How to edit this IR sensor code to COINSLOT sensor

Question

The project is Like a secured PiggyBank but it will count the coins inside it. Im using a coin sensor at default it has 5v, then goes to zer if inserted with a coin. I have 2 codes The one was form my old project then second one was a coinslot code got in youtube.

Im hoping someone can guide me where to deelte some codes, then add it at one lsit of code. Behavior of the project -Start > Display Total : Amount > if I will unlock the solenoid it will display Welcome "NAME" . Hope you can get my Idea. Some of code inside of the solenoid was not perfect sorry for that I just get it from scrath without proper knowledge.

This is code for FINGERPRINT TO SOLENOID LOCK

  lcd.setCursor(2,1);
  lcd.print(Names[finger.fingerID-1]); //Then print the name we gave it and the -1 is to remove the shift as the ID starts from "1" but the array from "0"
  return finger.fingerID;
}
/The two following functions depends on your locking system
 mine has a DC motor that should turn in both ways for opening and closing
 that's why I'm using H bridge, you could have a solenoid with a transistor
 then you'll need only opening sequence but controlling the transistor
 as the closing is spring loaded...

This code is for COINSLOT

#include <Wire.h>
#include <LCD.h>
#include <LiquidCrystal_I2C.h>
#include <EEPROM.h>
#define coinSlot 6
LiquidCrystal_I2C lcd(0x27,2,1,0,4,5,6,7); // 0x27 is the I2C bus address for an unmodified module
int coinCount = 0;
int coinSlotSignal;
int requiredCoins = 1;
boolean coinInserted = false;
void setup() {
  Serial.begin(9600); 
 pinMode(coinSlot, INPUT_PULLUP);
lcd.setBacklightPin(3,POSITIVE);
 lcd.setBacklight(LOW); // You can turn the backlight off by setting it to LOW instead of HIGH
 lcd.begin(16, 2);
lcd.write(EEPROM.read(5));
}
void loop() {
  while(!coinInserted){
  coinSlotSignal = digitalRead(coinSlot);
  if(coinSlotSignal < 1) {
    coinCount += 1;
    coinInserted = true;
EEPROM.write(0,coinCount);
Serial.println(EEPROM.read(0));
lcd.setCursor(0,0);
lcd.print("TOTAL:");
lcd.setCursor(0,1);
lcd.print(coinCount);
}
  }
while(coinInserted) {
  coinSlotSignal = digitalRead(coinSlot);
  if(coinSlotSignal >0) {
    coinInserted = false;
}
}
if(coinCount >= requiredCoins) {
  delay(1500);
}
}
