One of the basic interfacing requirements for the hobbyists or electronics enthusiasts is I/P (keypad) and O/P (LCD display)  for proyotype applications. This shield uses minimum number I/O’s that is 2 bits(D0 and D1) for LCD data . 5 input key switches (Navigation keys), when it's activated serial data will be sent to pin  D0 by internal 2 line LCD controller. Each key has been pulled up to a different voltage level, so a different voltage will be generated every time a user selects a key. This voltage could be read by the analog pin of internal 2 line LCD controller on the board. Hence saves the no of I/O pins.  The backlight of the LCD could be controlled by setting PWM (Pin D10) by adding a few lines of code.

Pull-up resistors are used in electronic logic circuits to ensure that inputs to logic systems settle at expected logic levels, if external devices are disconnected or high-impedance is introduced. They may also be used at the interface between two different types of logic devices, possibly operating at different power supply voltages.A pull-up resistor weakly "pulls" the voltage of the wire it is connected to towards its voltage source level when the other components on the line are inactive.
