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.

The Arduino Uno is an open-source microcontroller development system encompassing hardware, an Integrated Development Environment (IDE), and a vast number of libraries. It is supported by an enormous community of programmers, electronic engineers, enthusiasts, and academics. The libraries in particular really smooth Arduino programming and reduce programming time. What’s more, the libraries greatly facilitate testing your programs since most come fully tested and working. The Raspberry Pi 4 can be used in many applications such as audio and video media devices. It also works in industrial controllers, robotics, games, and in many domestic and commercial applications. The Raspberry Pi 4 also offers Wi-Fi and Bluetooth capability which makes it great for remote and Internet-based control and monitoring applications. This book is about using both the Raspberry Pi 4 and the Arduino Uno in PID-based automatic control applications. The book starts with basic theory of the control systems and feedback control. Working and tested projects are given for controlling real-life systems using PID controllers. The open-loop step time response, tuning the PID parameters, and the closed-loop time response of the developed systems are discussed together with the block diagrams, circuit diagrams, PID controller algorithms, and the full program listings for both the Raspberry Pi and the Arduino Uno. The projects given in the book aim to teach the theory and applications of PID controllers and can be modified easily as desired for other applications. The projects given for the Raspberry Pi 4 should work with all other models of Raspberry Pi family. The book covers the following topics: Open-loop and closed-loop control systems Analog and digital sensors Transfer functions and continuous-time systems First-order and second-order system time responses Discrete-time digital systems Continuous-time PID controllers Discrete-time PID controllers ON-OFF temperature control with Raspberry Pi and Arduino Uno PID-based temperature control with Raspberry Pi and Arduino Uno PID-based DC motor control with Raspberry Pi and Arduino Uno PID-based water level control with Raspberry Pi and Arduino Uno PID-based LED-LDR brightness control with Raspberry Pi and Arduino Uno

Aan de PC kant wordt gebruik gemaakt van de eveneens eenvoudig te leren gratis programmeertaal Small Basic van Microsoft. Deze taal is speciaal ontwikkeld om snel Windows programma's te kunnen ontwikkelen, ook voor mensen die weinig of geen PC programmeer ervaring hebben. U leert verschillende technieken om een PC met een microcontroller te laten communiceren zoals losse communicatie, het versterken en verzwakken van signalen, verwerken van valse metingen, master-slave communicatie en synchronisatie met geforceerde reset. Behalve theorie staan in het boek ook 15 leuke en praktische projecten. Door de duidelijke uitleg en instructies kunt u deze projecten zelf uitbreiden en helemaal aan uw eigen wensen aanpassen. Een paar voorbeelden uit het boek: Meet signalen en toon ze op de PC Maak een eigen muis of keyboard besturing. Meet en analyseer componenten (Spoel / Condensator / Transistor / OPAMP) met automatische grafieken op uw PC. Bestuur een servomotor vanaf de PC. Verzamel metingen in de Piccolino en zet ze later over naar uw PC. De combinatie van theorie en praktijkvoorbeelden in dit boek zorgt er voor dat u voor elk interface-probleem een oplossing bij de hand hebt, of weet hoe u er een moet maken.

Build Your Own Vintage Radio Broadcaster The Elektor AM Transmitter Kit allows streaming audio to vintage AM radio receivers. Based on a Raspberry Pi Pico microcontroller module, the AM Transmitter can transmit on 32 frequencies in the AM band, from 500 kHz up to 1.6 MHz in 32 steps of approx. 35 kHz. The frequency is selected with a potentiometer and shown on a 0.96" OLED display. A pushbutton allows toggles the transmitting mode between On and Off. The range of the transmitter depends on the antenna. The onboard antenna provides a range of a few centimeters, requiring the AM Transmitter to be placed close to or inside the radio. An external loop antenna (not included) can be connected to increase the range. The Elektor AM Transmitter Kit comes as a kit of parts that you must solder to the board yourself. Features The board is compatible with a Hammond 1593N enclosure (not included).A 5 VDC power supply with micro-USB connector (e.g., an old phone charger) is needed to power the kit (not included). Current consumption is 100 mA. The Arduino software (requiring Earle Philhower’s RP2040 Boards Package) for the Elektor AM Transmitter Kit plus more information is available at the Elektor Labs page of this project.

Die serielle Schnittstelle dient dem Datenaustausch zwischen Mikrocontrollern und Peripheriegeräten. Bei einer seriellen Datenübertragung werden die Bits nacheinander – also seriell – über eine Leitung übertragen. Das Wissen um diese seriellen Schnittstellen erweitert die Einsatzmöglichkeiten von Mikrocontrollern und Peripheriegeräten ungemein. In diesem Buch werden die Grundlagen der Kommunikation für die drei seriellen Schnittstellen I²C, SPI und 1-Wire vorgestellt. Anhand praxisnaher Beispiele werden die Schnittstellen anschaulich dargestellt und deren Einsatz verdeutlicht. Software- und Hardwarebeispiele, die man in diesem Buch finden kann, wurden in Assembler für PIC-Mikrocontroller von Microchip realisiert. Die verwendeten Algorithmen und Vorgehensweisen kann man aber auf beliebige Plattform übertragen. Um den Inhalt des Buches ansprechend zu gestalten, demonstriert der Autor den Buchinhalt an zwei Platinen. Mit diesen Platinen ist es möglich, die in diesem Buch beschriebenen Beispiele auszuprobieren und mit den Schnittstellen zu experimentieren. Beide Platinen basieren auf 8-bit-PIC-Mikrocontrollern von Microchip.
