control analog signal using xbee and arduino uno

Using Arduino Project Guidance
#1

i need to read any analog sensor like variable resistance and show it in another board on lcd
i try to control digital signal and i success in this code

Receiver

int LEDredPin =12;			
int LEDgreenPin = 13; 			
void setup() {				

  Serial.begin(9600);			
 pinMode(LEDredPin, OUTPUT);		
 pinMode(LEDgreenPin, OUTPUT);	

}

void loop() {			
  if (Serial.available()) {	//If there is data in the Serial Line
    int dataByte = Serial.read(); 


          if(dataByte == 'H'){		
              digitalWrite(LEDredPin, HIGH);	
              digitalWrite(LEDgreenPin, LOW);  

            }

          if(dataByte == 'L') {	
            
            digitalWrite(LEDgreenPin, HIGH);	
            digitalWrite(LEDredPin, LOW);		
                          }
                  }
            }

Transmitter

const int sw1=2;
const int sw2=3;
void setup()
{
  pinMode(2,INPUT);
  pinMode(3,INPUT);
  Serial.begin(9600);
}

void loop()
{
  if(digitalRead(sw1)==1)
{
  Serial.print('H');
}
  if(digitalRead(sw2)==1)
{
Serial.print('L');
}
}

but when i try to make analog signal i failed like this code

transmitter

void setup()
{
  Serial.begin(9600);
}

void loop()
{
  Serial.println(analogRead(A0));
}

Receiver

#include <LiquidCrystal.h>
LiquidCrystal lcd(7,8,9,10,11,12);
void setup() 
{				
  Serial.begin(9600);			
  lcd.begin(16, 2);
}

void loop() {			
  if (Serial.available()) {	//If there is data in the Serial Line
   int dataByte = Serial.read(); 
       lcd.setCursor(0, 1);
       lcd.print(dataByte);


          
            }
}
