This course is ideal for everyone who wishes to effortlessly upgrade the software version of an IoT project without the need for cables or complex protocols. We teach you how to program and update your ESP32 board with the help of the Over the Air (OTA) technique. You'll learn how to configure a wireless access point and create a web server that allows you to upload wirelessly your new firmware to your microcontroller.Initially we investigate OTA updating and its potential to transform any project including an ESP32 into an Over the Air enabled one. After that you'll discover the necessary libraries and how to install them in the Arduino IDE. Then we investigate an OTA's basic example and the procedure of uploading your code over the air to your ESP board. The code changes required to enable OTA updates on each project you are working on are also outlined.Finally you will study how to construct an internet-connected electronic project utilising a WiFi breakout board. Then we investigate the software and hardware needed for our project and the capabilities peripherals and GPIO pins of the ESP32 board. Following that we explain how to download and install Arduino IDE ESP and USB drivers. Lastly we explore the loading of your first code to the ESP32 board using an example sketch and the LED Blink programming. Enrol now and take a step towards the future of Internet of Things advancement!
