LCD (Liquid Crystal Display) screen is an electronic display module and find a wide range of applications. A 16×2 LCD display is very basic module and is very . The JHDA display controller is a monochrome LCD module which you can find bundled with various Arduino starter kits or on their own;. Silicon TechnoLabs LCD 16×2 Alphanumeric Display (JHDA) for , AVR, Arduino, PIC, ARM All (Yellow): : Industrial & Scientific.

Your email address will not be published. The LM35 temperature sensor is interfaced to the analog input pins of the arduino. Please help me for resolve the issue.

Thanks circuits today team to provide us better circuit guidence and project. It is a three terminal linear analog temperature sensor. A 16×2 LCD means it can jhd162w 16 characters per line and there are 2 such lines. You may also like: This library can handle both 4 bit mode and 8 bit mode wiring of LCD.

The most basic form of electronic display available is 7 Segment display — which has its own limitations. Backlight V CC 5V. Excellent breakdown and I jh1d62a sure many readers will agree this is one of the best we explanations on the LCD display we have read, so many thanks for taking so jh1d62a trouble to explain all so clearly.

Ajay — We shall! It is jgd162a with the number of pins, order of pins and the purpose of pins. So you will have to adjust the values of current limiting resistor to suit the brightness you desire. Interface Arduino to 7 Segment Display — learn how to interface 7 segment display to arduino with examples on interfacing 1 digit seven segment display common cathode and anode versions and 4 digit seven segment display common cathode and anode versions. Other Important aspects of Program.


Sends data to data pins when a high to low pulse is given. For shorter texts more number of positions must be scrolled at a time to get a lccd display.

16 x 2 LCD Datasheet | 16×2 Character LCD Module PINOUT

The JHDA jhd162x 16 pins and can be operated in 4-bit mode using only 4 data lines or 8-bit mode using all 8 data lines. These modules are preferred over seven segments and other multi segment LED s.

Supply voltage; 5V 4. The commands and data are fed to the LCD module though these pins.

RS pin of the LCD module is connected to digital pin 12 of the arduino. This declaration is what makes the program to understand the type of LCD module number of columns and lines of modules used in hardware. The JHDA has two registers namely command jhe162a and data register.

The arduino can be powered through the external power jack provided on the board. Program for scrolling the LCD screen using Arduino. The only difference is in the setup part of the arduino program, where we declare the number of columns and rows lines of LCD module.


Low to write to the register; High to read from jhr162a register. The 10K potentiometer is used for adjusting the contrast of the jyd162a.

This is just a practical implementation of the interfacing of LCD and Arduino.

Register for product notification

Purushotham — Thanks for the comment. The voltage at the VEE pin defines the contrast. Refer the — documentation of LiquidCrystal Library — before you continue down! If you have any doubts or you come across any problems while interfacing, please ask in comments section. Digital thermometer using arduino. Interface SD Cld with Arduino. We are working on more Arduino projects. Hi iam a beginner to your tutorial. Here we are using the LCD module in 4-bit mode.

When operated on 5V, a ohm resistor should be connected in series to this pin. I want to mount the display remote from Arduino as Jhd1162a need to use many inputs — will it drive say over 1 meter ok?

LCD modules form a very important part in many arduino based embedded system designs. The full program for interfacing LCD to arduino is shown below. Also make sure jhx162a have connected data lines properly to Arduino.
