I wanted to repurpose my raspberry pi to be a garage door opener. I tried several different methods to make this work, but wasn’t happy with how it was coming out, so I came up with more-or-less my own easy custom solution that I wanted to share.
Of course, you have to start by setting up Raspian on the Pi.
Then, enable VNC, SSH, and the camera in the settings.
VNC makes it a heck of a lot easier to log in once you've put the pi in the garage.
There were three things I needed to add to my Pi:
A camera
A relay switch
and a reed switch
Next, there are 4 pieces of software to install:
1. Apache (will allow you to create a web page to control the pi from a phone)

2. Webcam (so you can look and see what state the garage door is in, as a visual check)

3.Node.js (allows for the algorithms to be written in javascript, my language of choice)
