Project 1 - Interfacing a 16*2 LCD with Arduino using I2C protocol

OFFLINE:

#include
void setup()
{
 pinMode(A0,INPUT);
  Wire.begin();
}
void loop()
{
  int x=analogRead(A0);
  float value=((x*5)/1024);
  int temp=((value-0.5)*100);
   Wire.beginTransmission(8);
  Wire.write(temp);
  Wire.endTransmission();
  delay(1000); // Wait for 1000 millisecond(s)
 
}

#include
#include
LiquidCrystal lcd(12,11,4,5,3,2);
void setup()
{
 Serial.begin(9600);
  Wire.begin(8);
 lcd.begin(16,2);
   Wire.onReceive(display);
}
void loop()
{
  delay(1000); // Wait for 1000 millisecond(s)
}
void display(int x)
{
 int y=Wire.read();
  Serial.print(y);
 
  lcd.setCursor(0,0);
  lcd.print("the voltage");
  lcd.print(y);
  lcd.clear();
  delay(1000);
