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.
This bundle contains the popular Elektor Sand Clock for Raspberry Pi Pico and the new Elektor Laser Head Upgrade, offering even more options for displaying the time. Not only can you "engrave" the current time in sand, you can now alternatively write it on a glow-in-the-dark foil or create green drawings.
Contents of the bundle
Elektor Sand Clock for Raspberry Pi Pico (normal price: €50)
NEW: Elektor Laser Head Upgrade for Sand Clock (normal price: €35)
Elektor Sand Clock for Raspberry Pi (Raspberry Pi-based Eye Catcher)
A standard sand clock just shows how time passes. In contrast, this Raspberry Pi Pico-controlled sand clock shows the exact time by "engraving" the four digits for hour and minute into the layer of sand. After an adjustable time the sand is flattened out by two vibration motors and everything begins all over again.
At the heart of the sand clock are two servo motors driving a writing pen through a pantograph mechanism. A third servo motor lifts the pen up and down. The sand container is equipped with two vibration motors to flatten the sand. The electronic part of the sand clock consists of a Raspberry Pi Pico and an RTC/driver board with a real-time clock, plus driver circuits for the servo motors.
A detailed construction manual is available for downloading.

Elektor Laser Head Upgrade for Sand Clock
The new Elektor Laser Head transforms the Sand Clock into a clock that writes the time on glow-in-the-dark film instead of sand. In addition to displaying the time, it can also be used to create ephemeral drawings. The 5 mW laser pointer, with a wavelength of 405 nm, produces bright green drawings on the glow-in-the-dark film. For best results, use the kit in a dimly lit room. Warning: Never look directly into the laser beam!
The kit includes all the necessary components, but soldering three wires is required.
Note: This kit is also compatible with the original Arduino-based Sand Clock from 2017. For more details, see Elektor Magazine 1-2/2017 and Elektor Magazine 1-2/2018.
The DiP-Pi PIoT is an Advanced Powered, WiFi connectivity System with sensors embedded interfaces that cover most of possible needs for IoT application based on Raspberry Pi Pico. It can supply the system with up to 1.5 A @ 4.8 V delivered from 6-18 VDC on various powering schemes like Cars, Industrial plant etc., additionally to original micro-USB of the Raspberry Pi Pico.

Both A/D inputs are bridged with 0402 resistors (0 OHM) therefore if for any reason user needs to use those Pico pins for their own application can be easy removed. The charger is automatically charging connected battery (if used) but in addition user can switch charger ON/OFF if their application needs it.
DiP-Pi PIoT can be used for cable powered IoT systems, but also for pure Battery Powered System with ON/OFF. Each powering source status is indicated by separate informative LEDs (VBUS, VSYS, VEPR, CHGR, V3V3).
User can use any capacity of LiPo or Li-Ion type; however, must take care to use PCB protected batteries with max discharge current allowed of 2 A. The embedded battery charger is set to charge battery with 240 mA current. This current is set by resistor so if user need more/less can himself to change it. The DiP-Pi PIoT is also equipped with WiFi ESP8266 Clone module with embedded antenna. This feature open a wide range of IoT applications based on it.
In Addition to all above features DiP-Pi PIoT is equipped with embedded 1-wire, DHT11/22 sensors, and micro–SD Card interfaces.

The Raspberry Pi Debug Probe is an all-in-one USB-to-debug kit that provides all the necessary hardware and cables for easy, solderless, plug-and-play debugging.
It features both a processor serial debug interface (by default the ARM Serial Wire Debug interface, but other interfaces can be supported) and an industry-standard UART interface. Both interfaces use the Raspberry Pi 3-pin debug connector.
It is designed to make it easy to debug and program Raspberry Pi Pico and RP2040 with a range of host platforms including Windows, Mac, and typical Linux computers.
While designed for use with Raspberry Pi products, the Debug Probe provides standard UART and CMSIS-DAP interfaces over USB, so it can also be used with other processors, or even just as a USB-to-UART cable. It works with OpenOCD and other tools that support CMSIS-DAP.
The Debug Probe is based on Raspberry Pi Pico hardware and runs the open source Raspberry Pi Pico Probe software. The firmware is updated in the same way as Raspberry Pi Pico firmware, so it is easy to keep the unit up to date with the latest firmware, or to use custom firmware.
