The 16×2 LCD display is an electronic device that is used to display messages and data such as measurements, words, symbols, and more.
In a 16×2 LCD display, the term LCD stands for Liquid Crystal Display. It’s used in an extensive range of applications, like various circuits and devices, like mobile phones, calculators, computers, TV, and others.
In this post, we’ll discover how to use 16×2 LCD display with Arduino, step by step.
Electronic components that we need:
- LCD display 16×2
- variable resistor (Potentiometer 5k Ohm)
- 1 resistor (220 Ohm)
- Electrical wires
- Arduino UNO
- Breadboard
Circuit diagram:
Arduino Programming Code:
// include the library code:
#include <LiquidCrystal.h>
// initialize the library by associating any needed LCD interface pin
// with the arduino pin number it is connected to
const int rs = 12, en = 11, d4 = 5, d5 = 4, d6 = 3, d7 = 2;
LiquidCrystal lcd(rs, en, d4, d5, d6, d7);
// by www.andprof.com
void setup() {
// set up the LCD's number of columns and rows:
lcd.begin(16, 2);
// Print a message to the LCD.
lcd.print("Hello, World!");
}
void loop() {
// set the cursor to column 0, line 1
// (note: line 1 is the second row, since counting begins with 0):
lcd.setCursor(0, 1);
// Print a message to the LCD.
lcd.print("www.AndProf.com");
}
