LCD Shield with Keypad

The LCD Keypad shield is developed for Arduino compatible boards. It provides an easy and user-friendly interface with both LCD and keypad 5 buttons.

It consists of a character blue backlight LCD and of 5 keys – select, up, right, down and left. To save the digital IO pins, the keypad interface uses only one ADC channel. The key value is read through a 5 stage voltage divider.
