SunFounder ESP32 Starter Kit

The SW (Z-axis) pin is connected to IO33, which has a built-in 4.7K pull-up resistor. Therefore, when the SW button

is not pressed, it will output a high level. When the button is pressed, it will output a low level.

I34 and I35 will change their values as you manipulate the joystick. The range of values is from 0 to 4095.
