telecommande infrarouge

bonjour, je voudrais savoir pourquoi mon programme ne fonctionne pas, les erreurs qu'elles sont elles? car je pouvais rajouter à ma bibliothéque le irremote.h mais quand je le faisais cela me méttait des erreurs comme quoi des variables n'étaient pas définits. c'est pour cela que j'ai directement rajouté tous le programme et plus le programme que je devais écrire. donc maintenat les variablent sont bien définient mais les erreurs ont bien changées.
le programme etait celui la:
/*
   reception infrarouge
*/

#include <irremote.h>

int broche_reception = 11; // broche 11 utilisée
irrecv reception_ir(broche_reception); // crée une instance
decode_results decode_ir; // stockage données reçues

void setup()
{
  serial.begin(9600);
  reception_ir.enableirin(); // démarre la réception
}

void loop()
{
  if (reception_ir.decode(&decode_ir))
  {
    serial.println(decode_ir.value, hex);
    reception_ir.resume(); // reçoit le prochain code
  }
}
les erreurs sont:

sketch_may02a:8: error: 'irrecv' not name type
sketch_may02a:9: error: 'decode_results' not name type
sketch_may02a.ino: in function 'void setup()':
sketch_may02a:14: error: 'reception_ir' not declared in scope
sketch_may02a.ino: in function 'void loop()':
sketch_may02a:19: error: 'reception_ir' not declared in scope
sketch_may02a:19: error: 'decode_ir' not declared in scope


mais j'ai rajouté tous le irremote.h:
/*
   reception infrarouge
*/

ouais euh pourquoi recréer un topic ?
