Communication using I2C interface

Inter-Integrated Circuit (I2C) is a chip-to-chip interface supporting two-wire communication. You can connect to I2C peripheral devices and read from and write to them. Using the I2C communication protocol, your Arduino^® board can communicate with microcontrollers and peripherals such as sensors and displays.

Blocks

	I2C Write	Write data to an I2C peripheral device or an I2C peripheral device register
	I2C Read	Read data from I2C peripheral device or I2C peripheral device register

Develop Gyroscope-Based Pedometer Using Arduino

How MATLAB® Function blocks are used in Simulink® models to implement algorithms using MATLAB functions. An Arduino® MKR1000 board is used to count the number of steps a person takes while walking. The pedometer is attached to the thigh of the person in such a way that the x-axis of the gyroscope is perpendicular to the direction of walking. The data from a gyroscope sensor is sent to an Android device using the User Datagram Protocol (UDP).
