Title: Distance and direction sensor
Post by: Eithman1 on April 05, 2013, 07:24:04 AM
I was wondering if you guys know of any sensors that I could hook up to one arduino that could tell another one which direction it was and how far away it was. Any suggestion would be really appreciated!

This turns out the be a pretty hard problem. My first guess would be to use some kind of IR beacon on one, and sensor on the other, and put a tube in front of the sensor so it only senses a particular direction, and then put that whole sensor assembly on a servo that you can swivel around. That will give you direction. Add an ultrasonic sensor, perhaps, to get approximate distance? Assuming the remote Arduino is big enough to give a ultrasonic response.
