializers for 'char [6]'
S'il y avait une âme charitable qui voulait se pencher sur mon problème ... ! Par avance merci !!! 
J'utilise 12 capteurs piezos sur les entrées analogique servant à "déclancher" 12 notes midi. les piezos ont une résistance de 1MΩ en parallèle.
voici le code complet:
