Arduino Communication: RS-485 Protocol for Long-Distance Data Transmission

Would you like to know how to build your own Arduino long-distance transmitter and receiver? This course contains all of the necessary information to make it a reality. You'll start by exploring software like Arduino and Fritzing and hardware requirements, like the RS-485 and HC-12 modules, Arduino boards, and some connecting wires. After that, we discuss the steps involved in downloading and installing Arduino IDE and Fritzing, two software packages essential for coding and designing circuits.

Next, we explore the Arduino long-distance wired communication while detailing the RS-485 communication protocol and its implementation. We then explain how to design a schematic for connecting two Arduinos using the RS-485 module. We also cover the coding process for enabling Arduino boards to send and receive data. You'll learn some simple code lines for the transmitter program and then for the receiver, including setting the mode of the pins and creating a buffer.

The course concludes by investigating the Arduino long-distance wireless serial communication approach. We go over the HC-12 module specifications and its working principle. After that, we discover the appropriate connections between two Arduinos and two HC-12 modules. Lastly, you'll study how to set up Arduino boards for long-distance data transmission. This course will help you increase your understanding of Arduino capabilities when paired with particular communication protocols.
