Joystick

The Joystick project demonstrates how to use a joystick module with an Arduino Mega to read the X and Y axis positions and the button state. The project prints the joystick's position and button state to the Serial Monitor and lights up an LED when the button is pressed.

Instructions

Circuit Setup:

Connect the Joystick module and LED to the Arduino Mega as described in the circuit setup section.

Code Upload:

Open Arduino IDE and create a new sketch.

Copy and paste the provided Arduino code into the sketch.

Testing:

Upload the code to the Arduino Mega.

Open the serial monitor in Arduino IDE (set to 9600 baud).

Move the joystick and observe the X and Y values printed to the Serial Monitor.

Press the joystick button and observe the button state and LED behavior.

Notes

Adjust the delay in the

Ensure the joystick is centered for accurate readings. You may need to calibrate the joystick based on your specific module.

The internal pull-up resistor is used for the button pin to keep it in a known state when not pressed.
