Product Description

The IIC 2004 LCD display module is a 4 line 20 character LCD module with a manual contrast control knob, backlight and i2c communication interface.

The library that works with this display can be installed directly in the Arduino IDE Library Manager: LiquidCrystal I2C by Frank de Brabander.

Using the "HelloWorld" example sketch change the definition of the LCD to: LiquidCrystal_I2C lcd(0x27,20,4); 

We find some batches that use this direction: LiquidCrystal_I2C lcd(0x3f,20,4);


If you have troubles with the I2C directions, please use the i2c_scanner to find the correct one in case that the factory change it again http://playground.arduino.cc/Main/I2cScanner
