I guys, i´m trying to make an arduino based vending machine for my final year project, and i have 2 codes, but i can´t put them all in one. One code is for the Vending Machine and it uses an infrared sensor to detect the coin but i want to put an coin aceeptor so that it will be more realistic. The another is for the coin aceptor. Can you guys please give me advice? i´ve been trying to put them in the same code all afternoon
Vending machine code
#include <LiquidCrystal.h> // includes the LiquidCrystal Library
#include <Servo.h>
LiquidCrystal lcd(27, 26, 25, 24, 23, 22); // Creates an LC object. Parameters: (rs, enable, d4, d5, d6, d7)

int buttonPressed;

lcd.begin(16, 2); // Initializes the interface to the LCD screen, and specifies the dimensions (width and height) of the display
servo1.attach(4);
servo2.attach(5);

}
if(total_amount<10) display.showNumberDecEx(total_amount10, 0b10000000, true, 2, 2);
else
display.showNumberDecEx(total_amount10, 0b00100000, false, 4, 0);
}
Sorry if the information i give was not enough, but i really need help
