Then open the serial monitor, you need to modify the displayed bit rate and the
bit rate set in the code to 115200, so that the display will not appear garbled. You can
observe the data changes corresponding to each button by rotating the buttons of A0,
A1, A2, A3, and A6. When the buttons of A0, A1, A2, and A3 are rotated, the data
change range is from 0 to 180. The data becomes smaller when rotating clockwise,
and the data becomes larger when rotating counterclockwise. When the A6 button is
rotated, the data change range is 35~90. When it is rotated clockwise, the data
becomes smaller, and when it is rotated counterclockwise, the data becomes larger.
