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 4 bits for LCD data and 2 control signal lines for the same. A single analog pin (Pin A0) is multiplexed to read 5 input key switches (Navigation keys). 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 A0 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.

Power line communication refers to the concept of the transmitting information using the main

power line as communication channel. The Greatest benefit of the power line communication systems is that they use existing power lines as communication medium instead of using costly wireless equipment or dedicated communication wiring and hardware. This provides a strong motivation to use an existing power lines for communication purposes in addition to their use for power distribution thereby, taking advantage of already existing electrical network that is present in almost any building, whether industrial,commercial or residential.
