You can use them with LCD modules that have a HD44780 compatible interface with various screen sizes by attaching to the back of the LCD module. Now a days, it is not necessary to buy an expensive I2C LCD for this task because readymade serial backpack modules for standard LCDs are available at reasonable rates. However, if you use an LCD module with I2C interface, you only need 2 lines to process the display information. To link a standard 16×2 LCD directly with the microcontroller, for instance Arduino, you would need atleast 6 I/O pins to talk to the LCD. Assume that you are moving towards a complex microcontroller project bundled with blinkers, beepers, and a display panel.
