A good skill to have when building your own Johnny-Five projects is finding code and wiring diagrams for the components that you'd like to use. Luckily, the www.johnny-five.io website and the project provide a thorough and top-notch documentation right there on the site!
Let's take a look at the LCD documentation on the site to prepare us for building our project:
In the header of the site, click on the API tab.
Then, you'll see a list of components on the left (if you're on a desktop) or at the top (if you're on a tablet or phone).
Find and click the LCD entry in this list.
The API documentation page
Once you are on the LCD page, you'll see a bunch of different LCD components, a section on the LCD API, and some links to examples at the bottom. There is a page like this for every component in Johnny-Five, so it's easy to find out how to get started with just about every component that has already been adapted.
