Liquid Cristal Display Using Arduno

LCD (Liquid Crystal Display) is a type of display media that uses liquid crystal as the main viewer.

In this article I will use a 2x16 LCD. Because this type of LCD is mostly found on the market.

Specification:

• Physical form, see picture
• Number of columns = 16
• Number of rows = 2
• Operating voltage = 5V
• Equipped with a back light
• The back lights are yellow

Components needed in this tutorial:

• LCD 2x16
• Arduino Nano
• Jumper wire
• Project Board
• USBmini

Library needed:

• LiquidCrystal

The "LiquidCrystal" library doesn't need to be added anymore, because it's already provided by Arduino IDE

To install a 16x2 LCD, you can see the information below:

• LCD RS ==> D12
• LCD E ==> D11
• LCD D4 ==> D5
• LCD D5 ==> D4
• LCDD6 ==> D3
• LCD D7 ==> D2
• LCD RW ==> GND
• LCD VSS & K ==> GND
• LCD VDD & A ==> +5v
• LCD V0 ==> PullDown 10K Resistor

Arduino IDE already provides an Example for those who want to learn to use Arduino.

To open a sample sketch for the LCD, the method is as follows:

• Open the Arduino IDE
• Click File > Examples > LiquidCrystal > Hello World
• Connect the Arduino to the Laptop, then upload the sketch.

the results are as follows:

The first line appears "hello, world!"
And in the second row there is a counter.
