Arduino_Analog_Joystick_Library

A simple Library for a Arduino 2-axis analog joystick with select button. You can use multiple joysticks at once, given you create a separate object for each one.

Release Notes

Version 1.0

• added more directions to check (upper-left, upper-right, lower-left, lower-right and center)
• calibration checks individual limits of the x- and y-axis in order to calculate the gap
• if calibrated readX() and readY() account for it
• added getStats() to print initial x- and y-values and if calibrated the calibration-data

Version 0.9

• Initial Upload with incomplete functionality

Requirements

1x Arduino Uno R3
1x 2-Axis Analog Joystick with Switch-Button(KY-023 or similar) 6x Jumper Wire

Usage

// create joystick object with specified pin-layout
Joystick joystick(HORIZONTAL_PIN, VERTICAL_PIN, SELECT_PIN);
  
void setup() {  
    // dont touch your joystick here, since it is required to be in its resting position
    joystick.initialize();  
}  
  
...  
  
void loop() {  
    // left  
    if(joystick.isLeft())  
    {  
      Serial.println("Joystick is left");  
      Serial.println(joystick.readX());  
    }  
}
