Arduino Brushless DC Speed AND Direction Control Setup (Part 1)

Speed and direction control of an 8A Brushless DC motor ($7) using an 18A ESC ($8) and a 10A Double Pole Double Throw [DPDT] relay ($10). Speed control is achieved by varying the duty cycle of a 50Hz digital pulse from the Arduino to the ESC signal wire. Direction control is achieved by wiring the ESC==Relay==Motor so that when the relay switches, it reverses two of the three phases to the motor.
