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

It is same with the number of pins, order of pins and the purpose of pins. Adjust the potentiometer to solve this problem. Save me jud162a lot of time digging through spec sheets. LM35 is the temperature sensor used in this project.


So the knowledge on interfacing LCD module to arduino is very essential in designing embedded systems. The JHDA lcd module has 16 pins and can be operated in 4-bit mode or 8-bit mode. Here we are using the LCD module in 4-bit mode. Why these resistors like nd 10k are used? Program for scrolling the LCD screen using Arduino. The full program jhd612a interfacing LCD to arduino is shown below.

The circuit diagram of the LCD thermometer using arduino is shown in the figure below. RS jbd162a of the LCD module is connected to digital pin 12 of the arduino. The most basic form of electronic display available is 7 Segment display — which has its own limitations. Contrast adjustment; through a variable resistor.

Please learn the difference and in the future, give more thought to the title of your articles such that the title reflects what the article is actually about. Ajay — We shall! These two thing are VERY ,cd.

The arduino can be powered through the external power jack provided on the board. Output pin pin 2 of the LM35 is connected to A1 pin of the arduino. Enable jhd162 is used to switch between these 2 modes.


Refer the — documentation of LiquidCrystal Library — before you continue down! 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. Great tutorial with examples! For shorter texts more number of positions must be scrolled at a time to get a smooth display.

Anode of the back light LED.

Interfacing LCD to Arduino-Tutorial to Display on LCD Screen

This pin is used for selecting between read and write modes. Low to write to the register; High to read from the register. The 10K potentiometer is used for adjusting the contrast of the display. If you have any doubts or you come across any problems while interfacing, please ask in comments section.

The next best available option is Liquid Crystal Displays which comes in different size specifications. LCD modules form a very jjhd162a part in many arduino based embedded system designs. Vcc pin pin 1 of the LM35 is connected to A0 pin of the arduino.
