Steek een lezer in de headers, gebruik een Qwiic kabel, scan je 125kHz ID tag, en het unieke 32-bit ID wordt op het scherm getoond. De unit wordt geleverd met een lees LED en buzzer, maar maak je geen zorgen, er is een jumper die je kunt doorknippen om de buzzer uit te schakelen als je dat wilt. Door gebruik te maken van SparkFun's handige Qwiic systeem, is er geen soldeerwerk nodig om het aan te sluiten op de rest van je systeem. We hebben echter nog steeds 0.1'-spaced pinnen als u liever een breadboard gebruikt. Met behulp van de ATtiny84A aan boord, neemt de Qwiic RFID de zes bytes ID tag van je 125kHz RFID kaart, koppelt er een tijdstempel aan, en zet het op een stapel die tot 20 unieke RFID scans per keer kan bevatten. Deze informatie is gemakkelijk te verkrijgen met enkele eenvoudige I²C commando's.
De Arduino Pro Mini is een microcontroller board gebaseerd op de ATmega328P.
Het heeft 14 digitale in-/uitgangspinnen (waarvan er 6 kunnen worden gebruikt als PWM-uitgangen), 6 analoge ingangen, een on-board resonator, een reset-knop, en gaten voor het monteren van pin headers. Een six-pin header kan worden aangesloten op een FTDI-kabel of Sparkfun breakout board om USB-voeding en communicatie te bieden aan de board.
De Arduino Pro Mini is bedoeld voor semi-permanente installatie in voorwerpen of tentoonstellingen. Het board komt zonder pre-gemonteerde headers, waardoor het gebruik van diverse types van schakelaars of het directe solderen van draden is toegestaan. De pin lay-out is compatibel met Arduino Mini.

Functionality, structure and handling of a power module
For readers with first steps in power management the “Abc of Power Modules” contains the basic principles necessary for the selection and use of a power module. The book describes the technical relationships and parameters related to power modules and the basis for calculation and measurement techniques.
Contents
Basics
This chapter describes the need of a DC/DC voltage converter and its basic functionality. Furthermore, various possibilities for realizing a voltage regulator are presented and the essential advantages of a power module are mentioned.
Circuit topologies
Circuit concepts, buck and boost topologies very frequently used with power modules are explained in detail and further circuit topologies are introduced.
Technology, construction and regulation technology
The mechanical construction of a power module is presented, which has a significant influence on EMC and thermal performance. Furthermore, control methods are explained and circuit design tips are provided in this chapter.
Measuring methods
Meaningful measurement results are absolutely necessary to assess a power module. The relevant measurement points and measurement methods are described in this chapter.
Handling
The aspects of storage and handling of power modules are explained, as well as their manufacturing and soldering processes.
Selection of a power modules
Important parameters and criteria for the optimal selection of a power module are presented in this section.
Most people are increasingly confronted with the applications of Artificial Intelligence (AI). Music or video ratings, navigation systems, shopping advice, etc. are based on methods that can be attributed to this field.
The term Artificial Intelligence was coined in 1956 at an international conference known as the Dartmouth Summer Research Project. One basic approach was to model the functioning of the human brain and to construct advanced computer systems based on this. Soon it should be clear how the human mind works. Transferring it to a machine was considered only a small step. This notion proved to be a bit too optimistic. Nevertheless, the progress of modern AI, or rather its subspecialty called Machine Learning (ML), can no longer be denied.
In this book, several different systems will be used to get to know the methods of machine learning in more detail. In addition to the PC, both the Raspberry Pi and the Maixduino will demonstrate their capabilities in the individual projects. In addition to applications such as object and facial recognition, practical systems such as bottle detectors, person counters, or a “talking eye” will also be created.
The latter is capable of acoustically describing objects or faces that are detected automatically. For example, if a vehicle is in the field of view of the connected camera, the information 'I see a car!' is output via electronically generated speech. Such devices are highly interesting examples of how, for example, blind or severely visually impaired people can also benefit from AI systems.

Programming the Finite State Machine with 8-Bit PICs in Assembly and C
Andrew Pratt provides a detailed introduction to programming PIC microcontrollers, as well as a thorough overview of the Finite State Machine (FSM) approach to programming. Most of the book uses assembly programming, but do not be deterred. The FSM gives a structure to a program, making it easy to plan, write, and modify. The last two chapters introduce programming in C, so you can make a direct comparison between the two techniques. The book references the relevant parts of the Microchip datasheet as familiarity with it is the best way to discover detailed information.
This book is aimed at Microsoft Windows and Linux users. To keep your costs to a minimum and to simplify the toolchain, specific applications are provided as a free download to enable you to use an FTDI serial lead as the programmer. The assembler used is the open-source "gpasm". All programming can be done in a text editor. There are detailed instructions on how to perform the necessary installations on Windows, Linux Debian, and derivatives such as Ubuntu and Fedora. For programming in C, Microchip's XC8 compiler is used from the command line. In addition to the programming applications, two serial read and serial write applications can be used for communicating with the PICs from a computer.
A voltmeter project including practical instructions on building a circuit board from scratch is included. All theory is covered beforehand, including how to do integer arithmetic in assembly.
Two PICs are covered: the PIC12F1822 and the PIC16F1823. Both can run at 32 MHz with an internal oscillator. You do not need to buy a factory-made development board and programmer. With relatively inexpensive parts including a serial lead, microcontroller, a few resistors, and LEDs, you can get started exploring embedded programming.
