LCD 20X4 (2004) Yellow Serial Backlight with IIC

2004 LCD display module is a 4 line 20 character LCD module not only set the contrast control knob selector switch also has a backlight and IIC communication interface. For Arduino beginners, not for the cumbersome and complex LCD driver circuit connection and a headache, the real significance of this LCD module will simplify the circuit, this module directly into the Arduino Sensor Shield V5.0 sensor expansion board, GM 4P sensor connection cable, programmed through the Arduino controller, you can easily identify the slogan, sensor data records. 

Features：
IIC/I2C interface was developed to reduce the IO port usage on Arduino board.
