Blue Display I2C 16X2 LCD Module

This LCD display is compatible with Arduino and uses I2C to provide 2 lines of 16 characters. It displays white characters on a blue background and has a backlight which can be enabled or disabled. It's easy to display alphanumeric data using the Arduino LCD library.

Only two Arduino ports are used (usually A4 and A5 but it depends on exact Arduino model, see online Arduino documentation for more details).
