1602 lcd module v3 display with keypad price

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

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:

They are both used for screen printing and as a result of the standard functions. 1602 LCD displays only enable wholesale touch options to be easily displayed.

1602 LCD display are larger and have a larger frame than 1602 lcd display. They are differed from the other types of lcd displays, as they enable different functions and have different functions.

Pin 3: VL is the contrast adjustment terminal of the LCD. The contrast is the weakest when connected to the power supply. The contrast is the highest when grounded. When the contrast is too high, it will produce ghost images. When using it, the contrast can be adjusted by a 10K potentiometer.

Pin 5: R / W is the read-write signal line, read operation when high level, write operation when low level. When RS and R / W are both low level, you can write instruction or display address, when RS is low level, R / W is high level, you can read busy signal, when RS is high level, R / W is low level Data can be written.

LCD1602 Character LCD expansion board, PCB technology processing, enough material, mainboard adopt brand new high-quality 2 lines 16 characters LCD, contrast control, backlight select switch, and 4 direction keys, 1 select button, 1 reset button; It simplify the circuit in a real sense, directly insert the plate to Arduino controller.
