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.

The board has only one SSR driven by TTL circuit . The board works on 12V but the input signal can come directly from microcontroller output working at 5V to control SSR. Each SSR can switch varierty of AC or DC high voltage, high current loads working at 110V or 220V AC mains like lights, fans, motors and such. The status of SSR is indicated by LED.
