Code

The code that powers this project.

C/C++
It's a very simple coding, you can learn for it since I explained everything that's happening.
#include <LiquidCrystal.h> //include the LiquidCrystal.h library

LiquidCrystal lcd(7, 8, 9, 10, 11, 12); //declare which digital pins are controlled by the variable "lcd"

void setup() {
lcd.begin(16, 2); //declare the size of the LCD display (16x2)

lcd.print("10,");
delay(1000);
lcd.print("9,");
delay(1000);
lcd.print("8,");
delay(1000);
lcd.print("7,");
delay(1000);
lcd.print("6,");
lcd.setCursor(0, 1);
delay(1000);
lcd.print("5,");
delay(1000);
lcd.print("4,");
delay(1000);
lcd.print("3,");
delay(1000);
lcd.print("2,");
delay(1000);
lcd.print("1,");
delay(1000); 
lcd.clear();
lcd.setCursor(0, 0);
lcd.print("HAPPY NEW YEAR!! ");
}
void loop() {
}
