Good display. You need to set the potmeter to see characters. First run a program to display characters. I used library https://bitbucket.org/fmalpartida/new-liquidcrystal/downloads Instruction for installation of that library http://arduino-info.wikispaces.com/Arduino-Libraries#NewLib Finally an example program can be found at http://arduino-info.wikispaces.com/LCD-Blue-I2C the last program, only modified it for address 0x27 and 16 x 2 characters For all library routines have a look at your library documentation, in my case C:\Arduino\arduino-1.05\reference in file LiquidCrystal.html

Hi all - I used the banggood recommended library: https://app.box.com/s/dl5ntat7o0f3okee9suo though the example hello world didn't work at first. I used I2C scanner (http://playground.arduino.cc/Main/I2cScanner?action=sourceblock&num=1) which detected it at address 0x3F rather than the documented 0x27 default (and 0x20 setting in the example code!). just correct this line in the example and it works great!: LiquidCrystal_I2C lcd(0x3F,16,2); // set the LCD address to 0x3F for a 16 chars and 2 line display Thanks!

So here it is, for all the noobs like me: 1. Connect the screen with SDA to A5 (Arduino UNO) SCL to A4 2. Go to http://playground.arduino.cc/Main/I2cScanner Copy the scanner code and run it. Get the adress . Mine was 0x3F. 3. Get the New Liquid Crystal Library at https://bitbucket.org/fmalpartida/new-liquidcrystal/downloads. 4. Include these libraries in your sketch: #include #include #include 5. Copy and paste this code: #define I2C_ADDR 0x3F // <<----- Add your address here.

Came as described, fast from EU warehouse. Got it working pretty quick after a few guides and how to setup (never played with I2C or LCD screens before). With the library for arduino I found it's easy to use once setup done. As many others it arrived out of focus, need to adjust the potentiometer on the back - also I was a bit confused why it didn't seem to work when connecting the arduino to computer (1 full line of black squares, one blank line)... But opening serial monitor (if a serial is set in the code) or uploading code seems to reset it. Connecting arduino to a powersource (vin) it works normally first time. I guess it's the connection to computer that makes a problem, but uploading code or resetting it with serial monitor starts everything. All in all very pleased, and more will be ordered for other projects. Actually I ordered this for another project but now it's used... Need a new already :) The only thing I don't like is the pins on top of the screen, they are long - but a wirecutter fixes that quick (photo).

مغلفة بشكل سيء، عندما وصلت الدبابيس كانت مثنية، تُعدّل بسهولة بسرعة تسليمها.

Poorly packaged, when it arrived pins were all bent, easily straightened quickly delivered.

Great product, the main advantage is that it is working by utilising the lesser RAM and happy with the product.

إنها شاشة جميلة ومحمية بشكل جيد إلى حد ما مع لف مضاد للكهرباء الساكنة وبعض الفقاعات البلاستيكية للوسادة الإضافية (كما أن الشاشة تحتوي على غشاء واقٍ عليها).

It is a nice display and fairly well protected with an anti static wrap and some bubble plastic for extra cushioning (also the screen had a protective film on it).
