Linear servo motor arduino code#
This code will get us through the next three sections.
You can find this Demonstration Code in the RobotGeek Libraries and Tools under: RobotGeekSketches -> Demos -> LinearActuator -> linearActuatorExpDemo -> linearActuatorExpDemo.ino If you have multiple linear actuators, you can control up to 4 simultaneously with this code. Notice that you'll have to physically plug the linear actuator into different ports in order to move it with the different controls.
