Not sure if I have more of a programming question or Electronics question.
I would like to know how to control my servo such that it spins continuously in one direction; is that possible?
I have an analog servo.
It depends. If it's a "true" servo then no; if it's modified (or modifiable) to be a so-called "continuous" servo, then yes.
I guess what I really want is a motor to play around with something that resembles a Helicopter.
Thanks for the reply.
A continuous rotation servo could be used in a non-flying toy helicopter to make the rotors move slowly. A small DC motor would probably be more suitable. Dismantled servos can be a cheap source of small DC motors!
A flying helicopter needs a powerful high speed motor.
