Review on 📺 SunFounder IIC I2C TWI 1602 Serial LCD Module Display for Arduino R3 Mega 2560 16x2 - Enhanced Arduino Display for Projects by Dave Neal

I bought a SunFounder IIC I2C TWI Serial 2004 20x4 LCD Module Shield for Arduino Uno Mega2560 in early 2017. The I2C interface promised a much cleaner interface than the standard interface. at a loss to find drivers and sample code to drive it. I finally found this code that initializes the board. It works with version 1.1.2 of Frank de Brabander's LiquidCrystal_I2C library included in version 1.8.2 of the Arduino IDE#include <Wire.h>#include <LiquidCrystal_I2C.h>LiquidCrystal_I2C lcd(0x27,20,4 ); invalid settings() { wire.begin(); lcd.init(); lcd.backlight();} Using the code I already had I was able to get them to work with the new board.
