Arduino Linear Actuator Tutorial - Analog Direct Control of Small Linear Actuator

Direct Control

This Arduino Linear Actuator Tutorial shows how to control a Firgelli linear actuator using an Arduino and stationary analog sensors. For this tutorial we use a slider and rotation knob for direct control of the linear actuators mapping absolute position from the sensors to the actuator position.

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.
