It has 8 keys which can be connected to any microcontroller or any interfacing kit directly. KEY is a small key pad designed to data entries for microcontroller board.The board has 10-pin header for 10-wire ribbon cable. By default the switch status would be pulled up, every time you press a key the corresponding switch header changes its state to the common header in the board.

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.
