This is a very popular LCD Keypad shield for Arduino and other variants. It includes a 2×16 LCD display and 6 momentary push buttons. Pins 4, 5, 6, 7, 8, 9 and 10 are used to interface with the LCD. Just one Analog Pin 0 is used to read the five pushbuttons. The LCD shield supports contrast adjustment and back-lit on/off functions. It also exposes five analog pins with color code for easy analog sensor plugging and display. The on board LED indicates power on.
This design is great since easily lets you keep connecting sensors to the rest of the pins, and use it for monitoring or menu selection with the push buttons even for gaming. Often project applications require testing or debugging. Displaying information right away help on most occasions when a computer is not at reach. If you are planning to build something not attached to a computer and you need to check what is going on when you place it on position, this addition will prove very valuable to make sure the program is running well.
