DFRobot 1602 LCD Keypad Shield for Arduino

This LCD keypad shield from DFRobot plugs directly onto an Arduino UNO and is suitable for first experiments with driving a 1602 LCD display. The 5 buttons can be used to build a menu. All buttons are on analogue input A0, which saves digital inputs: each button produces a different voltage there. The unused pins are brought out on pin headers, so further sensors can be connected.
