In this project, we have looked at an add-on piece of hardware for the Raspberry Pi and the Scroll pHAT HD; we also saw how we can adapt this to work in our projects. You also learned about sources of information about how we need to wire these add-ons to our Raspberry Pi computers if we are not using the standard hat method; this will come in useful in future projects too!
We then looked at how we can control the Scroll pHAT HD add-on board with some simple Python code. There is plenty of scope here for personalizing this project here, and we now know where to find the online documentation to learn what else this board can do.
Another important step covered was to make Python programs we write start automatically when we power up our Pi Zero. We did this twice just in this project, and this is something we will need to do for most of the remaining projects in the book...
