Course Description

>>> Start Sending Data Over Long Distance using Arduino via Wired and Wireless Connection and extend Arduino Capabilities <<<

Welcome to this course.

This course will teach you how to make long-distance communication between two Arduino boards using wired and wireless connections. This guide will take you step by step to understand the needed components, why we use them, and how to wire them up, starting with the basics of Arduino Serial Communication and ending with sending data over a very long distance.

You will learn the actual working principle of long-distance communication, the right communication protocols to use, and how to interface the required module to make this happen.

We know that Arduino has several built-in buses for fast data transfer, such as the SPI Protocol and I2C Protocol. Various kinds of sensors are often connected using the I2C communication protocol. There is also the popular UART (Universal Asynchronous Receiver Transmitter) protocol, often used with a USB interface to exchange data with a laptop or computer. But all of these methods have a serious drawback: they do not work at large distances.

Imagine a situation where we need to collect data from sensors on the roof of our houses and, depending on the location of the sensors, our hardware, and software setup, we need to transfer a signal from this sensor to our Arduino on the first floor. How can we make it possible? We'll definitely need a powerful long-distance transmission method, one that can be used for years, and in this course, we will cover this. We will cover wireless and wired long-distance communication methods between two or three Arduinos or any two microcontrollers, whether they are Arduino microcontrollers or any other types of microcontrollers.

We will make it as simple as possible.

Why You Should Take This Course:

  • Extend the capabilities of Arduino

  • Use wireless communication for more flexible Arduino projects

  • Send data wirelessly in Arduino projects

  • Create a wireless sensor network

  • Send data over long distances wirelessly or via wired connection

What You Will Learn in This Course:

  • Learn the hardware required to make this happen

  • Understand RS485 and how to implement this communication protocol in long-distance communication

  • Create a schematic for connecting two Arduinos using the RS485 protocol over long-distance

  • Discuss the receiver and transmitter program for RS485

  • Understand the circuit assembly and break down the HC-12 module working principle for long-distance wireless communication between two Arduinos

  • Perform communication between Arduinos using the HC-12 module

  • Explain how communication works with Arduino transceiver
