Ok, I am a bit new to this so I'll ask you guys to take it a bit easy on the first timer. My goal is to build a circuit that measures the distance from point A to point B. Point A being the end of an arm that is suspended over the ground and point B being the ground itself. Total distance between the two points could range from 6 inches to 6 feet. Anyway, as the arm travels over uneven ground, the distance between the arm and the ground changes and I would like to eliminate those changes by maintaining a set distance. So as I travel across the ground, I want to capture that (distance) data whether it be measured in voltage, frequency... and compare it against a set value and change the height of the arm over the ground accordingly so that the arm always maintains a specific distance above the ground. What I am lacking is a way to measure the distance. Any devices or ideas out there that anyone would recommend?
Thanks,
Dave
