Elektor Digital Home Automation and Electronics for Starters (E-book)
Projects with Arduino, ESPHome, Home Assistant, and Raspberry Pi & Co. We start by learning about electrical engineering by looking at the basics of voltage and current and the types of resistors, diodes and transistors. In the second chapter, we get to know the most famous microcontroller, the Arduino Uno. We will analyze its structure, learn how to code and carry out illustrative examples. In chapter three, we set up Home Assistant on a Raspberry Pi. We look at scenes, automations and the general handling of HA. We then look at the MQTT protocol, which is the gold standard in home electronics communication, so to speak, but other interfaces such as I²C, SPI and UART are also explained in detail in this chapter. In the following chapter we will take a look at the ESP8266, the more modern ESP32 and of course the ESP32-CAM. First some theory, followed by practical examples. Indoor climate sensors for temperature and humidity, motion sensors, RFID readers and many more sensors are explained in detail in chapter 7, followed by practical examples. Chapter 8 deals with actuators such as the 7-segment display, servo motors, displays, stepper motors and much more. You can use ESPHome to integrate sensors and actuators into Home Assistant without any programming effort. In this chapter, you will be guided step by step through how to integrate your own sensors. Do you want to bring more colorful light into your living space? Then the chapter on LEDs is just right for you. The different types of LED lights are explained here and, of course, the basics of lighting technology are not forgotten. There are a lot of ICs in electronics that make our lives easier; in this chapter we get to know a few ICs and the basic knowledge is immediately put into practice. All code examples do not have to be typed out, you can download them for free from GitHub and modify them. The respective link (with QR code) can be found in the code example.

Soldered Soldered Inkplate 6COLOR (with E-paper)
Inkplate 6COLOR continues the tradition of the well-known, user-friendly Inkplate series which is compatible with Arduino and Micropython. Inkplate 6COLOR offers a unique innovation – the ability to display colors on the screen. Inkplate 6COLOR has a 5.85" folded e-paper that displays a total of 7 different colors (Black, White, Red, Yellow, Blue, Green, and Orange). Considering the built-in dithering capability, the results you can get on the screen are really impressive. Powered by ESP32, you will have strong microcontroller with WiFi and Bluetooth on your disposal. It’s super-low-power (18 uA) so you can use it for days, weeks, or months out of a single battery charge. Using our Arduino library (100% compatible with Adafruit GFX), it’s 5 minute work to get the board running for you. The Micropython module is available as well. It’s 100% open-source for both software and hardware. What is especially interesting is that Inkplate uses recycled screens taken from old e-book readers, which is very environmentally friendly, but you have to keep in mind that some screens may have small scratches because of this. All screens with large scratches and damages are not used at all. Features 5.85-inch, 600x448 pixel electronic paper with the ability to display 7 different colors Powered by an ESP32 microcontroller with built-in WiFi and Bluetooth 4.0 (BLE) Consumes extremely small amount of power, whether powered by a lithium battery or USB, in deep sleep mode it consumes only 18 µA, so it will run on one battery for years, and there is also a battery charger located on the board! MicroSD card reader from which Inkplate 6COLOR can extract images to display on its display Additional GPIO lines available, easyC/Qwiic compatibility and I²C and SPI support Arduino library ready (100% compatible with Adafruit GFX) and micropython that enable display of text, images and geometric shapes Dimensions: 131.5 x 105.5 x 10 mm Downloads Arduino library Inkplate documentation Getting started with Inkplate

Elektor Digital Controller Area Network Projects (E-BOOK)
The Controller Area Network (CAN) was originally developed to be used as a vehicle data bus system in passenger cars. Today, CAN controllers are available from over 20 manufacturers, and CAN is finding applications in other fields, such as medical, aerospace, process control, automation, and so on. This e-book (pdf) is written for students, for practising engineers, for hobbyists, and for everyone else who may be interested to learn more about the CAN bus and its applications. The aim of this e-book is to teach you the basic principles of CAN networks and in addition the development of microcontroller based projects using the CAN bus. In summary, this e-book enables the reader to: Learn the theory of the CAN bus used in automotive industry Learn the principles, operation, and programming of microcontrollers Design complete microcontroller based projects using the C language Develop complete real CAN bus projects using microcontrollers Learn the principles of OBD systems used to debug vehicle electronics You will learn how to design microcontroller based CAN bus nodes, build a CAN bus, develop high-level programs, and then exchange data in real-time over the bus. You will also learn how to build microcontroller hardware and interface it to LEDs, LCDs, and A/D converters. The e-book assumes that the reader has some knowledge on basic electronics. Knowledge of the C programming language will be useful in later chapters of the e-book, and familiarity with at least one member of the PIC series of microcontrollers will be an advantage, especially if the reader intends to develop microcontroller based projects using the CAN bus.
