1602 LCD Board Keypad Shield
The 1602 LCD Keypad Shield is an affordable and easy way to add a simple 16 x 2 LCD screen and 5 button menu to your Arduino projects. The LCD Display uses the LiquidCrystal library that comes standard with the Arduino IDE. The library examples work with the following change in the initialization: LiquidCrystal lcd(8, 9, 4, 5, 6, 7. The 5 navigation buttons use a resistor ladder to connect to analog pin 0. Just use the analogRead(); command to read in the different values.
