Linear actuator uses a lead screw driven by a permanent magnet dc motor to create linear motion from a dc voltage. When power is removed linear actuator will hold its position. However, if a force ...

“Building a Lower-power Linear Actuator with Arduino: quite a few people have asked me about scaling down openDog to make it lighter and cheaper, so I thought I’d discuss the options in this ...

You can make a pretty easy automatic feeder using a glue stick, cardboard, a continuous-rotation servo, and an Arduino to control the servo.
