Download Udemy – Home Automation with ESP32 and Google Home 2024 2024-2

• In the first part, we will explore the importance of home automation and how it can increase convenience and security in our daily lives. We will then turn our attention to the remarkable ESP32 board, which plays an essential role in the development of our project. After that, we will understand the general I/O pins of the ESP32. These pins act as the critical interface between the ESP32 board and the external realm, allowing for seamless connectivity with an array of sensors and actuators. With a deep understanding of GPIO functionality, a world of endless project possibilities awaits you.
• In the second part, our focus will shift to understanding the hardware requirements necessary to build the project. We start by turning on the ESP32 board and identifying the specific USB-to-UART chip integrated into the board. Moving forward, we will continue to install the integrated development environment (IDE) and configure the board manager library designed specifically for the ESP32. This step is very important because it enables us to create a suitable software environment for programming and interacting with the ESP32 board. Once the IDE is successfully launched, we proceed to install the necessary drivers for the USB to UART chip and ensure seamless communication between the board and our computer. All things considered, we test the performance of the board using a basic program. This essential test helps us determine if our recently purchased ESP32 board is working as we want.
• In the third part, we will focus on exploring the fascinating world of relays and gaining a deep understanding of their working principles. Once we get the basic concepts of relays, we move on to study the circuit diagram for controlling a home appliance using relays. Then we run the circuit diagram and write the necessary code to program the relay to control the connected electrical devices. This practical approach enables us to gain practical experience in relay circuit implementation and enables us to use their potential effectively. By the end of this section, you will be well equipped to use the capabilities of relays in real-world applications.
• In the fourth part, we will focus on addressing the issue of reverse relay operation and exploring different solutions to fix this problem. We turn to the domain of programming and explore a logical implementation that can efficiently solve the problem. Using our programming skills, we will develop strategies to ensure that the relay functions in the desired manner. In addition, we will also explore alternative approaches to reduce the reverse relay performance by modifying the circuit wiring. Through careful investigation and testing, we will discover alternative wiring configurations that can fix the problems and match the behavior of the relay to our desired performance. By examining programming-based and wiring-based solutions, you will gain a comprehensive understanding of the options available to solve reverse relay operation. This knowledge enables you to choose the most appropriate approach based on your specific needs and limitations.
• In the fifth section, we will introduce an additional function to our existing circuit. We insert a physical switch and use its input to control the behavior of the relay. By integrating this switch, we can increase the interaction and flexibility of our circuit. Initially, we will focus on understanding how to effectively read input from a switch and develop the code logic necessary to control its operation. Once we’ve mastered this process, we’ll expand our coding skills to include the remaining three relays in our circuit. This extension enables us to control multiple devices simultaneously based on the input of their respective switches. Through this exercise, we not only refine our coding skills, especially in the areas of decision-making and logical thinking, but also gain insights to build collaborative communication across circuits.
• In the sixth part, we will discuss the world of Internet of Things. We will learn about the concept of Internet of Things and its importance in connecting and controlling devices through the Internet. After that, we’ll explore the cloud platform that serves as the backbone of our project and allows us to effectively harness the power of the Internet of Things. In addition, we will also learn about the basic MQTT protocol that facilitates communication and data exchange between our devices and the cloud platform.
• In the seventh part, we will start developing our main project. We start by studying the circuit diagram and understanding its components and connections. With this understanding, we will design and assemble the circuit based on it and ensure its correct operation. Then we will review the source code that allows us to control all the devices remotely. We will gain valuable insights into how data is sent to the server and retrieved based on user choices. We will also analyze how data is synchronized between the cloud platform and physical input by the user. In addition, we will also examine the concept of powering the entire circuit using an external power adapter. This approach simplifies setup and increases convenience, providing a reliable and efficient power source for our project.
• In the eighth part, we will show the practical output of our main project. We will use both mobile apps and handheld switches to control the devices in real-time and provide a hands-on demonstration of their functionality. Additionally, we’ll explore how to integrate and control devices seamlessly through Google Home, allowing for effortless control via voice commands. This integration improves the overall user experience and provides greater convenience and simplicity in managing connected appliances. Finally, we will demonstrate an additional feature of our project that ensures uninterrupted control of home appliances even when the user’s Wi-Fi connection is unavailable. In such cases, users will have the option of relying on manual switches for effortless operation and management of all connected appliances. This dual-mode functionality provides a reliable backup solution, ensuring convenience and accessibility at all times. Each video in this course teaches you new concepts and techniques that you can immediately use in any of your projects. This course only covers basic programming knowledge and you can leave the rest to us. So if you’re someone who has never built an embedded systems project before, don’t worry, I’ll be with you every step of the way.
