With Examples for Raspberry Pi Pico and ESP32 Creating and programming small electronic systems is now easier than ever before. With inexpensive development boards and modern software tools, anyone curious about embedded design can quickly move from an idea to a working piece of hardware. At the heart of this change is MicroPython—a clear, interactive, and beginner-friendly way to program microcontrollers while still remaining closely connected to the underlying electronics. This book introduces embedded programming through MicroPython on popular platforms such as the Raspberry Pi Pico and the ESP32. You will discover how to use microcontrollers for reading inputs, processing data, and controlling outputs in a predictable, real-time loop. With just a few lines of code, you can blink LEDs, read sensors, drive motors, and communicate with the outside world. The interactive REPL programming interface encourages experimentation and fast learning, making concepts tangible from the very first chapter. While different boards offer different capabilities, they all share the same core principles. Timers, GPIO, analog I/O, PWM, interrupts, and communication interfaces form the foundation of every embedded system. By focusing on these universal building blocks, this book helps you build skills that transfer across platforms and scale naturally toward more advanced development. Whether you are a beginner or an experienced programmer entering embedded systems, you will find that working with MicroPython is both practical and genuinely enjoyable.

Ready to explore the world around you? By attaching the Sense HAT to your Raspberry Pi, you can quickly and easily develop a variety of creative applications, useful experiments, and exciting games. The Sense HAT contains several helpful environmental sensors: temperature, humidity, pressure, accelerometer, magnetometer, and gyroscope. Additionally, an 8x8 LED matrix is provided with RGB LEDs, which can be used to display multi-color scrolling or fixed information, such as the sensor data. Use the small onboard joystick for games or applications that require user input. In Innovate with Sense HAT for Raspberry Pi, Dr. Dogan Ibrahim explains how to use the Sense HAT in Raspberry Pi Zero W-based projects. Using simple terms, he details how to incorporate the Sense HAT board in interesting visual and sensor-based projects. You can complete all the projects with other Raspberry Pi models without any modifications. Exploring with Sense HAT for Raspberry Pi includes projects featuring external hardware components in addition to the Sense HAT board. You will learn to connect the Sense HAT board to the Raspberry Pi using jumper wires so that some of the GPIO ports are free to be interfaced to external components, such as to buzzers, relays, LEDs, LCDs, motors, and other sensors. The book includes full program listings and detailed project descriptions. Complete circuit diagrams of the projects using external components are given where necessary. All the projects were developed using the latest version of the Python 3 programming language. You can easily download projects from the book’s web page. Let’s start exploring with Sense HAT.

Multitasking and multiprocessing have become a very important topic in microcontroller-based systems, namely in complex commercial, domestic, and industrial automation applications. As the complexity of projects grows, more functionalities are demanded from the projects. Such projects require the use of multiple inter-related tasks running on the same system and sharing the available resources, such as the CPU, memory, and input-output ports. As a result of this, the importance of multitasking operations in microcontroller-based applications has grown steadily over the last few years. Many complex automation projects now make use of some form of a multitasking kernel. This book is project-based and its main aim is to teach the basic features of multitasking using the Python 3 programming language on Raspberry Pi. Many fully tested projects are provided in the book using the multitasking modules of Python. Each project is described fully and in detail. Complete program listings are given for each project. Readers should be able to use the projects as they are, or modify them to suit their own needs. The following Python multitasking modules have been described and used in the projects: Fork Thread Threading Subprocess Multiprocessing The book includes simple multitasking projects such as independently controlling multiple LEDs, to more complex multitasking projects such as on/off temperature control, traffic lights control, 2-digit, and 4-digit 7-segment LED event counter, reaction timer, stepper motor control, keypad based projects, car park controller, and many more. The fundamental multitasking concepts such as process synchronization, process communication, and memory sharing techniques have been described in projects concerning event flags, queues, semaphores, values, and so on.
