The problem is, I'm a newbie in this stuff, and I find it very difficult to write something in Arduino. I can read (and understand) the code, but rewriting it is a bit difficult for me. I really thought it was easy to implement an example into a bluetooth signal, but unfortunately, that's not the case. Sadly, the examples that you gave were not giving me enough input to solve the problem. I think I should upload the servo instructions with USB to the Arduino, and after that, I can change the angle and the speed of the servo. However, I don't know how to do that... I'm really stuck, and I'm kinda frustrated..
