Hello,
I have a project I'm working on and need a starter idea to get things going.
I was planing to build essentially a window motor servo, except I do
not need the infinite degrees of movement.
I plan on having this servo arm turn left, right or back to center. It
needs to be water proof, so my thoughts was, if I could get away from
having a pot sense degrees of movement, then I could easily make the
motor water proof. I did see motors like this where two positions were
involved. There was a switch to sense one position and a switch to
sense the other. I thought this made it simple to locate the position
of the motor turning.
FYI, I did some browsing and could not find related topics; I fear being the lazy guy who did not search.
My truck has wheel sensors on each rear wheel to monitor speed. I will have an arduino monitor the wheel speed of each wheel, and when the percentage of change reaches a certain tolerance, the arduino will intervene the faster spinning wheel by applying brake force to the e-brake cable.
The servo will apply the needed force to operate the brake cable.
The servo I need for the project needs to be waterproof. My thoughts were, if I used the pot to monitor degrees of motion, then the water proofing portion of this task would be much more difficult.
And, I only need the servo to be in a center position, 90 degrees left, or 90 degrees right. I had an idea of using magnetic switches, similar to home alarm systems. The switches are sealed, and assumably waterproof.
If I had a switch for each position of the servo arm(3, left, right, and center), would I be able to make this work with an arduino?
