Sample Code

#include <Wire.h>  //invoking I2Clibraries coming with Arduino
#include <LiquidCrystal_I2C.h>
LiquidCrystal_I2C lcd(0x27,16,2); 

int temp;

// the setup routine runs once when you press reset:
void setup() {
  // initialize serial communication at 9600 bits per second:
  lcd.init();
    delay(100);
    lcd.backlight();
    Wire.begin();  //initializing I2C
    lcd.clear(); //clear screen

    delay(100);
    lcd.setCursor(2,0);
    lcd.print("ACS712 TEST");
    delay(200);
  Serial.begin(9600);
}
// the loop routine runs over and over again forever:
void loop() {
  // read the input on analog pin 0:
  float current = analogRead(A0);
  temp=current;
  temp=temp-512;
  current=temp/35.8;
  //lcd.clear(); //clear screen
  // print out the value you read:
  Serial.print("current=");
  Serial.print(current);
  Serial.println("A");
  lcd.setCursor(0,1);
    lcd.print("Current=");
    lcd.setCursor(8,1);
    lcd.print(current);
    lcd.setCursor(15,1);
    lcd.print("A");
  delay(300);        // delay in between reads for stability
}
