Schematics

Gamepad Schematics or how to connect wires to arduino

This is the circuit to connect wires to Arduino and breadboard so u have a gamepad ready

Code

Arduino code

Arduino
This is code for Arduino u have to play on Arduino ide
const int UpButton = 9;//9 and 11 pins both only work as per circuit rest are not working as per circuit
const int DownButton = 11;
const int LeftButton = 10;
const int RightButton = 8;
void setup(){
   Serial.begin(9600);
   pinMode(UpButton, INPUT);
   pinMode(DownButton, INPUT);
   pinMode(LeftButton, INPUT);
   pinMode(RightButton, INPUT);
} 
void loop(){
    if(digitalRead(UpButton) == HIGH){
  //for(int i; i < 10; i++){ (this code is for to click button once but run the player 10 times ps: delete this line only not for int etc u understand)
    Serial.println("Up:");
    delay(1);
    }
   //}
    if(digitalRead(DownButton) == HIGH){
    //for(int i; i < 10; i++){
    Serial.println("Down:");
    delay(1);
    //break;
    }
   //}
    if(digitalRead(LeftButton) == HIGH){
    //for(int i; i < 10; i++){ 
    Serial.println("Left:");
    delay(1);
    //break;
    }
   //}
    if(digitalRead(RightButton) == HIGH){
    //for(int i; i < 10; i++){
    Serial.println("Right:");
    delay(1);
    //break;
    }
   //}
