Hello! My name is Eugene So. I am a Master’s student at New Jersey Institute of Technology (NJIT) majoring in Electrical Engineering. This website describes how to build your own linear actuator or motor using a pair of solenoid valves and an Arduino microcontroller. The linear actuator I am describing was built at NJIT in 1994 by a Master’s student named Alex Rokhvarg under the direction of Dr. Bernard Friedland. My Master’s project was to retrofit the controller for this apparatus. I used the Adafruit Metro M4 as the new controller. Here is a video demonstrating the linear actuator.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
