Common or uncommon sensors used in FRC

From what I heard, this can be accomplished easier by plugging the limit switch directly into a Jaguar, and using jumpers to determine which directions the motor can rotate when the switch is activated. You will have to consult the Jaguar information sheet for this, though, as I have never attempted this.

I implemented one of those in 2011 for a soft stop on our robot's elevator--it wasn't too bad, although if I remember correctly I had to solder a few transistors onto a proto board and stick it between the switch and the Jag jumper to step down the voltage.

Also, our team tried out a Hall Effect(magnetic) sensor this year to work was a soft stop for the cam that pushed our Frisbees into our shooter, and it worked perfectly--all the convenience and functionality of a limit switch, but with no physical contact involved, so it never wore out!
