Crush Cans Effortlessly with an Arduino-Powered Arm

Use an Arduino and an H-bridge motor circuit to build an automatic can crusher. 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. You can easily control these 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! “
