i think you don't follow me.
The 6 objects are rotating. so light ans ultrasonic can't work.
is it possible to scan 6 different rf transmitters to measure their distance away from each other?
I am working on a project that requires for me to measure electronically the distance(cm) of a rotating object. The full range needed is 3 meters maximum.
I was looking into infrared and ultra sonic but this will be effected by objects getting in the way.
Does anyone have a good solution for me?
