Review on SunFounder I2C LCD Module Shield for Arduino R3 Mega2560 - 2004 20x4 Serial TWI by Noe Epps

Earlier in 2017 I bought a SunFounder IIC I2C TWI Serial 2004 20x4 LCD Module Shield for Arduino Uno Mega2560. The I2C interface promised a much cleaner interface than the standard interface. For a long time I could not find a driver and code example to control 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.
