Arduino Counter with LCD display and Push button Tutorial

Schematic diagram

Arduino Sketch
//YWROBOT
//Compatible with the Arduino IDE 1.0
//Library version:1.1
#include <Wire.h>
#include <LiquidCrystal_I2C.h>

LiquidCrystal_I2C lcd(0x3F,16,2); // set the LCD address to 0x27 for a 16 chars and 2 line display

// this constant won't change:
const int Up_buttonPin = 2; // the pin that the pushbutton is attached to
const int Down_buttonPin = 3;

// Variables will change:
int buttonPushCounter = 0; // counter for the number of button presses
int up_buttonState = 0; // current state of the up button
int up_lastButtonState = 0; // previous state of the up button

int down_buttonState = 0; // current state of the up button
int down_lastButtonState = 0; // previous state of the up button
bool bPress = false;

void setup()
{
Serial.begin(9600);
pinMode( Up_buttonPin , INPUT_PULLUP);
pinMode( Down_buttonPin , INPUT_PULLUP);

lcd.init(); // initialize the lcd

// Print a message…

How to connect an I2C LCD Display to an Arduino MEGA 2560

Schematic diagram

1. Connect the Black jumper cable from the GND pin on the LCD to the GND pin on the MEGA 2. Connect the Red jumper cable from then VCC pin on the LCD to the 5V pin on the MEGA 3. Connect the Green jumper cable from the SDA pin on the LCD to the SDA pin on the MEGA 4. Connect the Yellow jumper cable from the SCL pin on the LCD to the SCL pin on the MEGA
