A servo can drain a fresh 9 V battery in less than 20 minutes. For tips on using a separate
power supply for a servo on the HomeWork Board, see the Parallax servos product pages (linked

Important!
Use a separate AA-size battery pack to power the servo. Connect as shown, being
sure not to mix up any of the wires. You can use alkaline or nickel metal hydride (NiMH) cells.
