Elektor Digital PIC Cookbook for Virtual Instrumentation (E-book)
The software simulation of gauges, control-knobs, meters and indicators which behave just like real hardware components on a PC’s screen is known as virtual instrumentation. In this book, the Delphi program is used to create these mimics and PIC based external sensors are connected via a USB/RS232 converter communication link to a PC. Detailed case studies in this Book include a virtual compass displayed on the PC’s screen, a virtual digital storage oscilloscope, virtual -50 to +125 degree C thermometer, and FFT sound analyser, a joystick mouse and many examples detailing virtual instrumentation Delphi components. Arizona’s embedded microcontrollers – the PIC's are used in the projects and include PIC16F84A, PIC16C71, DSPIC30F6012A, PIC16F877, PIC12F629 and the PIC16F887. Much use is made of Microchip’s 44 pin development board (a virtual instrument ‘engine)’, equipped with a PIC16F887 with an onboard potentiometer in conjunction with the PIC’s ADC to simulate the generation of a variable voltage from a sensor/transducer, a UART to enable PC RS232 communications and a bank of 8 LED's to monitor received data is also equipped with an ISP connector to which the ‘PICKIT 2’ programmer may easily be connected. Full source code examples are provided both for several different PIC’s, both in assembler and C, together with the Pascal code for the Delphi programs which use different 3rd party Delphi virtual components.

Elektor Digital Home Appliance Hack-and-IoT Guidebook (E-book)
Affordable solutions with the ESP8266 and 3D printing If you are looking for a small yet powerful IoT device, you are likely to come across the ESP8266 and compatible products on the market today. One of these, the Wemos/Lolin D1 Mini Pro board strikes a remarkable balance between cost and performance. A small and very affordable prototype board, the D1 Mini Pro stands out with its WiFi functionality and a 16-Mbytes flash memory for easy creation of a flash file system. In addition, there are sufficient input and output pins (only one analog input though) to support PWM, I²C, and One-Wire systems to mention but a few. The book describes the operation, modding, construction, and programming of home appliances including a colorful smart home accessory, a refrigerator/greenhouse controller, an AC powerline monitor, a door lock monitor, and an IKEA Trådfri controller. As a benefit, all firmware developed for these DIY, "IoT-ized" devices can be updated over-the-air (OTA). For most of the designs in the book, a small printed circuit board (PCB) and an enclosure are presented so readers can have a finished and attractive-looking product. Readers having – or with access to! – a 3D printer can "print" the suggested enclosures at home or in a shop. Some of the constructions benefit from a Raspberry Pi configured as a gateway or cms server. This is also described in detail with all the necessary configuring. You don’t need to be an expert but the prerequisites to successful replication of the projects include basic skills with PC software including the ability to surf the Internet. In terms of hardware, you should be comfortable with soldering and generally assembling the PCBs presented in the book. All custom software written for the IoT devices, the PCB layouts, and 3D print files described in the book are available for free downloading.
