Activity 4: Connect Servo Motors and Batteries
From the robot navigation standpoint, continuous rotation servos offer a great combination
of simplicity, usefulness and low price. The Parallax continuous rotation servos are the
motors that will make the BOE Shield-Bot’s wheels turn, under Arduino control.
In this activity, you will connect your servos to the Board of Education Shield’s servo ports,
which will connect them to supply voltage, ground, and a signal pin. You will also connect a
battery supply to your Arduino because, under certain conditions, servos can end up
demanding more current than a USB supply is designed to deliver.
Servo Control Horn, 4-point Star vs. Round
It doesn’t make a difference. So long as it is labeled “continuous rotation” it’s the servo for your
BOE Shield-Bot. You’ll remove the control horn and replace it with a wheel.
