Driving servo motors is a simple operation. The 3 servos are operated at the same time, and in the same direction, so the voltage supplies, the grounds and the signals from the PIC are lumped together. The servos are powered with 5V at high current, #A, which is their maximum draw for maximum mechanical power. The signal wire for the 3 servos is connected to the signal hub to receive PWM from the PIC. A ground reference from the PIC is connected to the ground for the servos \cite{Electronics-Blog.comblog:2008}. The servo driver circuit can be seen in figure #. (!!!!!!!)
