. The 16x2 is very common type LCD, with two rows, and each row displays 16 characters of either 5x7 or 5x8 dot matrix characters.
The LCD is available in a 16 pin package. It consists of back light and contrast adjustment function and each dot matrix has 5×8 dot resolution. The 16x2 LCD display is connected to the Arduino (A0,A1,A2,A3,A4,A5) analog IO pins, where those pins are configured as digital in / out, where LCD operates at 4 bit data mode. If the display is not visible, adjust the Contrast pot (1K), to make it visible. Matrix key pad is arranged by push button switches in rows and columns. In a simple technique, the 16 keys of matrix keypad is connected with 8 digital IOpins of Arduino.
Usually the keypad scan procedure is. The key is decoded through Column selection / Row read.

Write HIGH to Column One. And keep rest of the Column to LOW. Scan (Read) the Row One to Row Four, to find the key. Repeat until a key press (are multiple) is identified.
The Row pins are connected to 5,4,3 and 2nd digital IO pins of Arduino. The Column pins are connected to 6,7,8 and 9th digital IO pins of Arduino.
I built this, but the sketch does not compile, there were multiple faults This report would have more information with 'Show verbose output during compilation' enabled in File Preferences.
Contents. Introduction This is a very popular or Freeduino board.
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. Analog Pin 0 is used to read the push buttons. The LCD shield supports contrast adjustment and backlit on/off functions.
It also expands analog pins for easy analog sensor reading and display. The LCD Keypad shield is developed for, 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.
Specification. Operating Voltage:5V. 5 Push buttons to supply a custom menu control panel. RST button for resetting arduino program. Integrate a potentiometer for adjusting the backlight. Expanded available I/O pins. Expanded Analog Pinout with standard DFRobot configuration for fast sensor extension.
Dimension: 80 x 58 mm Pinout. Library Explanation Function Explanation LiquidCrystal(rs, enable, d4, d5, d6, d7) Creates a variable of type LiquidCrystal. The display can be controlled using 4 or 8 data lines. If the former, omit the pin numbers for d0 to d3 and leave those lines unconnected. The RW pin can be tied to ground instead of connected to a pin on the Arduino; if so, omit it from this function's parameters. For example: LiquidCrystal lcd(8, 9, 4, 5, 6, 7); lcd.begin(cols, rows) Initializes the interface to the LCD screen, and specifies the dimensions (width and height) of the display. Begin needs to be called before any other LCD library commands.for example: lcd.begin(16, 2); lcd.setCursor(col,row) Set the location at which subsequent text written to the LCD will be displayed.
For example: lcd.setCursor(0,0); lcd.print(data) Prints text to the LCD.for example: lcd.print('hello, world!' ); lcd.write(data) Write a character to the LCD. More function can see:. Tutorial Example 1 This example will test the LCD panel and the buttons.When you push the button on the shield,the screen will show the corresponding one. Connection: Plug the LCD Keypad to the UNO(or other controllers).
