You have a very common problem that is documented all over. You have two libraries, Servo and IRremote, that are both trying to use the same hardware timer. Do a little Google searching for possible fixes. You will need to either find a different Servo library or a different IRremote library.

  • Ty for the fast response i will try something before getting into any foward details. – Cristiano Santos Jun 6 '18 at 17:14
  • I have solved my problem. I changed the IRremote timer and it works just fine. – Cristiano Santos Jun 22 '18 at 14:27
