If you're just getting into Arduino, you may not be aware that you can't just connect a big motor to the pins of the board and start moving it. You have to use some switching mechanism to carry the high current load. You can use a motor driver or H-bridge, but the simplest, fastest way is to use a couple relays or a relay board. You have two options when using an Arduino with a linear actuator.
Firgelli Automations is one of the original linear actuator and TV Lift manufacturers. Since 2004 we have been developing our own line of Linear Actuators, Track actuators, TV Lifts, Desk Lifts, and many other Motion control products to support many different industries.
Our products have been used in just about every application you can imagine from home automation to space exploration. Firgelli Group is on the leading edge of Linear Actuator research and development, searching for innovative solutions to linear motion control.
