Hello, Does anyone know how to use a hall effect sensor with the EZ-B? I had planned to use one to locate a position for a modified servo however I hooked it up to an ADC port but I don't get a reading. I do with my VOM for continuity but that is it. Any other solution for locating a position for a modified servo would be great also. Many thanks in advance and happy holidays!
Well got the chips today did a quick lash up and it works!
I need to play around with it some more but the principle is sound. Interestingly the way its wired at present I get a lower voltage on the ADC port when stalled moving forward and a higher voltage when stalled moving backwards helpful
Might add a say (Ouch) when Omnibot touches something great fun
Totally cool. I got to have one.

@winstn60,
That is great! Plus you just gave me an idea for LEGION, my RAD 2.0 robot. He has hands that open/close and right now I have no way of sensing when the hands close or open to much...the gears on the arms are designed to 'pop' when the arms close/open too wide but it sounds horrible and can't be good for the gears! I am thinking I might be able to use one of these sensors on the arm motors. Looks like the sparkfun board will be perfect! If that works, I may put one on the tracks to keep him from trying to climb the walls too! Thanks!
