It will start out with some information, and then we will build circuits on a breadboard. My approach is to be very basic, acting as a summary of the learning I did to be able to complete the hardware. the built-in Pi functionality.īecause this garage door project really is a multi-part process comprising Pi hardware, software, and installation with your garage door opener(s) I thought I would first focus on the Pi hardware, since it is needed for every other step. I also learned about the benefits of pull-up and pull-down hardware circuits vs. Not being a seasoned electronics person, I did a whole lot of additional research on ways to interface with the Raspberry Pi and learned a lot about the importance of resistors with LED bulbs and with all GPIO wiring. One of the inspirations for this project was the fine instructable at Raspberry Pi 3 Garage Door Opener, along with several others found on the Internet.
