![]() ![]() Since we were only using one LED matrix and therefore one chain, we wired the components only according to the smiley face icons. Following the diagram under the “Wiring” section, we connected all of the corresponding pins. Since the diagram for the connections was laid out by physical pin number location and we didn’t need the PiTFT for this project, we removed the PiTFT (which we had used during the semester) from our Raspberry Pi 3 so we could directly connect the LED matrix and our Pi. On the github page for the library, we found a link to wiring instructions for the library. We quickly found this library that is compatible with all versions of the Raspberry Pi and downloaded it onto our Pi. Unfortunately, even after following the link, we didn't see any library suggestions for our microcontroller, so we went hunting for a library ourselves. On the Adafruit overview page for setting up the LED matrixes, the first paragraph is a warning stating that the guide only works for certain Adafruit micro controllers, none of which were the Raspberry Pi 3 that we were using.
