به منظور اتصال lcd كاراكتري معمولي به بورد آردوينو به 6 پين ديجيتال نياز داريم ، در صورتي كه با استفاده از رابط I2C ، تنها با استفاده از 2 پين ديجيتال ميتوانيم lcd را راه اندازي كنيم. توسط پتانسيومتر روي برد ميتوان كنتراست lcd را تنظيم كرد.

Serial I2C LCD display adapter converts parallel based 16 x 2 character LCD display into a serial i2C LCD that can be controlled through just 2 wires. Adapter uses PCF8574 chip that serves as I/O expander that communicates with Arduino or any other microcontroller by using I2C protocol. A total of 8 LCD displays can be connected to the same two wire I2C bus with each board having a different address. The default i2C address is 0X27 and may be changed to any of the following 0X20~0X27 via soldering A0 A1 A2 pins.
