I'm looking for some good ideas.
I have installed a garage door open on my observatory and it's working really well with the original wireless remote control.
As a next step, I want to control it from a computer. Inside the opener, it has 3 contacts - a ground, one to open and another one to close. I've tested it with a small piece of wire, and it works fine.
So how to trigger this from a PC? I was thinking of using a
Super4
Or perhaps an
Arduino Uno and a
relay shield.
Any other cost effective ideas? I don't mind if it's USB, Serial or Ethernet.
