Code Examples

### Example 1: Basic Joystick Reading with Arduino

This example demonstrates how to read the joystick's x-axis and y-axis values using an Arduino board.

```c++
const int xPin = A0;  // x-axis pin
const int yPin = A1;  // y-axis pin

void setup() {
  Serial.begin(9600);
}

void loop() {
  int xValue = analogRead(xPin);
  int yValue = analogRead(yPin);

Serial.print("X-axis: ");
  Serial.print(xValue);
  Serial.print(" | Y-axis: ");
  Serial.println(yValue);

delay(50);
}
```

### Example 2: Joystick-Controlled Robot with Raspberry Pi

This example shows how to use the joystick module to control a robot's movement using a Raspberry Pi.

```python
import RPi.GPIO as GPIO
import time

GPIO.setmode(GPIO.BCM)

# Joystick pin connections
xPin = 17
yPin = 23
zPin = 24

GPIO.setup(xPin, GPIO.IN)
GPIO.setup(yPin, GPIO.IN)
GPIO.setup(zPin, GPIO.IN, pull_up_down=GPIO.PUD_UP)

while True:
    xValue = GPIO.input(xPin)
    yValue = GPIO.input(yPin)

if xValue > 500:
        print("Moving right")
    elif xValue < 200:
        print("Moving left")
    else:
        print("Stationary")

if yValue > 500:
        print("Moving forward")
    elif yValue < 200:
        print("Moving backward")
    else:
        print("Stationary")

time.sleep(0.1)
```

### Example 3: Joystick-Operated LED Matrix with ESP32

This example demonstrates how to use the joystick module to control an LED matrix using an ESP32 board.

```c++
#include <WiFi.h>
#include <Adafruit_GFX.h>
#include <Adafruit_LEDBackpack.h>

Adafruit_8x8matrix matrix = Adafruit_8x8matrix();

const int xPin = 32;  // x-axis pin
const int yPin = 33;  // y-axis pin

void setup() {
  Serial.begin(115200);
  matrix.begin(0x70);  // Initialize LED matrix
}

void loop() {
  int xValue = analogRead(xPin);
  int yValue = analogRead(yPin);

if (xValue > 500) {
    matrix.fillScreen(LED_RED);
    matrix.writeDisplay();
  } else if (xValue < 200) {
    matrix.fillScreen(LED_GREEN);
    matrix.writeDisplay();
  } else {
    matrix.fillScreen(LED_OFF);
    matrix.writeDisplay();
  }

if (yValue > 500) {
    matrix.setTextWrap(false);
    matrix.setTextColor(LEDYELLOW);
    matrix.setCursor(0, 0);
    matrix.print("UP");
    matrix.writeDisplay();
  } else if (yValue < 200) {
    matrix.setTextWrap(false);
    matrix.setTextColor(LEDYELLOW);
    matrix.setCursor(0, 0);
    matrix.print("DOWN");
    matrix.writeDisplay();
  } else {
    matrix.fillScreen(LED_OFF);
    matrix.writeDisplay();
  }

delay(50);
}
```

These examples demonstrate the versatility of the Joystick Module and its potential applications in various IoT projects.
