Description :

2012 latest IIC LCD2004-character LCD display module, a new high-quality 4 line 20 character LCD module not only set the contrast control knob selector switch also has a backlight and IIC communication interface. For Arduino beginners, not for the cumbersome and complex LCD driver circuit connection and a headache, the real significance of this LCD module will simplify the circuit, this module directly into the Arduino Sensor Shield V5.0 sensor expansion board IIC device interface can, GM 4P sensor connection cable, programmed through the Arduino controller, you can easily identify the slogan, sensor data records

Specification:

  • Interface: I2C
  • I2C Address: 0x3F
  • 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

Arduino Test Code:
#include <Wire.h>
#include <LiquidCrystal_I2C.h>

LiquidCrystal_I2C lcd(0x3F,16,2); //set the LCD address to 0x3F 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);

Struggled to get it working on the LeonardoReview by JIK

I eventually got this LCD working on the Leonardo with the following . h file which i obtained at arduino-info.wikispaces.com/file/detail/LiquidCrystal_I2C2004V1.zip

does anybody know if this is the latest file available as t was posted in 2012. (Posted on 3/24/14)
Works fine, but example code is out-of-dateReview by Mike

The setup call in the example code needs to be changed to the following for the sketch to work with the Malpartida Liquid_Crystall_I2C library.

LiquidCrystal_I2C lcd(0x3F, 2, 1, 0, 4, 5, 6, 7, 3, POSITIVE); // Set the LCD I2C address
//LiquidCrystal_I2C lcd(i2c_addr, en, rw, rs, d4, d5, d6, d7, BACKLIGHT_PIN, POSITIVE); // Set the LCD I2C address

Also change the lcd.begin call to the following.
lcd.begin(20, 4, LCD_5x8DOTS); // initialize the lcd

Hopes this helps people.

Address has changedReview by Raj

I had to use an updated LiquidCrystal_I2C library because the older library they have linked doesn't work with the latest editor. Also, I used the I2C scanning program (google for it) and found that the LCD device address was 0x27, which when you shift to the left by one bit, resolves to 0x4E or 0x4F. Seems like they may have changed the device address to 0x4F in the last year.

Unfortunately, even after figuring that out, the LCD now powers up but I can't seem to write anything to the display. Still working on that part. (Posted on 12/29/13)

Bill was spot on - seems like a good device, but as it usually goes, code and examples don't work. I am still trying to get this thing going. I wish vendors would pay more attention to details rather than just trying to sell stuff. Not very happy at all. (Posted on 12/4/13)
Good device, crummy instructionsReview by Bill

It took me a while to figure this out. I am new to arduino and LCDs so it is expected to be harder. I am using an arduino uno. My problem was figuring out the pins. I found numerous examples that showed different pins used.

Ultimately, I followed Eric's example from above and used the I2C scanner and then tested out the various pin locations until I the LCD was recognized.

Like Eric, the software came up with the address 0x3F so that has to be changed in the code sample. The BYTE keyword is no longer valid, but to make the code sample above work, simply delete the word BYTE and the comma that precedes it where ever you see it. Lastly, make sure that you download and install the custom library and header files LiquidCrystal_I2C. The link is below the sample code above called LCD2004. Look on the arduino site for instructions for how to install custom libraries if you need help on that.

For the UNO, connect the pins as follows:

LCD -- UNO
SDA - A4
SCL - A5
VCC - 5V
GND - GND

Works like a charm. (Posted on 12/1/12)
Great LCDReview by Erik

Worked great, using only 2 wires is very nice.

The I2C address wrong in the docs, but I ran the I2C scanner from the Arduino website and it showed the address as 0x3F, plugged that into the examples an everything worked perfectly.

Thank you! Nice looking LCD. (Posted on 10/16/12)

Can someone please document how this thing works?? It seems like a nice product, but there isn't a PDF available explaining how it works. The sample code only helps so much and only if you are using Arduino. (Posted on 10/6/12)

You can waste a lot of time trying to get one of these to work.
There is a multitude of scripts out there , not one of them work including the one offered on this page. (Posted on 9/8/12)
I make a good choice!Review by Solomon

I2C interface, this permits interfacing with only two wires (SDA/SCL) plus ground and 5-volts.SainSmart.com provides its own version of the Arduino LiquidCrystal library and some example code for this particular board. They are not of much help, but it is a nice display, though. (Posted on 7/16/12)
