The board has only one  relay driven by TTL circuit and MCT2E IC for isolation purpose.The board works on 12V but the input signal can come directly from microcontroller output working at 5V to control relays. Relay can switch varierty of AC or DC high voltage, high current 20A,loads working at 110V or 230V AC mains like lights, fans, motors and such. The status of relay is indicated by individual LEDs.

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.

A 4x4 matrix keypad requiring eight Input/Output ports for interfacing isused as an example. Rows are connected to Peripheral Input/Output (PIO) pins configured as output. Columns are connected to PIO pins configured as input with interrupts. In this configuration, four pull-up resistors must be added in order to apply a high level on the corresponding input pins.

Note: The color of the PCB may vary. However the circuit/pinout of the PCB will remain same.

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.
