I plan to build an off road traction control system roughly based on this link. http://blog.chryslerllc.com/blog.do;jsessionid=F83B4BCDB38454BD1A43D066882C5EAE?id=270&p=entry
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.
I have seen a lot of tutorials to build a window motor servo. http://www.fieroaddiction.com/servo.html
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?
