Are you finding automation devices expensive? Do you want to create your own Modbus client or server devices? This course will familiarize you with the Arduino development board and teach you how to use the Arduino integrated development environment (IDE) and C programming for creating your own automation equipment.

You will start by exploring hardware devices and software that you will be using in this course. Next, you will learn to use the Arduino IDE to create and run your first Modbus Transmission Control Protocol (TCP) server application and learn how to add code on your application to read a holding register, an input status, and a coil. Towards the end, you will learn to program the Arduino to behave like a Modbus TCP client by configuring the client library in the Arduino IDE and writing the code to read the Modbus register types. You will also learn how to test the expanded Modbus TCP client application.

By the end of this course, you will have all the skills needed to create your own Modbus TCP/IP client and server device using the Arduino Uno development system.
