LCD Shield

A 16x2 character display and a five-button keypad on one shield that plugs directly onto an Uno with no wiring at all. That combination gives a project a complete user interface — display, navigation and select — in a single part. The buttons are read cleverly through one analogue pin using a resistor ladder, so all five cost you just A0. The standard choice for menu-driven instruments and standalone devices. Complete display and keypad interface, zero wiring; Five buttons read on a single analogue pin; Backlight controllable from software; Ideal for menu-driven standalone instruments
