Project 03 - Understanding Arduino I2C

This project demonstrates how we can use Arduino I2C for interfacing different sensors. For this I have used Arduino uno as I2C master and Arduino nano as I2C slave. In this project we have controlled LED connected on pin 13 of Arduino nano (slave) from Arduino uno (master) via I2C bus.
