1602 lcd module v3 display with keypad in stock

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.

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 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

1602 LCD module read and write operations, the screen and cursor operations are programmed through the instructions to achieve. (Note: 1 is high, 0 is low)

This LCD Display Shield gives you a nicely mounted 1602 LCD Display snaps right on top of your Arduino UNO. With onboard buttons for easy navigation including up, down, left, right, select and reset, using your Arduino away from a computer was never easier. Use this shield to display values read in by your Arduino, display options for user inputs, choose between different programs you can run on your Arduino, etc. With a Power LED onboard and a nice blue backlit display, you"ll be able to use your Arduino"s LCD Display Shield day or night!

This shield is compatible with the "LiquidCrystal" library that is bundled with the Arduino software. Just edit the "LiquidCrystal" library"s default mapping from the LCD pins to Arduino pins to the ones for this specific shield by copying what"s shown below. Here is an example of the proper way to instantiate the LiquidCrystal class for this shield:

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.
