This is a very popular LCD Keypad shield for Arduino and other variants. It includes a 2x16 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 DFRobot color code for easy analog sensor plugging and display. The on board LED indicates power on.

This lcd arduino shield has 5 keys — select, up, right, down and left which allow you move through menus and make selections straight from one board attached to yourArduino project without requiring a massive tower of shields.

This design allows 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. 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.

The used LCD pins are not exposed on top side of the board leaving only the unused ones. This way, conflict with LCD pins on top of the board will not happen anymore. This design includes a APC / Bluetooth v3 socket to enable you data transmission with your robot.

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.  Good library support makes this easy to use as shown in the example program below.

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.

Many of the other pins not used by the LCD or buttons come out to break-out pads on the shield making them available.  Wires or headers can be soldered to these pads if desired.

The holes along the bottom edge of the board connect to all the pins from RST on the left thru A5 on the right but skips pin A0 which is used by the buttons.

The LCD uses a parallel bus and is somewhat complex to drive directly.  Fortunately the LiquidCrystal.h library comes standard with the Arduino IDE that makes it very easy to use the display.  There are other libraries available that have enhanced functionality as well.  It uses the 4-bit data bus mode to minimize the number of I/O used by the LCD display

The other buttons will report that the button was pushed and will also printout the ADC value that was read which told it which button had been pushed.

The LCD Keypad shield (DFRobot Compatible) is developed for Arduino compatible boards, to provide a user-friendly interface that allows users to go through the menu, make selections etc. It consists of a 1602 white character blue backlight LCD. The keypad consists of 5 keys — select, up, right, down and left. To save the digital IO pins, the keypad interface uses only one ADC channel. The key value is read through a 5 stage voltage divider.

This handy Arduino Uno shield comes equipped with a 1602A 16x2 LCD screen (with a trimpot for adjusting contrast) and 6 tactile momentary pushbuttons, and keeps the original pinout accessible!

This is a very popular LCD Keypad shield for Arduino or Freeduino board. 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. Analog Pin 0 is used to read the pushbuttons. The LCD shield supports contrast adjustment and backlit on/off functions. It also expands analog pins for easy analog sensor reading and display.

Raspberry Pi 1602 LCD module with keypad is a 16x2 LCD monitor with 5 buttons (Up / Down / Left / Right / OK to select), that can be inserted directly on the PI GPIO I2C interface expansion chips, and PI links only use I2C signal. Controlling this module using Python is simple and you can directly call the library functions. You can display two lines of 16 letters, which is suitable for some simple text messages. Five key buttons on LCD1602, provides an input interface which lets you build a desired menu interface on the display. RGB LED with different input level, can display seven kinds of colors. This is a plug and play device which can be inserted directly on the PI GPIO interface.
