I'm new to this whole servo controller animation. Do the servos operate in both directions from one channel? I've gotten an r3 uno board but I'm not clear on the control of the servos. For 4 servos do you only need 4 channels?

Servo position is controlled with pulse length, so to answer your question, yes, one channel per servo. Typical servo position is from 900us to 2100us.
