Introduction: Arduino I2C 16*2 Lcd Display Connection

I²C (Inter-Integrated Circuit), pronounced I-squared-C, is a multi-master, multi-slave, packet switched, single-ended, serial computer bus invented by Philips Semiconductor (now NXP Semiconductors)

Step 1: Parts ....

Picture of Parts ....

* Arduino Uno

* 16*2 Lcd Display

* I2C Breakout

* Male - Female Jumpers

Step 2: Wiring .......

Step 8: Finding the I2C Address ....

Picture of Finding the I2C Address ....

To Find Your I2C Address First Upload This i2C Scanner Code & Open The Serial Monitor Then You Will Get A Code Like This Unplug Your Arduino Cable & By Using Cntrl + C Copy The Address

After getting the I2C Address , Include The Library

After That Get The Arduino Code

And Paste The Address Over There , To Make Your I2C Communication Easier With Arduino

Then Upload The Code .

Please help me. I followed the tutorial but it says," 'POSITIVE' was not declared in this scope.

SreeR18 (author)MichaelL5712017-04-04

delete the "POSITIVE" and run the code again

Did U Used The Library Which I Had Given ??

Thank you, it works. Other manuals on the Internet has some problems (more different libraries, different constructor and etc.) I used inbuild library in Arduino IDE (need to instal via Arduino IDE).

Thats nyz to hear from you my friend.... Good luck ☺
