1x raspberry pi, with operating OS and wifi
1x hot glue gun
1x OLED
4x female to femal jumper wires
1x garage door left open notifier setup to point to the raspberry pi
1x raspberry pi oled case Stl here.
Print out the case pieces.
Insert the oled into the case, use hot glue to hold it. Wires go along the top of the lid.
Place the raspberry pi on the bottom. I didn't care if it moved around in there, so I didn't glue it in, but you can if you want it.
Connect the wires for the oled to the raspberry pi, according to the diagram.
Put the lid on the bottom piece, they should just snap together.
Plug in power for the raspberry pi and let it start up.
One the Raspberry pi, install nodejs and git if needed: sudo apt install nodejs git
Checkout the repo: git checkout https://github.com/thinklearndo/garagedooropennotifier
Install dependencies: cd garagedooropennotifier/nodejs && npm install
Start the nodejs server: nodejs app.js
Open a web browser on another computer and go to this URL: http://<ip address of raspberry pi>/garageAlert?doorState=1&doorId=0. The OLED should show the open garage door image.
Then to test that it will show the closed image, go to this URL http://<ip address of raspberry pi>/garageAlert?doorState=0&doorId=0.
