Servo's and EduBots?

[DanL]

I'd like to mount a servo onto the edubot for testing purposes, but alas, I don't much about servos.

This thread did a nice job explaining servos, but I still want to make sure of a few things.

About the actual connection, as I understand it, servo's don't need to be hooked up to the victors because the pwm outputs on the RC provide the necessary signal and voltage to power them. All you have to do is in the code put in the appropriate number for the pwm output, hook the servo directly to that output, and voila! serv-tastic (I think?)

Now, as for hooking a servo (not the modified edu-servos, but one of the servo's from the full robot kit) up to the EduBot controller, page 7 on the EduBot manual describes the PWM output ports. However, there are still a few things I'm shakey about servo-wise. Mainly, does a servo have two or three wires? I haven't examined them closely yet. If three wires, what are they? Also, where can I find the specs on the servos? Checking the robot documentation, the only thing they said about the servo was it was from Innovation First, but I didn't see them on the IFI documentation.

Anyways, what I'm trying to say is this: I'm going to hook a servo from the kit up to the edu controller, just I'm not sure how to go about doing it. I'm guessing a servo has two leads, and you hook it up to the rightmost and third-from-right pins on the edu pwm output (page 7, edu controller manual). What I'd like to know is if everything I've said here is right, or am I on the path to burn out our servos and possibly more?
