LoRaWAN has developed excellently as a communication solution in the IoT. The Things Network (TTN) has contributed to this. The Things Network was upgraded to The Things Stack Community Edition (TTS (CE)). The TTN V2 clusters were closed towards the end of 2021. This book shows you the necessary steps to operate LoRaWAN nodes using TTS (CE) and maybe extend the network of gateways with an own gateway. Meanwhile, there are even LoRaWAN gateways suitable for mobile use with which you can connect to the TTN server via your cell phone. The author presents several commercial LoRaWAN nodes and new, low-cost and battery-powered hardware for building autonomous LoRaWAN nodes. Registering LoRaWAN nodes and gateways in the TTS (CE), providing the collected data via MQTT and visualization via Node-RED, Cayenne, Thingspeak, and Datacake enable complex IoT projects and completely new applications at very low cost.

Bluetooth Low Energy (BLE) radio chips are ubiquitous from Raspberry Pi to light bulbs. BLE is an elaborate technology with a comprehensive specification, but the basics are quite accessible. A progressive and systematic approach will lead you far in mastering this wireless communication technique, which is essential for working in low power scenarios. This book shows you the ropes of BLE programming with Python and the Bleak library on a Raspberry Pi or PC, with C++ and NimBLE-Arduino on Espressif’s ESP32 development boards, and with C on one of the development boards supported by the Zephyr real-time operating system, such as Nordic Semiconductor's nRF52 boards.

This book is about Raspberry Pi 4 display projects. The book starts by explaining how to install the latest Raspbian operating system on an SD card, and how to configure and use the GPIO ports. This book is about Raspberry Pi 4 display projects. The book starts by explaining how to install the latest Raspbian operating system on an SD card, and how to configure and use GPIOs. The core of the book explains in simple terms and with tested and working example projects, how various types of display devices can be used in Raspberry Pi projects. Example projects provided use simple LEDs, bar graph LEDs, matrix LEDs, bit map LEDs, multi-digit 7-segment LEDs, LED strips, LCDs, OLEDs, E-paper displays, TFT displays, 7 inch touchscreen display modules, and many more. Tkinter is an inbuilt Python module used to create GUI applications. Tkinter is already part of Python and therefore there is no need to install it.

RISC-V is an Instruction Set Architecture (ISA) that is both free and open. This means that the RISC-V ISA itself does not require a licensing fee, although individual implementations may do so. The RISC-V ISA is curated by a non-profit foundation with no commercial interest in products or services that use it, and it is possible for anyone to submit contributions to the RISC-V specifications. The RISC-V ISA is suitable for applications ranging from embedded microcontrollers to supercomputers. This book will first describe the 32-bit RISC-V ISA, including both the base instruction set as well as the majority of the currently-defined extensions. The book will then describe, in detail, an open-source implementation of the ISA that is intended for embedded control applications. This implementation includes the base instruction set as well as a number of standard extensions.

The MSP430 is a popular family of microcontrollers from Texas Instruments. In this book we will work with the smallest type, which is the powerful MSP430G2553. We will look at the capabilities of this microcontroller in detail, as it is well-suited for self-made projects because it is available in a P-DIP20 package. We will take a closer look at the microcontroller and then build, step by step, some interesting applications, including a "Hello World" blinking LED and a nice clock application, which can calculate the day of the week based on the date. You also will learn how to create code for the MSP microcontroller in assembler. We will use the C-language to walk through our exercises and will not go down to the assembler level.
