this it's my first project, and a good starting point for the pursuing animatronics, which i am very much interested in for video.
all you really need to know is that i am trying to:
-make a motor rotate between a range of low speeds, clockwise and anti-clockwise based on the signal from a potentiometer, or some other controller.
this is to control the zoom ring on my camcorder's lens.
it needs to:
-be as quiet as possible (for obvious recording reasons).
-have a variety of speeds.
-ease in and out of zoom smoothly/seamlessly.
-have a control which is operably by my thumb alone, a left/right thumb-stick or a seasaw peddle would be ideal.
i am new to all this so please bare with me, i am trying my hardest but would greatly appreciate any advice/guidance/direction.
please help me, let me know what your approach would be.
