Linear actuators convert the fast rotation of a DC motor into slow linear movement, and they can provide quite a strong pushing or pulling force. The most basic definition of a linear actuator is that it’s a mechanical device that converts energy to create motion in a straight line; contrasted with circular motion of a conventional electric motor. It can also be used to apply a force.
You can easily control linear actuators using a simple H-bridge circuit — put it together with an Arduino and a bit of woodwork, and you can make yourself an automatic crusher for beverage cans — no soldering required!
Each Monday is ArduinoMonday here at Adafruit! Be sure to check out our posts, tutorials and new Arduino related products. Adafruit manufactures the Arduino right here in the United States in cooperation with arduino.cc. We have a huge selection of Arduino accessories and all the code and tutorials to get you up and running in no time!
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
