Arduino LCD1602 Keypad Shield Best price in Egypt

SOLD OUT Arduino LCD1602 Keypad Shield

This is a 16x2 LCD and Keypad shield for Arduino Uno, Diecimila, Duemilanove and Freeduino boards.

  • Blue Backlight with white words
  • uses 4 Bit Arduino LCD Library
  • Left, Right, Up, Down and Select buttons
  • Screen contrast adjustment
  • Arduino Reset button

The board uses different pins to the Arduino example sketches, so to make the display work, use the following sequence of pins when starting the library:

LiquidCrystal lcd(8,9,4,5,6,7);

The buttons are connected to only one analog input pin through resistors to give a different voltage for each button, thus saving on input/output pins. Reading the buttons is easy and example code is shown below

Pin Connections

PinFunction
Analog 0Buttons (select, up, right, down and left)
Digital 4DB4
Digital 5DB5
Digital 6DB6
Digital 7DB7
Digital 8RS (Data or Signal Display Selection)
Digital 9Enable
  

Note: Do not use pin Digital 10 when this board is plugged in (see here for more details)

The board is a little bigger than an Arduino UNO (measuring 8cm x 6cm). This can be seen in the images.

// include the library code:
#include <LiquidCrystal.h>

// initialize the library with the numbers of the interface pins
LiquidCrystal lcd(8, 9, 4, 5, 6, 7);

void setup() {
  // set up the LCD's number of columns and rows:
  lcd.begin(16, 2);
  // Print a message to the LCD.
  lcd.setCursor(0,0);
  lcd.print("LCD Key Shield");
  lcd.setCursor(0,1);
  lcd.print("Press Key:");
}

void loop() {
  int x;
  x = analogRead (0);
  lcd.setCursor(10,1);
  if (x < 60) {
    lcd.print ("Right ");
  }
  else if (x < 200) {
    lcd.print ("Up    ");
  }
  else if (x < 400){
    lcd.print ("Down  ");
  }
  else if (x < 600){
    lcd.print ("Left  ");
  }
  else if (x < 800){
    lcd.print ("Select");
  }
}
