KY-023 Joystick Module

/*
This code reads the position of the joystick and the state of the button on the KY-023 Joystick Module and prints the result on the Serial Monitor of the Arduino IDE. The analogRead() function is used to read the X-axis and Y-axis analog values from the joystick, and the digitalRead() function is used to read the button state. The map() function is used to convert the analog values to joystick positions within the range of -100 to 100.

To use this code, connect the X-axis and Y-axis outputs of the KY-023 Joystick Module to the analog input pins of your Arduino board (usually A0 and A1 for most Arduino boards), and connect the button output of the joystick to a digital input pin of the Arduino board (in this case, pin 2). The joystick should be powered with a 5V DC power source.

Note that the joystick positions and button state may vary depending on the type and quality of the joystick module used.
