16×2 LCD Keypad Shield Arduino LCD Keypad 1602 LCD Keypad Shield With Blue Backlight For Arduino Blue Screen Backlight Versatile LCD Keypad For Electronics Projects

Description:

The LCD1602 16×2 Blue LCD with Keypad Shield provides a 16 character x 2 line LCD and keypad in an Arduino shield format for providing a user interface for a project. This shield incorporates a 16 character x 2 line blue LCD display.  It uses a 4-bit parallel bus to communicate with the MCU. The backlight has a multi-turn potentiometer for adjusting the contrast of the display for best viewing.

16×2 LCD Keypad Shield module includes a small keypad that has UP/DOWN/LEFT/RIGHT/SELECT buttons. The last button is a remote RESET button. The buttons (except for reset) all connect to a resistor voltage divider that come into the analog input A0.  The output of the voltage divider will vary depending on which button is pushed, so reading the value on analog pin A0 allows you to determine which button was pushed.  The example program below shows how this is done in the Read_Buttons() function.
