/*
Example code for 1.28 inch, 240*240 TFT LCD Display which uses the GC9A01 driver.  The code rotates a needle
around a pivot point (think compass needle).  Thanks to "Volos Projects" on YouTube.
Original code ref: https://github.com/VolosR/RotateSpritesTutorial/blob/main/RotateSpritesTutorial.ino

I adapted the example code for my LCD that is 240x240 and used some variables in the process
