The LCD Keypad shield is developed for Arduino compatible boards, to provide a user-friendly interface that allows users to go through the menu, make selections etc.
It consists of a 1602 white character blue backlight LCD.
The keypad consists of 5 keys — select, up, right, down and left.
To save the digital IO pins, the keypad interface only uses one ADC channel.
The key value is read out through a 5 stage voltage divider.
