Practical Python programming for IoT : build advanced IoT projects using a Raspberry Pi 4 MQTT RESTful APIs WebSockets and Python 3 The age of connected devices is here be it fitness bands or smart homes. Its now more important than ever to understand how hardware components interact with the internet to collect and analyze user data. The Internet of Things (IoT) combined with the popular open source language Python can be used to build powerful and intelligent IoT systems with intuitive interfaces. This book consists of three parts with the first focusing on the internet component of IoT. Youll get to grips with end to end IoT app development to control an LED over the internet before learning how to build RESTful APIs WebSocket APIs and MQTT services in Python. The second part delves into the fundamentals behind electronics and GPIO interfacing. As you progress to the last part youll focus on the Things aspect of IoT where you will learn how to connect and control a range of electronic sensors and actuators using Python. Youll als explore a variety of topics such as motor control ultrasonic sensors and temperature measurement. Finally youll get up to speed with advanced IoT programming techniques in Python integrate with IoT visualization and automation platforms and build a comprehensive IoT project. By the end of this book youll be well versed with IoT development and have the knowledge you need to build sophisticated IoT systems using Python
