Thanks for this instruction video. I have also been struggling with several other RUclips instruction videos without succes. Following your procedure, it worked immediately. I guess it was having the right type of library is important and also the use of the variable resistor in the back is important.

Hello! I followed your steps accordingly, turned the potentiometer knob at the back of the module to both sides but no characters are being displayed, just the green light of the LCD. Do you have any suggestions?

I am facing problem with , it shows me error compiling for board arduino/uno , but i hav done all steps which u hav shown and also included new library also . But got output for i2c address scanner in serial monitor
Thanks for the video! When I try to connect the I2C to the Arduino, The Arduino shutes down and gets very hot when I connect the gnd to the ground, and the vcc to 5V. Is there anything that I can do?
Aviel Eliyahu check the i2c module if u have any shots it only happens if u have any short wirings that leads to the arduino ... it can even damage the arduino permanently .... or The I2c Lcd Backpack which u have is a damaged one these are the possible reasons
Look at the I2C LiquidCrystal folder in your Libraries folder and look at the spelling of the folder name. If it is spelled "LiquidCrystal_I2C" it is the wrong library for the display code you are using. You need fm's library from here : bitbucket.org/fmalpartida/new-liquidcrystal/downloads When you remove the old library (you can't just rename it) and install fm's library , the new library folder name will be "LiquidCrystal" , NOT "LiquidCrystal_I2C".
I've tried the same way but there is error message: positive was not declare in this scope. Whats wrong with my code? I've been adding the newliquidcrystal library from fmalpartida bitbucket too
Please use this library magnusglad.se/LiquidCrystal_I2C.rar & try to change the old library from the C - Documents - Arduino - Library Completely which you were included ........... & If the error arise again please check the i2c address check i2c address of the lcd backpack with this code upload the code to arduino and open the serial monitor to find the correct i2c address www.mediafire.com/file/f7oaa4et779yaaz/i2c_scanner.ino

This can be common. An assumption is that tabs are for new sketches. But they only open another file for some more code; for the same sketch. Meaning you only declare void setup() and void loop() once. So you may have declared this more than once leading to this error.

mine has error. it says "redefinition of 'void setup()'"
Do you have two tabs in your sketch? When you drag things into the environment, it adds it to the current sketch when you may want to simply open it.
This can be common. An assumption is that tabs are for new sketches. But they only open another file for some more code; for the same sketch. Meaning you only declare void setup() and void loop() once.
So you may have declared this more than once leading to this error.
oooh okay. so, 1 sketch only at a time?
yup
