By itself, an Arduino is incapable of driving servos, without a lot of hard work and pin munging. So we’re using a shield instead! This shield allows control of sixteen servos.
There are a total of sixteen servo connectors, grouped into four groups of four. Servo cables are connected with 0V (the black or brown wire) towards the side of the reset button.
The Arduino itself is powered entirely over USB. If you wish to use servos, you’ll need to supply an additional 5V through the connector on the shield from the power board. There are two red LEDs next to the power input that will turn on if the board is correctly powered.
