Nice, so I have an LCD so I just want to add the i2c backpack but does the i2c need to be soldered? At 1:30, doesn't look like it's soldered but just asking :)
Thank you very much :)
thank you so much!!
Thanks for support!
Guys, 0x27 is the address of the l2c used in the VIDEO ONLY. Please use l2c_scanner.ino to find YOUR l2c-adress - or try the address 0x3F, which seems to be common.
0x27 is just a default address.
Different I2C modules also will have different addresses.In addition, you can also change the address by wiring A0A1A2 in different ways. For more details, refer to the user manual.
Thanks! ... but my god.. at 4:19, put `lcd.init()` on a NEW line without the curly bracket! And after `lcd.backlight()`, put the closing curly bracket on a new line!
And similar problems in the loop. It works the same but having clean code is very important
Is there code to integrate it with a Real-Time Clock circuit on an Arduino Uno R3?
Please check in this link learn.sunfounder.com/
Do you have the code written down somewhere>?I just want to cut and paste it and then tweek it in. My eyesight is blurry to begin with and trying to read off a blurry youtube does'nt help.
Please check this link:learn.sunfounder.com/category/rfid-kit-v2-0-for-arduino/
Hello! I have display but i have 18 terminals from my dislpay.Have can i connect 18 ports to arduino?
Dear BAGY,
What you have said the 18 ports should be 16 ports. And the LCD1602 didn't have the I2C.
The detailed connection you can watch this video:
th-cam.com/video/VpPEG6mPadU/w-d-xo.html
If you still have problem, pls connect with me.
tank you
Nice video, i want to create characters but i do not understand how it works, and the generator don't do this job. Thanks

Hello, I have a question
When I upload the code I get this error:

I would really appreciate some help
Thanks
aussiecubing You need to unzip the LiquidCryStal I2C file to your libraries folder under Arduino.
Ok thanks
+Sunfounder I have the same problem except im on windows 10 and running Arduino 1.6.7. I went to the libraries folder under arduino in my program files (x86) and there was no zipped "LiquidCryStal I2C" file, but there was an unzipped "LiquidCrystal" file?????
I need help please
+Awesomepieman32 Actually you need to add this library for use. Please go to www.sunfounder.com/index.php?c=case_incs&a=case_nr&type=47 and download the package RFID Kit V2.0 for Arduino.zip on the page. After unzipping, you can see a LiquidCrystal_I2C folder inside. Just copy the folder to the path of your Arduino. Then it should work.
Thanks so much, works now!!
Using the arduino Mega, all connections are correct, LCD back light turns on but I get no black rectangles or words, I am at a loss as to what could be wrong. Tried redoing the library, tried redoing the circuits, code is copied and pasted, the address is correct. Only thing I can think of is that the library pins need to be changed for the mega 2560 for SDA and SCL but I don't know where to change that in the code
it's the wiring actually, which is different for Uno and Mega. For Uno, it's A4 and A5; but for Mega, you need to connect pin 20 and 21 to SDA and SDL of the LCD. See if it works.
I have that all wired correctly
OK. then when you uploaded the code, did any error message appear? if it's uploaded successfully, try spinning the blue potentiometer on the LCD back.
Everything uploads fine which is is the odd part. I will take a look at the contrast tomorrow again but I tried that as well yesterday
you may refer to the FAQ for the I2C LCD1602 on our WIKI page: wiki.sunfounder.cc/index.php?title=LCD1602/I2C_LCD1602_FAQ. If these still cannot help you, you may post forums on our website and post your code and wiring photo so we can help you check what's gone wrong.
I have a question, I wired the arduino like in the video and use the library pasted on the site but when i try to upload the example "hello world" the lcd doesn't change. I tried pressing reset and checked the wiring but everything looks correct.
Which Arduino board do you use? Uno, Mega2560? And is the code uploaded successfully (at the bottom on the window you can see a prompt message for upload done or errors happen)?
uno and it sends the data says upload done but the lcd dosnt do anything.
When you just power the circuit, did the LCD light on? And white checks were displayed instead of what you intended it to? It can be that the I2C address is not 0x27. You need to find the real one out by a code. Copy the code here (www.sunfounder.com/forum/faq-i2c-lcd1602-not-displayed/#simple-forum-post-217) in a new IDE window and upload it to your board. When it's successfully done, open Serial Monitor and the I2C address will be displayed then.
Then replace the address in this line in your code: "LiquidCrystal_I2C lcd(0x27,16,2);" with the one you just get.
It WORKED! thank you very much
Glad to help! :) If you have more questions, welcome to check FAQs or other forums on our website.
what is the name of pendrive like device
Can I control C12 LCD with my Arduino mega?
If you are talking about i2c, then you can. It should be noted that the i2c pin position of arduino mega is different from that of arduino uno.
Hello, i keep having this problem "
In function 'void loop()':
big_idea:24: error: 'positionCounter' was not declared in this scope
for (int positionCounter0; positionCounter
There is a "=" missing in the scope (int positionCounter0; positionCounter
thank you very much !!!
Our pleasure. Welcome to post forums on our website www.sunfounder.com if you have any questions!
I have tried over and over the scanner code and it just display the 16 black rectangles on line
Hi Selena,
The scaner code is just use to detect the address of the I2C LCD1602, you need to use the additional code.
Below link code for your reference to.

Have a good time!
im buying sunfounder kit ;)
Great kit. Glad it was my first. Make sure to install program and libraries as they recommend. I kind of got that part wrong
Dear Ricky,
Thank you so much for your support!
Have a nice day!
I get this error:
avrdude: stk500_recv(): programmer is not responding

+William Ahlgrim For this error, you may check solutions in WIKI of our website, at www.sunfounder.com/index.php?c=downloadscs&a=Manualdetails&id=81&name=Solutions%20to%20Problems.
If you still cannot figure it out, you may try post on our FORUM and we'll help you solve it out.
i have a problem
the code dose not work
backlight dose not change its color
please help
Dear Alrawahi,
Pls checked the pins GND,VCC on the I2C LCD1602, whether the cables are reversed. If not, then check the I2C in the back of the LCD. In the side of the I2C module, there is a cap. If it has been pull out? It's used to be powered for the backlight. If yes, the backlight will be not show.
If you still can't find the way to solve it. pls connect with us asap.
Good luck!
#include makes a error: "No such file or directory" please help
You need to add LiquidCrystal library first. You can download it at the bottom of the page: wiki.sunfounder.cc/index.php?title=I%C2%B2C_LCD1602

Where did you get the LiquidCrystal_I2C library? The problem is a conflict between your library and the code we provide. You can download the library again at the bottom of this page: wiki.sunfounder.cc/index.php?title=I%C2%B2C_LCD1602. And try again. It should work. Seems like Frits below had the same problem and fixed it this way.
Hi Folks,
So I followed everything as best I could. I copy and uploaded the code from the wiki. wiki.sunfounder.cc/index.php?title=I%C2%B2C_LCD1602
I followed the instructions and was told the code uploaded. However, after the screen on lcd went blank for a moment, it just came back on again in blue and that was it. No message.
Any ideas?
Hi, could you mail us a picture of the wiring connection between your UNO and this LCD module? and we will help you there. The mail: support@sunfounder.com.
So I upload the sketch and the screen is just blank. Well the top row has dark squares and the bottom row is blank...
+Ashley Perry Try press the reset button on the control board.
+Sunfounder Wow thanks for the fast response! I've pressed the reset button and powered it off and on again and still doesn't work. I've noticed the L LED is blinking quite a lot too. I assume the sketch has been uploaded as the tx/rx LED flash while it's uploading
+Ashley Perry Actually when the code upload is almost completed, the LED will blink for a while. When upload is done, it will stop.
For LCD not working, first you may check whether the wiring is correct. What control board do you use, Uno, Mega2560 or others? If you use a Mega, the SDA of the I2C LCD should be connected to SDA (20) of the Mega, SCL to SCL (21).
If this still doesn't work, post screenshots of your code uploading results and physical wiring photos on our website Forum or send email to support@sunfounder.com
It turns out i had installed the library in the wrong location. LCD screen is working fine now, thanks!
Oh, always the library...so now you can have fun with the LCD.
For more details, you can check our FORUM and WIKI, where we'll release more and more interesting and useful tutorials for you to better learn. And, welcome to share with us your study notes, which may be great help to other hobbyists!
No such file or directory problem !!!! Help.
Does make error? If so, you need to add LiquidCrystal library first. You can download it at the bottom of the page: wiki.sunfounder.cc/index.php?title=I%C2%B2C_LCD1602
lcd.init(); error saying web_lcd_test:9:12: error: 'int LiquidCrystal_I2C::init()' is private within this context
Please use the library we provide:wiki.sunfounder.cc/index.php?title=I%C2%B2C_LCD1602 .

I am trying to add a flowmeter to an lcd. All I am getting is a bunch of weird characters in my display any ideas how to get real values from the below code?
#include
#include
#include #define I2C_ADDR 0x27 //
Dear MGDNation,
Feel so sorry that we haven't provide the flowmeter and the "an lcd." head file , therefore, we can't help you to adjust your code. We suggest that you can find the usage method of the flowmeter.
If you have other technology problem, we will try our best to help you!
Mine complies and uploads but then its just a bunch of squares on the screen
Any further help,please contact service@sunfounder.com
Nothing happens when I have uploaded the sketch. The LCD screen is just blue
Have u adjusted the Potentiometer behind the LCD Screen to adjust the Brightness and check for the required display?
same problem
Library does not work. It is already obsolete.
Dear Lucas,
Could tell me what kind of kit you bought? Pls send us a link.
And which library you used?
Waiting for your reply!
Dear Lucas,
Where did you download the library?
Or you can try the below link:
wiki.sunfounder.cc/index.php?title=I%C2%B2C_LCD1602
It was exactly this library I used.
For those who are having issues using Sunfounders source material:
Go to this website
bitbucket.org/fmalpartida/new-liquidcrystal/downloads/
Download version 1.3.5
go to your Arduino software and add the library.
Write as following:
#include
#include
LiquidCrystal_I2C lcd(0x27,2,1,0,4,5,6,7,3,POSITIVE);
void setup(){
lcd.begin(16,2);
lcd.clear();
lcd.print("Hello World");
}
void loop()
{
}
The First bit of code is just to get the LCD handshake initialized with the Arduino software, from there you can add any other details you want.
Happy Coding!
For those who are struggling with the "exit status 1" error, you need to download the new library file for LiquidCrystal I2C.
You can do this by downloading it off of the Arduino-Library on their website, here's the link below:
www.arduinolibraries.info/libraries/liquid-crystal-i2-c
Once you downloaded the zip folder you can then go into Arduino and open the source code that was provided by Sunfounder for project 4. Then *this is the important step* go to ("Sketch"-> Include Library-> Add Zip. to the library) Load the zip file "LiquidCrystal I2C" that you just downloaded and then load the library into the existing code ("Sketch"-> Include Library-> Manage Libraries). Upload the program and the LCD screen should work properly.
Good luck everyone!:)
Thanks for sharing!
too small... i can't read what u write

Even if i didn't put any library called Wprogram.h so i don't understand why they put this error :/
Sorry for words that are in french.
Thanks to reply. :).
Dear MP，
What version of the IDE you use? We suggest that you use the latest version of the Arduino IDE.
If you still have trouble, pls connect with us!
I have fixed the problem ☺ now its fine. But the links you put in description isn't working fine. If you can do something about it too.
Dear MR,
Wow! Great!
But we can't find the link you said in the description.
Have fun!
Hi Sunfounder.
With the latest IDE I had the same problem "failed to find Wprogram.h". The old .ccp file needs to updated with this link; gist.github.com/jrmedd/5516863
I did this with my project and it solved the problem. You may have to do this with your ".ccp" project file to get it to work. Hope this helps
