Lcd shield for arduino? how to use it?

Other Hardware LEDs and Multiplexing

i want to make a project about a color sensor using ldr and LED 4 pins and i have the schematic but this project use a servo
like this :Reva123 Santosa | Flickr
i want to modify the project with lcd shield for arduino so i don't use servo for it, and i use this: https://www.flickr.com/photos/79136967@N04/14071800495/when it detects red color it will be "red" on the display (lcd) and i don't use the keyheads. i dont know how to use lcd shiled for arduino because it is even my first time using arduino and i don't know the coding as well #include <LiquidCrsytal.h> or any else? please help me i beg you =( =(
and this is the coding if it use the servo:
#include <Servo.h>
Servo myservo;
int sensorPin = A0;
int LedBiru =3; // Led warna biru digital pin 3
int LedHijau=4; // Led warna hijau digital pin 4
int LedMerah=5; // Led warna merah digital pin 5
int hasil,hasilb,hasilm,hasilh;
int k=8; // toleransi warna

void setup() {
// declare the ledPin as an OUTPUT:
pinMode(LedBiru,OUTPUT);
pinMode(LedMerah,OUTPUT);
pinMode(LedHijau,OUTPUT);
digitalWrite(LedBiru,LOW);
digitalWrite(LedMerah,LOW);
digitalWrite(LedHijau,LOW);
myservo.attach(9); // motor servo pin digital 9
myservo.write(90);
delay(100);
Serial.begin(9600);
delay(1000);
}

void loop() {
// nyalakan LedMerah
digitalWrite(LedMerah,HIGH);
//delay 150 ms agar LDR baca stabil
delay(150);
// baca data sensor
hasil= analogRead(sensorPin);
hasilm=map(hasil,0,1023,0,255);
Serial.print("R,G,B = ");
Serial.print(hasilm);
digitalWrite(LedMerah,LOW);
delay(150);

// nyalakan LedHijau
digitalWrite(LedHijau,HIGH);
//delay 150 ms agar LDR baca stabil
delay(150);
// baca data sensor
hasil= analogRead(sensorPin);
hasilh=map(hasil,0,1023,0,255);
Serial.print(",");
Serial.print(hasilh);
digitalWrite(LedHijau,LOW);
delay(150);

// nyalakan LedBiru
digitalWrite(LedBiru,HIGH);
//delay 150 ms agar LDR baca stabil
delay(150);
// baca data sensor
hasil= analogRead(sensorPin);
hasilb=map(hasil,0,1023,0,255);
Serial.print(",");
Serial.println(hasilb);
digitalWrite(LedBiru,LOW);
delay(150);

// cek warna dibandingkan dengan nilai hasil kalibrasi
if(abs(hasilm-208)<k && abs(hasilh-203)<k && abs(hasilb-177)<k){
Serial.println(" -> WARNA PUTIH!\n");
myservo.write(10); } else
if(abs(hasilm-209)<k && abs(hasilh-165)<k && abs(hasilb-139)<k){
Serial.println(" -> WARNA MERAH !\n");
myservo.write(30); } else
if(abs(hasilm-135)<k && abs(hasilh-182)<k && abs(hasilb-147)<k){
Serial.println(" -> WARNA HIJAU !\n");
myservo.write(50); } else
if(abs(hasilm-138)<k && abs(hasilh-163)<k && abs(hasilb-166)<k){
Serial.println(" -> WARNA BIRU !\n");
myservo.write(70); } else
if(abs(hasilm-156)<k && abs(hasilh-184)<k && abs(hasilb-172)<k){
Serial.println(" -> WARNA CYAN !\n");
myservo.write(90); } else
if(abs(hasilm-199)<k && abs(hasilh-159)<k && abs(hasilb-170)<k){
Serial.println(" -> WARNA UNGU !\n");
myservo.write(110); } else
if(abs(hasilm-209)<k && abs(hasilh-214)<k && abs(hasilb-223)<k){
Serial.println(" -> WARNA KUNING !\n");
myservo.write(130); } else
if(abs(hasilm-210)<k && abs(hasilh-206)<k && abs(hasilb-211)<k){

myservo.write(150); } else
if(abs(hasilm-165)<k && abs(hasilh-197)<k && abs(hasilb-205)<k){
Serial.println(" -> WARNA HIJAU MUDA !\n");
myservo.write(170); } else
// if(abs(hasilm-209)<k && abs(hasilh-204)<k && abs(hasilb-210)<k){
// Serial.println(" -> WARNA KUNING MUDA!\n");
// myservo.write(180); } else
Serial.println(" -> ???\n");

delay (2000);
}
please help me i don't know what to do ... i beg you

Look at this --> section 7 about using code tags. Then stop begging for help. It is undignified.

Does the code work with your current setup? Does the Serial.print output give the correct (or close enough) result?

Removing the Servo code is trivial - unless I misunderstood the question - just delete those code lines that use it.

So all you want to do is to replace Serial.print with LCD.print ? ... have you looked at the example sketch File->Examples-LiquidCrystal->HelloWorld ?

We all were "newbies" at some point in time. (I noticed your earlier post) If this project is "too much", then try someting simpler first. As you learn by experimenting you will find how to do this.
