Using the RFID Starter Kit An Arduino board has now become ‘the’ basic component in the maker community. No longer is an introduction to the world of microcontrollers the preserve of the expert. When it comes to expanding the capabilities of the basic Arduino board however, the developer is still largely on his own. If you really want to build some innovative projects it’s often necessary to get down to component level. This can present many beginners with major problems. That is exactly where this book begins. This book explains how a wide variety of practical projects can be built using items supplied in a single kit together with the Arduino board. This kit, called the 'RFID Starter Kit for Arduino' (SKU 17240) is not just limited to RFID applications but contains more than 30 components, devices and modules covering all areas of modern electronics. In addition to more simple components such as LEDs and resistors there are also complex and sophisticated modules that employ the latest technology such as: A humidity sensor A multicolor LED A large LED matrix with 64 points of light A 4-character 7-segment LED display An infra red remote-controller unit A complete LC-display module A servo A stepper motor and controller module A complete RFID reader module and security tag On top of that you will get to build precise digital thermometers, hygrometers, exposure meters and various alarm systems. There are also practical devices and applications such as a fully automatic rain sensor, a sound-controlled remote control system, a multifunctional weather station and so much more. All of the projects described can be built using the components supplied in the Elektor kit.

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.

De Arduino Nano is een klein, compleet en breadboard-vriendelijk bordje gebaseerd op de ATmega328 (Arduino Nano 3.x). Het heeft min of meer dezelfde functionaliteit als de Arduino Duemilanove, maar in een andere verpakking. Het mist alleen een DC voedingsaansluiting en werkt met een Mini-B USB-kabel in plaats van een standaard kabel. Specificaties Microcontroller ATmega328 Bedrijfsspanning (logisch niveau) 5 V Ingangsspanning (aanbevolen) 7-12 V Inputspanning (limieten) 6-20 V Digitale I/O-pinnen 14 (waarvan 6 met PWM-uitgang) Analoge ingangspinnen 8 DC-Stroom per I/O-Pin 40 mA Flashgeheugen 16 KB (ATmega168) of 32 KB (ATmega328) waarvan 2 KB gebruikt door bootloader SRAM 1 KB (ATmega168) of 2 KB (ATmega328) EEPROM 512 bytes (ATmega168) of 1 KB (ATmega328) Kloksnelheid 16 MHz Afmetingen 18 x 45 mm Voeding De Arduino Nano kan via de Mini-B USB-verbinding, 6-20 V ongeregelde externe voeding (speld 30), of 5 V geregelde externe voeding (speld 27) worden aangedreven. De voedingsbron wordt automatisch geselecteerd op de hoogste spanningsbron. Geheugen De ATmega168 heeft 16 KB flash-geheugen voor het opslaan van code (waarvan 2 KB wordt gebruikt voor de bootloader), 1 KB SRAM en 512 bytes EEPROM De ATmega328 heeft 32 KB flash-geheugen voor de opslag van code, (waarvan ook 2 KB wordt gebruikt voor de bootloader), 2 KB SRAM en 1 KB EEPROM. Input en output Elk van de 14 digitale pinnen op de Nano kan worden gebruikt als ingang of uitgang, met behulp van pinMode(), digitalWrite(), en digitalRead() functies. Zij werken bij 5 V. Elke pin kan maximaal 40 mA leveren of ontvangen en heeft een interne pull-up weerstand (standaard uitgeschakeld) van 20-50 kOhms. Communicatie De Arduino Nano heeft een aantal faciliteiten om te communiceren met een computer, een andere Arduino, of andere microcontrollers. De ATmega168 en ATmega328 bieden UART TTL (5V) seriële communicatie, die beschikbaar is op de digitale pennen 0 (RX) en 1 (TX). Een FTDI FT232RL op de raad kanaliseert deze periodieke mededeling over USB en de FTDI drivers (inbegrepen met de Arduino-software) verstrekt een virtuele com-haven aan software op de computer. De Arduino-software omvat een seriële monitor waarmee eenvoudige tekstuele gegevens naar en van de Arduino-raad kunnen worden verzonden. De RX en TX LEDs op het bord zullen knipperen wanneer gegevens via de FTDI-chip en de USB-verbinding met de computer worden verzonden (maar niet voor seriële communicatie op pennen 0 en 1). Een SoftwareSerial bibliotheek maakt seriële communicatie op elk van de digitale pinnen van de Nano mogelijk. Programmeren De Arduino Nano kan geprogrammeerd worden met de Arduino software (download). De ATmega168 of ATmega328 op de Arduino Nano wordt geleverd met een bootloader waarmee u nieuwe code kunt uploaden zonder het gebruik van een externe hardware programmeur. Het communiceert met behulp van het originele STK500 protocol (referentie, C header files). U kunt ook de bootloader omzeilen en de microcontroller programmeren via de ICSP (In-Circuit Serial Programming) header met Arduino ISP of vergelijkbaar; zie deze instructies voor details. Automatisch (software) resetten Rather dan het vereisen van een fysieke druk van de het terugstellenknoop vóór een upload, wordt Arduino Nano ontworpen op een manier die het om door software toelaat worden teruggesteld die op een verbonden computer loopt. Eén van de hardwarestroom controlelijnen (DTR) van deFT232RL wordt verbonden met de het terugstellenlijn van de ATmega168 of ATmega328 via een 100 nF condensator. Wanneer deze lijn wordt bevestigd (laag genomen), daalt de resetlijn lang genoeg om de chip te resetten. De Arduino-software gebruikt dit vermogen om u toe te staan om code te uploaden door eenvoudig de uploadknoop in het Arduino-milieu te drukken. Dit betekent dat de bootloader een kortere time-out kan hebben, aangezien het verlagen van DTR goed gecoördineerd kan worden met het begin van de upload.
