I have an application where I want to use an aftermarket car door lock solenoid as a cheap linear actuator (because it’s basically what it is). It will run off 9-12V and be outside. It needs to be activated with an RF remote switch.
So these are two wire devices. Power it with a certain polarity and it extends. Reverse the polarity and it contracts.
What I need it to do specifically is to extend fully when activated by the RF switch, then hold for a set time 10-15secs by stopping power to the solenoid, then reverse polarity and fully retract, then switch off again. I’d prefer to just use off-the-shelf stuff rather than go down the path of coding a Wemos D1 or a NodeMCU but will if I have to. Coding is not my strong point.
