By makertechno

interfacing 16x2 lcd with arduino

Liquid crystal display is a very essential part in all embedded devices form claculater to printing machines,LCD workes with voltage pluses ,with two are more kind of ic drivers in lcd display form lcd module.

Step 1: Interfaceing

Step 2: Code

#include // initialize the library with the numbers of the interface pins

LiquidCrystal lcd(12, 11, 5, 4, 3, 2);

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 the number of seconds since reset:

lcd.print(millis()/1000);

}
