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.
- 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
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Required Components
Components needed in this tutorial:
- LCD 2x16
- Arduino Nano
- Jumper wire
- Project Board
The "LiquidCrystal" library doesn't need to be added anymore, because it's already provided by Arduino IDE
Step 2: Wiring
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
Step 3: Programming
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.
Step 4: Result
the results are as follows:
The first line appears "hello, world!"
And in the second row there is a counter.
