LiquidCrystal()

[LiquidCrystal]

Description

Creates a variable of type LiquidCrystal. The display can be controlled using 4 or 8 data lines. If the former, omit the pin numbers for d0 to d3 and leave those lines unconnected. The RW pin can be tied to ground instead of connected to a pin on the 86Duino; if so, omit it from this function’s parameters.

Syntax

LiquidCrystal(rs, enable, d4, d5, d6, d7)
LiquidCrystal(rs, rw, enable, d4, d5, d6, d7)
LiquidCrystal(rs, enable, d0, d1, d2, d3, d4, d5, d6, d7)
LiquidCrystal(rs, rw, enable, d0, d1, d2, d3, d4, d5, d6, d7)

Parameters

• rs: the number of the 86Duino pin that is connected to the RS pin on the LCD
• rw: the number of the 86Duino pin that is connected to the RW pin on the LCD (optional)
• enable: the number of the 86Duino pin that is connected to the enable pin on the LCD
• d0, d1, d2, d3, d4, d5, d6, d7: the numbers of the 86Duino pins that are connected to the corresponding data pins on the LCD. d0, d1, d2, and d3 are optional; if omitted, the LCD will be controlled using only the four data lines (d4, d5, d6, d7).

Example

#include <LiquidCrystal.h>
 
LiquidCrystal lcd(12, 11, 10, 5, 4, 3, 2);
 
void setup()
{
  lcd.begin(16,1);
  lcd.print("hello, world!");
}
 
void loop() {}
