LCD1604

A four-line version of the standard character LCD, showing sixteen characters per line. The extra two lines matter more than they sound: a menu system, a set of sensor readings or a status display becomes genuinely usable when four values fit on screen at once instead of scrolling. Uses the same HD44780 controller and the same LiquidCrystal library as a 1602. Four lines display more data without scrolling; Same library and code as a 1602 display; Clear backlit text readable in any light; Well suited to menu systems and multi-sensor readouts
