How connect LCD jhd162a to Arduino?
Once you are able to connect it to your breadboard, it’s time to wire it all up as per the illustration and instructions below:
- Pin 1 to GND.
- Pin 2 to 5v.
- Pin 3 to GND through a 1k ohm resistor and to 5v through a 10k ohm resistor.
- Pin 4 to Arduino pin 12.
- Pin 5 to GND.
- Pin 6 to Arduino pin 11.
- Pin 11 to Arduino pin 5.
What is the code for the LCD in Arduino?
EN (Enable) pin is used to enable the LCD. HIGH to enable the LCD, LOW to disable the LCD. D0-D7 (Data Bus) pins carries data and command between Arduino and LCD….4-bit mode and 8-bit mode.
| LCD PIN | CONNECTED TO | |
|---|---|---|
| 11 | D4 | An Arduino’s pin |
| 12 | D5 | An Arduino’s pin |
| 13 | D6 | An Arduino’s pin |
| 14 | D7 | An Arduino’s pin |
How does Arduino display data on LCD?
Before wiring the LCD screen to your Arduino board we suggest to solder a pin header strip to the 14 (or 16) pin count connector of the LCD screen, as you can see in the image further up. To wire your LCD screen to your board, connect the following pins: LCD RS pin to digital pin 12. LCD Enable pin to digital pin 11.
How do I use Arduino LCD screen?
The Setup
- Insert your LCD screen into your breadboard vertically such that each pin has its own separate line on the board.
- Insert your potentiometer in the same way.
- Connect 5v and GND from Arduino to the / – rails on your breadboard.
- Connect Pins 1 and 16 from the LCD screen to the negative power rail.

How many numbers of pins a 16×2 alphanumerical LCD has *?
LCD 16×2 is 16 pin device which has 8 data pins (D0-D7) and 3 control pins (RS, RW, EN). The remaining 5 pins are for supply and backlight for the LCD. The control pins help us configure the LCD in command mode or data mode. They also help configure read mode or write mode and also when to read or write.
