Two reasons can be identified for the immense success of the Arduino platform. First, the cheap, ready to go processor board greatly simplifies the introduction to hardware. The second success factor is the free and open-source programming suite that does not require an installation procedure. Simple entry-level examples ensure rapid successes. Complex selection procedures for parameters like the microprocessor version or interface settings are not required. The first sample programs can be uploaded to the Arduino board, and tested, in a matter of minutes. The Arduino user is supported by an array of software libraries. However, the daily increasing volume of libraries poses initial problems to the newcomer, and the way ahead may be uncertain after a few entry-level examples. In many cases, detailed descriptions are missing, and poorly described projects tend to confuse rather than elucidate. Clear guidance and a single motto are missing, usually owing to the projects having been created by several different persons—all with different aims in mind. This book represents a different approach. All projects are presented in a systematical manner, guiding into various theme areas. In the coverage of must-know theory great attention is given to practical directions users can absorb, including essential programming techniques like A/D conversion, timers and interrupts—all contained in the hands-on projects. In this way readers of the book create running lights, a wakeup light, fully functional voltmeters, precision digital thermometers, clocks of many varieties, reaction speed meters, or mouse controlled robotic arms. While actively working on these projects the reader gets to truly comprehend and master the basics of the underlying controller technology.

Recently, the development of a tiny chip called the ESP8266 has made it possible to interface any type of microcontroller to a Wi-Fi AP. The ESP8266 is a low-cost tiny Wi-Fi chip having fully built-in TCP/IP stack and a 32-bit microcontroller unit. This chip, produced by Shanghai based Chinese manufacturer Espressif System, is IEEE 802.11 b/g/n Wi-Fi compatible with on-chip program and data memory, and general purpose input-output ports. Several manufacturers have incorporated the ESP8266 chip in their hardware products (e.g. ESP-xx, NodeMCU etc) and offer these products as a means of connecting a microcontroller system such as the Android, PIC microcontroller or others to a Wi-Fi. The ESP8266 is a low-power chip and costs only a few Dollars. ESP8266 and MicroPython – Coding Cool Stuff is an introduction to the ESP8266 chip and describes the features of this chip and shows how various firmware and programming languages such as the MicroPython can be uploaded to the chip. The main aim of the book is to teach the readers how to use the MicroPython programming language on ESP8266 based hardware, especially on the NodeMCU. Several interesting and useful projects are given in the e-book (pdf) to show how to use the MicroPython in NodeMCU type ESP8266 hardware: Project “What shall I wear today?”: You will be developing a weather information system using a NodeMCU development board together with a Text-to-Speech processor module. Project “The Temperature and Humidity on the Cloud”: You will be developing a system that will get the ambient temperature and humidity using a sensor and then store this data on the cloud so that it can be accessed from anywhere. Project “Remote Web Based Control”: You will be developing a system that will remotely control two LEDs connected to a NodeMCU development board using an HTTP Web Server application.

Atmel AVR ist eine 8-bit-Mikrocontroller-Familie des Herstellers Atmel. Diese Controller sind wegen ihres einfachen Aufbaus, ihrer leichten Programmierbarkeit, den kostenlosen Entwicklungswerkzeugen und der Verfügbarkeit in DIP-Gehäuseformen auch bei Elektronikern und Makern äußerst beliebt. Darüber hinaus sind diese Controller bereits ab zwei Euro erhältlich. Im Arduino Uno-Board wird der ATmega328 verwendet. AVR-Programmierung für Quereinsteiger besteht aus zwei Teilen. Im ersten Teil wird in einfachen Worten erklärt, wie eine MCU (= Micro Controller Unit) im Detail arbeitet. Dem folgt eine Einführung in die Programmiersprache C. Anschließend taucht der Leser im zweiten Teil des Buches in die Welt der Register und ihre Bits ein. Dort findet man auch ein umfangreiches Glossar aller Register- und Bit-Namen. Das Buch dient somit auch als Nachschlagewerk, wenn man sich durch das Datenblatt oder andere Texte arbeiten muss. Das Buch wendet sich an alle, die bisher mit dem Arduino programmiert haben und nun nach technischen Möglichkeiten und Wegen suchen, ihre Elektronik- und Programmierkenntnisse zu erweitern. Dazu eignet sich die AVR-Programmierung im besonderen Maße.

If you enjoy DIY electronics, projects, software and robots, you’ll find this book intellectually stimulating and immediately useful. With the right parts and a little guidance, you can build robot systems that suit your needs more than overpriced commercial systems can. 20 years ago, robots based on simple 8-bit processors and touch sensors were the norm. Now, it’s possible to build multi-core robots that can react to their surroundings with intelligence. Today’s robots combine sensor readings from accelerometers, gyroscopes and computer vision sensors to learn about their environments. They can respond using sophisticated control algorithms and they can process data both locally and in the cloud. This book, which covers the theory and best practices associated with advanced robot technologies, was written to help roboticists, whether amateur hobbyist or professional, take their designs to the next level. As will be seen, building advanced applications does not require extremely costly robot technology. All that is needed is simply the knowledge of which technologies are out there and how best to use each of them. Each chapter in this book will introduce one of these different technologies and discuss how best to use it in a robotics application. On the hardware side, we’ll cover microcontrollers, servos, and sensors, hopefully inspiring you to design your own awe-inspiring, next-generation systems. On the software side, we’ll cover programming languages, debugging, algorithms, and state machines. We’ll focus on the Arduino, the Parallax Propeller, Revolution Education PICAXE and projects I’ve with which I’ve been involved, including the TBot educational robot, the PropScope oscilloscope, the 12Blocks visual programming language, and the ViewPort development environment. In addition, we’ll serve up a comprehensive introduction to a variety of essential topics, including output (e.g. LEDs, servo motors), and communication technologies (e.g. infrared, audio), that you can use to develop systems that interact to stimuli and communicate with humans and other robots. To make these topics as accessible as possible, handy schematics, sample code and practical tips regarding building and debugging have been included. Hanno Sander Christchurch, New Zealand
