What Is LCD Interface And How It Works?
LCD means Liquid Crystal Display. What we can see on the serial monitor, also can be seen on LCD. There are mainly two types of LCD: 16x2 and 20x4. 16x2 means, 16 characters per line by two lines and 20x4 means 20 characters per line by four lines.
If an 8-bit data bus is used, the LCD will require 11 data lines. In that, eight lines are for data bus, and three lines are for control. There are three types of control lines- EN, RS, RW.
EN= Enable (for sending data)
RS= Register Select (treat data as command or text)
RW= Read/Write (read/write data to LCD)
In the video, pins and configuration of LCD is explained with LCD diagram.
Now create a circuit on tinkercad using steps shown in the video. First, Connect LCD with Arduino. Then start coding. Copy program and paste it into tinkercad. Compile it and see the results.
You can change your character spacing in LCD as shown. Learn new ways of writing in LCD from the video. This way, you can interface LCD and display whatever you want to show.
