Connecting pushbutton with Arduino and making light patterns

It's so cool if we press a button and all the LEDs dance on our command. So let's get started!

Connection of Push button with Arduino and LEDs

This connection is for example. You have to do connection as commented in the code. This code is to show you only the connection! Do It Yourself!

Code

Upload this code and see results by simply pressing the pushbutton

C/C++
I highly recommend to type this code (in short) so you can get familiar with all the commands that are used in this code!
int L1 = 3; // connect LED1 to digital pin 3
int L2 = 4; // connect LED2 to digital pin 4
int L3 = 5; // connect LED3 to digital pin 5
int L4 = 6; // connect LED4 to digital pin 6
int L5 = 7; // connect LED5 to digital pin 7
int L6 = 8; // connect LED6 to digital pin 8
int L7 = 9; // connect LED7 to digital pin 9
int L8 = 10; // connect LED8 to digital pin 10

int buttonState = 0; // Assign a button value
int buttonPin = 2; // connect Push Button to digital pin 2

int de = 50; // it's delay which is used later in patterns of LEDs

int p = 0; // It's the pattern number of LEDs

void setup() {
  pinMode(L1, OUTPUT);
  pinMode(L2, OUTPUT);
  pinMode(L3, OUTPUT);
  pinMode(L4, OUTPUT);
  pinMode(L5, OUTPUT); // Declare all LED pins as OUTPUT pins
  pinMode(L6, OUTPUT);
  pinMode(L7, OUTPUT);
  pinMode(L8, OUTPUT);

  pinMode(buttonPin, INPUT); // Declare Push Button Pin as INPUT pins
}

void loop() {
  buttonState = digitalRead(buttonPin); // Connect Push Button to Arduino
  
  if (buttonState==HIGH)

  {
    p++;              // This 'IF' condition specifies that whenever Push Button is pressed, that will do increment in pattern numbers
    delay(500);
