Giới thiệu Mô Đun Arduino Uno IIC I2C TWI Serial 2004 20x4 LCD Cho Arduino Uno Mega2560 tại Lotte Market

Description:

This is IIC Serial 20X4 LCD module . With this I2C interface LCD module, you will be able to realize data display via only 2 wires. If you already has I2C devices in your project, this LCD module actually cost no more resources at all. It is fantastic for for arduino based project.

Specification:

Interface: I2C

I2C Address: 0x20

Sofware version :0022

SDA (DATA) -> analog input pin 4

SCL (CLOCK) -> analog input pin 5

Pin Definition : GND.VCC.SDA.SCL

Back lit (Blue with white char color)

Supply voltage: 5V

Pcb Size : 60mm×99mm

Contrast Adjust : Potentiometer

Backlight Adjust : Jumper



Test Code for Arduino:

#include
#include

LiquidCrystal_I2C lcd(0x27,16,2); //set the LCD address to 0x27 for a 16 chars and 2 line display

void setup()
{
lcd.init();
lcd.backlight();
lcd.setCursor(0, 0);
lcd.print(”b2cqshop”);
lcd.setCursor(0, 1);
lcd.print(”Voltage: ”);
lcd.setCursor(13, 1);
lcd.print(”V”);
}
void loop()
{
int val;
float temp;
val=analogRead(0);
temp=val/4.092;
val=(int)temp;//
lcd.setCursor(9, 1);
lcd.print(0x30+val/100,BYTE);
lcd.print(0x30+(val%100)/10,BYTE);
lcd.print('.');
lcd.print(0x30+val%10,BYTE);
delay(100);
}
