Hello, for a school project (a device like a guitar that has strings on it, and from a data read from internet some motors pulling the strings to play sounds) I am looking for some servo or stepper motors to use with Arduino. I did not decided yet to what kind of motor to use but I am really looking for some help.
Anyone have some experiences with those motors please can point me to a webpage/article/etc.. about Arduino and motors ?
Or any article about how to control 6 to 8 Servos with arduino ?
I read on forum that only 2 Servos can be controlled with the Servo library. So do I need to get 4 Arduinos to control 8 Servos ?
And for a project like that which will go best ?
I have (by luck) some Dynamixel AX-12's in hand but they can not be used with Arduino as far as I see on the forums.
Be aware of the differences between a "servo" a "servo motor" and a "stepper motor". It's confusing, and unclear, but a "servo" as mention on these forums is nearly always a radio-controlled model component comprising a DC motor, gearing, feedback pot and error amplifier, all inside a plastic box. It's driven by a pulse, which is normally supplied by a radio-control receiver, but which we generate with an Arduino (of course). Some sources use the term "servo motor" to mean a DC motor that it designed to be used in a motion-control system, as opposed to a motor used purely as a source of mechanical power. Finally, a "stepper motor" is a type of motor that moves in discrete steps and not continuous rotation (although of course you can make it step quite fast and appear continuous).
