The ESP32 development board, which was released as a successor to the ESP8266 chip, made a huge impact on the IoT industry as it integrated Bluetooth with WiFi and utilized a dual-core processor. ESP32-S3 is the latest addition to Espressif's microcontroller series, specifically designed for AIoT applications. In this video, we will look into the specifications of ESP32-S3 and its applications. Espressif announced the ESP32-S3 microctroller on 1st December 2020. It features a dual-core Xtensa LX7 CPU, while its previous iteration, the ESP32-S2, was based on a single-core Xtensa LX7 CPU. The S2 model was considered a bridge between the ESP8266 and ESP32 microcontrollers regarding performance and cost.Will guide you through making your first internet-connected electronics project using a Wi-Fi breakout ball that is available almost everywhere. You will study the complex workflow of hardware and software that makes smart objects successful through basic examples of step-by-step. We will take examples of the most common things you want to wake up, such as sensors or buttons that trigger email or tweet. We will also take examples of circuits that display FITCHETT information online and how to combine sample codes to build your project ideas. So whether you are a software engineer just dipping it at all into hardware or beginners who only have basic knowledge and Arduino, you will explore the Cloud service to quickly and easily link your DIY circuit with other Internet Things devices, social media websites and A more. The Internet of Things is now a trending topic, so I strongly recommend that you join this reason to get the knowledge you need to start as a freelancer IoT or just to start your career on the internet.
