I'm looking to make a "button pusher" using a linear actuator and a relay. I am planning to connect this "button pusher" to a smart plug. I want it to extend when the smart plug is turned on and remain extended when the smart plug is turned off. Once the smart plug is turned on again, I want it to retract.I understand I need a mini linear actuator and a relay to reverse the polarity in order for the actuator to retract. Is there a way to do this without the use of an Arduino, Pi or physical switch?Perhaps using one of these actuators?Something like this but with a mini actuator and no remote control. via /r/DIY http://ift.tt/2xTeZ3H
