Program KickStarts
Each of the example programs turn the servo counter clockwise, then clockwise, and finally
stops. This movement is repeated indefinitely.
Important! Servo motors draw only minimal current when they’re not attached to a mechanical
load, such as the leg of a robot. The example connection diagrams shown here provide only
modest current to the servo, so they are not intended to move heavy loads. They’re useful for
demonstration only. To operate bigger loads the servo motor should be connected to its own 4.8
V to 6 V battery supply. See the links below for information on how to use separate power to
operate one or more R/C servo motors.
Due to slight differences in electronic circuitry within the CR Servo, you may need to adjust the
servo mechanics so that the motor stops moving when pulses of exactly 1500 μs are supplied.
An externally-accessible trimmer control on the side of the CR Servo allows you to calibrate the
stop point. Slowly adjust the control using a small (#0 or #1) Phillips screwdriver while applying
a stream of 1500 μs pulses to the servo, 20 ms apart. Calibration programs are provided in this
KickStart.
