COMPONENT :

Arduino UNO Board

Joystick Module

LEDs

Resistors

Jumper wires

Breadboard

THEORY :

The Joystick module provides Analog Outputs and the output voltages provided by this module keep changing according to the direction in which we move it. And we can get the direction of movement by interpreting these voltage changes using some micro-controller (we are using Arduino UNO).

CONNECTION :

The module has 5 pins: Vcc, Ground, X, Y and Key .

CODE :

int button=2; int buttonState0 = 0; int buttonState1 = 0;

void setup()

{   pinMode(7,OUTPUT);

pinMode(8,OUTPUT);

pinMode(9,OUTPUT);

pinMode(10,OUTPUT);

pinMode(11,OUTPUT);   pinMode(button,INPUT);   digitalWrite(button, HIGH);   Serial.begin(9600); }

void loop()

{  int x = analogRead(A0);  int y = analogRead(A1);

  Serial.print(x);   Serial.println(y);

  buttonState0 = digitalRead(button);   Serial.println(buttonState0);   if (x>=0 && y<=10)   {     digitalWrite(10, HIGH);   }   else

{

digitalWrite(10, LOW);

}

  if (x<=10 && y>=500)   {     digitalWrite(11, HIGH);   }   else

{

digitalWrite(11, LOW);

}

  if (x>=1020 && y>=500)   {     digitalWrite(9, HIGH);   }   else

{

digitalWrite(9, LOW);

}

  if (x>=500 && y>=1020)   {     digitalWrite(8, HIGH);   }   else

{

digitalWrite(8, LOW);

}

  if (x>=1020 && y>=1020)   {     digitalWrite(9, LOW);     digitalWrite(8, LOW);   }

  if (buttonState0 == LOW)   {     Serial.println("Switch = High");     digitalWrite(7, HIGH);   }   else

{

digitalWrite(7, LOW);

}   buttonState1 = digitalRead(button);   Serial.println(buttonState1);   delay(50); }
