Description

Easily control an LCD screen with only 2 wires and this I2C controller

The I2C backpack allows you to easily control an LCD screen using only two Arduino pins (A4 and A5 of the I2C bus). It's a very useful tool given the very limited number of pins on an Arduino Uno. If you have already connected several sensors to your Arduino, you'll not have enough pins left to control an LCD screen ... this I2C breakout will be your savior.

The standard HD44780 displays are really useful for creating stand-alone projects, however they require many pins if you interface them directly with an Arduino platform.
Here we propose this backpack which allows you to control HD44780 compatible screen like our 2 lines white/blue screen (or the 4 lines screen of this product). 

Using an I2C LCD screen is a great Arduino project, a good introduction to I2C and a useful tool for your future projects.

The great thing about the I2C bus is that you can have other I2C devices on the same bus (without consuming more pins). You can even use several LCD screens on the same Arduino because this breakout has address pins (to change the address of the breakout on the I2C bus).

Thanks to the LiquidCrystal_I2C Arduino library, taking control of this screen is really child's play (see Tutorial section). The library supports the I2C 1602 interface. Tested and approved by MCHobby.
