I2C Communication with an Arduino Alex Lange ECE 480 - Design Team 3 November 13, 2015 Executive Summary: Arduino is an open-source microcontroller perfect for prototyping or hobbyists. To use the LCD Nanoshield, we provide an Arduino library that allows you to easily control the LCD using only two I/O pins of the I2C interface. Library Example. Connect the CL and XX just like you do with other I2C devices with the Arduino. So we need to install an external library.
