This next program sets the Arlo’s motors to 20/127 of full power in the forward direction. If your Arlo goes forward while running this program, it indicates that your motors are connected correctly and the battery is charged.
IMPORTANT: Your Arlo will not be ready for the next step until it goes forward for this test.
