Building a weather dashboard with an LCD
Now that we have our weather data, it's time to wire our character LCD to our Pi and use it to show the weather data. We'll explore the Johnny-Five LCD object, wire it to the Pi, and code it all together with Johnny-Five and the npm request module.
Adding an LCD to the Pi
Refer to the following diagram for the connection:
Note
Keep in mind that backpack with the I2C interface is on the back of the LCD; I moved it forward in the diagram to help you see the connections to the Pi.
The LCD object
Let's take a look at the LCD object in the Johnny-Five documentation in order to figure out how to construct and use our LCD in our weather dashboard code.
Constructing our LCD
Usually, an LCD without the I2C can take up to eight pins! That's a lot, and I like as few wires as possible in my robotics projects (easier to debug later). With our backpack, we only need the two power pins and two I2C pins. But that also means we'll need to find our controller—if you are using...
