The jumper allows you to choose the power supply (Vin or Vdd) for the Parallax
Standard Servo. If you are using a 9 V battery, it is best to set it to Vdd. Either setting will
work if you are using a 6 V battery pack. Use only Vdd if you are using a DC supply that
plugs into an AC outlet. Before using a DC supply, make sure to check the specifications for
acceptable DC supplies listed in Appendix D: Batteries and Power Supplies.
Build the circuit shown in Figure 4-6.
Make sure you did not plug the servo in upside-down. The white, red and
black wires should line up as shown in the figure.
