Custom CE Indicator Project

I have a few CE elevator indicators laying around and I wanted to get them up and working. However, these displays use a custom communication system that requires one of their controllers to use. I recently acquired one of these controllers and I decided to build a circuit to run the displays! The display drivers come in different types, and mine takes a binary input. I programmed an arduino to send inputs into the display driver to make a little elevator simulator. I also set up a remote control system which allows the user to enter a floor for the elevator to go to! See the video to see how I built the controller and what it does!
