The FLIRC Raspberry Pi Zero Case is compatible with Raspberry Pi Zero W and the newer Raspberry Pi Zero 2 W.
The design of the FLIRC Zero Case is based on the original FLIRC case. As with the original, the aluminum housing serves as protection and, thanks to the contact point on the processor, as a passive cooler. Ideal for silent operation.
In addition to a normal cover that encloses and protects the Raspberry Pi Zero, there is a second cover that allows access to the GPIO pins through a small opening.
The Cytron Maker Pi Pico (with Raspberry Pi Pico RP2040 soldered on Board) incorporates the most wanted features for your Raspberry Pi Pico and gives you access to all GPIO pins on two 20 ways pin-headers, with clear labels. Each GPIO is coupled with an LED indicator for convenient code testing and troubleshooting. The bottom layer of this board even comes with a comprehensive pinout diagram showing the function of each pin. Features Work out-of-the-box. No soldering!

The default configuration holds a mini breadboard (included), an SD card adapter, 2x micro SD cards, 2x USB devices, a micro-USB shim and of course the Raspberry Pi Zero itself.
Users can decide to use the micro-USB shim slot to hold a micro-HDMI adapter, or you may want to hold a Portsplus or similar GPIO reference card in the SD adapter slot. You can choose to store your USB micro-SD card reader or even other larger USB devices such as the USBDoctor. Use it in whatever way works best for you.
All of the Raspberry Pi Zero ports are accessible from the ZeroDock, including the camera port and reset/composite pin header. pHATs are also not obstructed, so you’re free to prototype with your favourite add-on boards.
The case is a stylish mix of clear and black acrylic layers, black fixings and a clear breadboard, fitting in well alongside most desktop PCs/monitors.

Multitasking and multiprocessing have become a very important topic in microcontroller-based systems, namely in complex commercial, domestic, and industrial automation applications. As the complexity of projects grows, more functionalities are demanded from the projects. Such projects require the use of multiple inter-related tasks running on the same system and sharing the available resources, such as the CPU, memory, and input-output ports. As a result of this, the importance of multitasking operations in microcontroller-based applications has grown steadily over the last few years. Many complex automation projects now make use of some form of a multitasking kernel.
This book is project-based and its main aim is to teach the basic features of multitasking using the Python 3 programming language on Raspberry Pi. Many fully tested projects are provided in the book using the multitasking modules of Python. Each project is described fully and in detail. Complete program listings are given for each project. Readers should be able to use the projects as they are, or modify them to suit their own needs.
The following Python multitasking modules have been described and used in the projects:
Fork
Thread
Threading
Subprocess
Multiprocessing
The book includes simple multitasking projects such as independently controlling multiple LEDs, to more complex multitasking projects such as on/off temperature control, traffic lights control, 2-digit, and 4-digit 7-segment LED event counter, reaction timer, stepper motor control, keypad based projects, car park controller, and many more. The fundamental multitasking concepts such as process synchronization, process communication, and memory sharing techniques have been described in projects concerning event flags, queues, semaphores, values, and so on.
