Re: Hall Effect Sensor.

We got it up and running last night, very cool. A couple of things... We did not use pin 3 (internal connection), I bet it is a safeguard for grounding and we may hook this up and retry it soon. As far as mounting it, we made a small hole in the top of the transmission closest to the 50 tooth output gear and wired it to a piece of proto circuit board and connected it directly to the analog input on the RC via PWM cable. The sensor must get fairly close to the gear teeth, within a 2-4 mm. Also its "self adjusting" which means you can't move it once your program is running. You have to adjust it then reset the program. Also run a test program in user_routines_fast.c . I'll take a picture of our simple test setup tomorrow and post it here.
