This Arduino Linear Actuator Tutorial shows how to control a Firgelli Small Linear Actuator using an arduino compatible board and a RobotGeek Joystick for incremental movement.
For Arduino Linear Actuator projects the small linear actuators by Firgelli are excellent. These linear actuators have an internal controller which allows them to be operated just like a servo. By using the Arduino Servo Library we can simply send out the desired position to the actuator and it moves to the position.
For this tutorial we are reading in from the joystick and incrementally moving the goal position in or out and then sending the new goal position to the actuator. When the joystick is let go and snaps back to center the goal position sits idle leaving the small linear actuator in place.
