39 Experiments with Raspberry Pi and Arduino This book is about Raspberry Pi 3 and Arduino camera projects. The book explains in simple terms and with tested and working example projects, how to configure and use a Raspberry Pi camera and USB based webcam in camera-based projects using a Raspberry Pi. Example projects are given to capture images, create timelapse photography, record video, use the camera and Raspberry Pi in security and surveillance applications, post images to Twitter, record wildlife, stream live video to YouTube, use a night camera, send pictures to smartphones, face and eye detection, colour and shape recognition, number plate recognition, barcode recognition and many more. Installation and use of popular image processing libraries and software including OpenCV, SimpleCV, and OpenALPR are explained in detail using a Raspberry Pi. The book also explains in detail how to use a camera on an Arduino development board to capture images and then save them on a microSD card. All projects given in this book have been fully tested and are working. Program listings for all Raspberry Pi and Arduino projects used in this book are available for download on the Elektor website.

Learn to interface and program hardware devices in a wide range of useful applications, using ARM7 microcontrollers and the C programming language. Examples covered in full detail include a simple LED to a multi-megabyte SD card running the FAT file system. Features of this book Build prototype circuits on breadboard or Veroboard and interface to ARM microcontrollers. A 32-bit ARM7 microcontroller is used in interfacing and software examples. Interfacing principles apply to other ARM microcontrollers and other non-ARM microcontrollers as well. Example programs are written in the C programming language. Use only free or open source software. Download and install all programming tools from the Internet. Template project files are provided for easy project creation. Hardware Interface to LEDs, transistors, optocouplers, relays, solenoids, switches, keypads, LCD displays, seven segment displays, DC motors, stepper motors, external analogue signals using the ADC, RS232, RS-485, TWI, USB, SPI and SD memory cards. Software Once hardware has been interfaced to a microcontroller, software must be written to control the hardware. You will learn how to write programs to operate externally interfaced hardware devices, use timers and interrupts. Also learn how to port FAT file system code for use with an SD memory card, program the PWM to produce an audio sine wave, program the PWM to speed control a DC motor and more. A chapter on more advanced ARM microcontrollers is included with an overview of some of the newest ARM microcontrollers and their features.

35 projecten met Raspberry Pi en wireless Arduino Internet of Things (alles aan het internet) is een trend die zich niet meer laat keren. We willen alles in huis met onze mobiel of tablet doen, van Facebook tot TV kijken, van lichten bedienen tot de temperatuur in de gaten houden. In dit boek laten we in 35 leuke en handige projecten zien hoe u op eenvoudige wijze zelf een Internet of Things systeem kunt aanleggen. We gaan in op de hardware (de perfecte combinatie van Raspberry Pi en Arduino) en de software om bediening via internet mogelijk te maken. We maken gebruik van Wi-Fi en radioverbindingen zodat er geen kabels dwars door uw huis hoeven. Wanneer u deze projecten maakt heeft u een compleet Internet of Things systeem waarmee u van alles in uw huis kunt bedienen en bekijken. Bijvoorbeeld of er post in de brievenbus ligt en of de auto in de garage staat. U kunt op vanaf de bank het licht aandoen en het alarm bedienen. Door de heldere uitleg kunt u de projecten eenvoudig aanpassen om bijvoorbeeld uw koffiezetautomaat of tv op afstand aan te zetten. Via de index vindt u gemakkelijk creatieve projecten die als voorbeeld kunnen dienen, zodat u zelfstandig alles met het internet kunt verbinden.
