When I published my first book “Home Automation with Raspberry©, Google© and Python©: an useful and fun Home Automation project”, www.amazon.com, both in Spanish and English, I received several comments from readers encouraging me to write another book for beginners in the use of micro controllers such as the Raspberry©, Arduino© or ESP32© as a basis for the creation of small projects development exercises, which will be explained step by step, more slowly, in more detail, more easily, etc. how to use an ESP32©, starting from scratch and adding elements from less to more complexity: LED, buttons, sensors, sounds, switches, controllers, Home Automation devices, access from the Web, voice control, IFTTT©, server Web, etc.
