Story

This is a project that uses a generic joystick and using the Arduino reads the +y and -y values and the +x and -x values and using a series of if and else statements will tell the 5 leds which led to turn on for ex: If you rock the joystick to the left your left led will light up. Another feature is that if your joystick has a button (most will) it will light up your button for your press down feature.

Code

The code

#define joyX A0
#define joyY A1

int button=2;
int buttonState = 0;
int buttonState1 = 0;

void setup() {
  pinMode(7,OUTPUT);
  pinMode(button,INPUT);
  digitalWrite(button, HIGH);
  Serial.begin(9600);

  pinMode(8,OUTPUT);
  pinMode(9,OUTPUT);
  pinMode(10,OUTPUT);
  pinMode(11,OUTPUT);
}
 
void loop() {

 int xValue = analogRead(joyX);
 int yValue = analogRead(joyY);
  Serial.print(xValue);
  Serial.print("\t");
  Serial.println(yValue);
  
  buttonState = digitalRead(button);
  Serial.println(buttonState);
  if (xValue>=0 && yValue<=10)
  {
    digitalWrite(10, HIGH);
  }
  else{digitalWrite(10, LOW);}

  if (xValue<=10 && yValue>=500)
  {
    digitalWrite(11, HIGH);
  }
  else{digitalWrite(11, LOW);}

  if (xValue>=1020 && yValue>=500)
  {
    digitalWrite(9, HIGH);
  }
  else{digitalWrite(9, LOW);}

  if (xValue>=500 && yValue>=1020)
  {
