Hey, I have 2 separate codes for my capping machine that i need to combine into 1 for my Arduino Mega. The first code is for a LCD display to count the cap's in the holister and the second one is for the machine that tightens the caps.
I want 2 combine the 2 codes into 1 for my Arduino Mega...
What is the best way to combine the 2?
Or is there someone that can put them together for me?
Thank you in advance! 
CODE 1 (Display Cap Counter)
//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;

} else {
// if the current state is LOW then the button went from on to off:

// Delay a little bit to avoid bouncing

// save the current state as the last state, for next time through the loop
