Once you have the TFT working, you can now continue onto a full test sketch, which will show how to read the light sensor, accelerometer, capacitive touch, and even the battery voltage! We do this all thru the Arcada library, which allows us to abstract a wide range of boards, from the PyBadge, to the Hallowing, so you don't have to worry about pin numbers or exact display parts.

Whew, once all are installed. You can load up the example code, which is in the Arcada Library -> Full Board Tests -> hallowingm0_arcadatest

Make sure once you've loaded it in, you have both the full_test code and the additional audio.h code

Upload and try it out! If you need to quickly test a board, here's the UF2 you can load on
