[Noisebridge-discuss] High torque servos?

[Gopiballava Flaherty]

Wait, what? Did I miss a schematic or something?

Servo control pins are low current signal pins. You hook the power pins to you bower supply and the control pin to an IO pin. The servo itself has the transistors and stuff needed so you can avoid an H bridge. 

Thanks,
