LCD Shield with Keypad for the Arduino
LCD Shield with Keypad for the Arduino – Description
To begin with this is a very popular LCD Keypad shield for Arduino.
Therefore it can be directly plug onto the Arudino board, no soldering or fly-wiring needed.
It also got 6 buttons (keys) on the shield that can be used to navigate the LCD screen and to “select” actions from a menu on the screen.
The arduino LCD Keypad shield is developed for Arduino compatible boards.
To provide a user-friendly interface that allows users to go through the menu, start selections etc.
It consists of a 1602 white character blue back light LCD.
This keypad comprises 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.
The arduino LCD Keypad shield – INTRODUCTION
This is an extremely popular LCD Keypad shield for Arduino and other variants.
It includes a 2×16 LCD display and 6 momentary push buttons.
Pins 4, 5, 6, 7, 8, 9 and 10 are controlled to interface with the LCD.
Just one Analog Pin 0 is controlled 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 shows power on.
This lcd arduino shield has 5 keys — select, up, right, down and left which allow you move through menus.
And prepare selections straight from one board attached to your Arduino project without requiring a massive tower of shields.
This setup allows you to 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 helps 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 look at what is going on when you place it on position.
This addition will prove very valuable to make sure the program is running well.
It does not expose the used LCD pins 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 an APC/Bluetooth v3 socket to enable your data transmission with your robot.
They design the shield for ‘classic’ Arduino such as the Uno, Duemilanove, Diecimilla, etc.
