I have kind of a small round board atop my bot, spinning driven by a DC motor. When the encoder shows that it has turned the exact required amount, I want to keep it steady unable to turn anymore until next order. External forces exist that could make it to rotate in one sense or the other.
Can this (breaking ?) be achieved with a common DC motor or should I resort to a modified RC servo? Whatever helps in saving power, much better.
No previous experience. That's why such a basic question. :?:
