Your servo should be powered separately from the Arduino as it draws 150mA just running and its stall current is well over an amp, according to the specs on this page. If you're powering it from the Arduino, it is quite likely that it drags the Arduino's supply voltage down enough to shut down the processor, but you may be getting away with it for very short ...

I think you are totally misunderstanding, about variables and types and how using multiple servos with 1 function can work, and that this is your real question and not the thing with inserting variables (whatever you mean by that). You are trying to put together a string and use it as variable name. That does not work. A string is only a variable/instance ...

I had a project where I needed to run two steppers at the same time as they were moving a heavy load and were moving the same piece. While a servo is going to move the desired spot, a stepper will not. In the process of setting up the stepper you designated steps per rev and amount of steps to take at a time. The stepper is only going to move the "amount of ...
