Building an affordable lower power linear actuator using little Arduino hardware and programming. James Bruton takes you through the process ...

Arduino is a good option when it comes to actuator control. With Arduino, you can apply linear actuators in multiple projects, even those that require top precision speed and movement accuracy.

Everything is controlled by an Arduino Mega. A beefy linear actuator works the brake and is attached temporarily with a band of Shapelock that slips around the pedal.

A linear actuator, of course! Although this could be done with other household implements, the form factor of this glue stick seems perfectly suited to sit on top of a servo horn.
