Tutorial: I2C Bus LCD Display controlled with the Arduino

[beehive]

Great video, Thank for help me understanding the right way to program the Arduino and using other hardware

Beautiful! Very useful and correct information!

[Makecourse]

Are you using the sketch and the  library posted at makecourse.com? There are several ways to run LCD displays. If you use the standard LCD library in the Arduino software, the I2C LCD display will not work with it.

hi!, I have a problem with the I2c bus lcd because I followed your steps, even I download the library from the arduino site. But when I load the code, it doesn't send the "hello world" to lcd. Could you help me?

hi...i had a problem if i type
lcd.print("hello world");
the lcd display only the first word of hello world...so on the lcd i see only one h... how can i solve it?

It would be useful to post a link to the correct version of LiquidCrystal_I2C.h as Google comes up with too many. I have not yet found a working one, my hardware is exactly like that in the video.

I have hooked everything up correctly and made sure to triple check it and the code is uploaded but all it does is light up for a little bit and reset. The words never appear
