The table that shows the pin connection between Arduino Uno and 16×2 LCD without a potentiometer 16×2 LCD Arduino codeĪfter we finish 16×2 LCD interfacing with Arduino the most important thing is the code, this code will show you in the display “Hello world!” and the second-row “ROBOSANS”.

16×2 LCD interfacing with Arduino Uno without a potentiometerįollow this table down below which and just remove the potentiometer and connect the VEE pin to pin 13 and the GND. So the pictures downs below show the difference in connection in the detail. The connection with a potentiometer is the same as a without potentiometer but there is a little bit of difference. 16×2 LCD interfacing with Arduino Uno without a potentiometer

The table that shows the pin connection between Arduino Uno and 16×2 LCD with potentiometerĪnd the potentiometer is connected to the +5V and GND in addition to the output to the VEE pin. 16×2 LCD interfacing with Arduino Uno with potentiometerįollow this table down below which explains the connection between Arduino Uno and 16×2 LCD. Equipment Requirement:ġ6×2 LCD interfacing with Arduino Uno with potentiometerĪfter you knew the equipment requirement we needed to connect it together so the picture downs below show the connection in detail. You can interface 16×2 LCD with any Arduino type you want but in this tutorial, we will use Uno Arduino.īy using Arduino Uno you can display characters on the 16×2 LCD but there is some equipment to complete this experiment. You can interface 16×2 LCD with any Arduino type you want but in this tutorial, we will use Uno Arduino.

I have put the 16×2 LCD datasheet down below so you can download it.īut beware you may have a different datasheet, so also look at your datasheet or even the labels on your screen before the connection.

D0-D7 (Data Bus): this pin carries the 8-bit data and sends it to the display as a character in (ASCII code) so if set these pins as 0000 0001 you will see number 1 on the display.

E (Enable): this pin works as permission to the internal registers so it will help transfer the instruction from the data pins and another command to the 16×2 LCD.

RW (Read/Write): this pin decides if will read or write from the 16×2 LCD.

RS (Register Select): this pin helps to toggle between command/data register and it is known as a register select pin.

VEE (LCD Contrast): to control the 16×2 LCD contrast and brightness by using a potentiometer.

VCC: the power supply of the 16×2 LCD connected with a 5V pin in Arduino.

In this picture down below you will see a 16X2 LCD pinout diagram and the pin configuration.

It’s easy to use and programmer-friendly.

It’s available in educational resources.

It is called 16×2 because you can display 16 characters in one column and it has 2 rows so, in total, you can display 32 characters on it.īut why is it commonly used in many applications? 16×2 LCDĪ 16×2 LCD size is the most commonly used in the applications of embedded systems. The LCD (Liquid Crystal Display) is an electronic screen mainly made from Liquid Crystals, there are many sizes available such as 16×2, 16×4, 20×2, 20×4, … 40×4.īut in this Tutorial, we will use this 16×2 LCD size because it is a basic size and commonly used in electrical circuits which we will take about shortly.
