Joystick Module

The Joystick Module project demonstrates how to interface a joystick with an Arduino Nano. The joystick consists of two potentiometers (for X and Y axis movement) and a button. This project reads the X and Y values, along with the button state, and prints them to the serial monitor.

Components Needed

• Arduino Nano
• Joystick Module
• Jumper Wires

Circuit Diagram

Circuit Setup

1.Connect Joystick Module to Arduino Nano:

Connect the VCC pin of the joystick module to the 5V pin on the Arduino Nano.

Connect the GND pin of the joystick module to the GND pin on the Arduino Nano.

Connect the VRx pin (X axis) of the joystick module to the A0 pin on the Arduino Nano.

Connect the VRy pin (Y axis) of the joystick module to the A1 pin on the Arduino Nano.

Connect the SW pin (Button) of the joystick module to the D2 pin on the Arduino Nano.

Instructions

1.Circuit Setup:

Wire the joystick module to the Arduino Nano as described in the circuit setup section.

2.Code Upload:

Connect the Arduino Nano to your computer via USB.

Open the Arduino IDE and paste the provided code.

Upload the code to the Arduino Nano.

3.Testing:

Once the code is uploaded, open the serial module.

Move the joystick and press the button. The X, Y values, and button state will be printed to the serial monitor.

Applications

Game Controllers: Use the joystick to build custom game controllers.

robotics: Control robot movement with the joystick module.

User Interfaces: Integrate the joystick into various interactive projects requiring directional input and button presses.

Notes

Ensure proper connections to avoid erroneous readings.

Use INPUT_PULLUP mode for the button pin to utilize the internal pull-up resistor, making it easier to detect button presses.
