This free online course will help you understand how to use the ESP32 board and Blink app to create an IoT smart garden.

This course will teach you how to create an interactive mobile app interface and connect it to your ESP Board using a free web server. From there, you can control your board directly, receive real-time readings from buttons and sensors, and send control data to pumps, motors, LEDs, and actuators. This course's primary goal is to build an IoT smart garden, but you will also learn to alter the project to suit your needs.

The course starts by discovering our project's main aim, goals, and hardware and software requirements. ESP32 board pins' will next be comprehended. You will also learn how to download and install the required software components. The circuit schematic and ESP32 coding will also be explained in detail. Further, you will understand the Blynk App download and setup, authentication token code and WiFi settings.

Following that, the ESP32 board will be explained in a step-by-step manner. First, you will discover general details about the board, specifications, programming environments and preparing the ESP board in Arduino IDE. Next, you will learn how to load your first code to the ESP Board. Then, the final sections will cover coding LED Blink, touch sensors, dealing with analogue signals, PWM signals and servo motor control using PWM signal in ESP32.
