A Fast-Lane Ride From Concept to Project
The core of the book explains the use of the Raspberry Pi Zero 2 W running the Python programming language, always in simple terms and backed by many tested and working example projects. On part of the reader, familiarity with the Python programming language and some experience with one of the Raspberry Pi computers will prove helpful. Although previous electronics experience is not required, some knowledge of basic electronics is beneficial, especially when venturing out to modify the projects for your own applications.
Over 30 tested and working hardware-based projects are given in the book, covering the use of Wi-Fi, communication with smartphones and with a Raspberry Pi Pico W computer. Additionally, there are Bluetooth projects including elementary communication with smartphones and with the popular Arduino Uno. Both Wi-Fi and Bluetooth are key features of the Raspberry Pi Zero 2 W.
Some of the topics covered in the book are:
Raspberry Pi OS installation on an SD card
Python program creation and execution on the Raspberry Pi Zero 2 W
Software-only examples of Python running on the Raspberry Pi Zero 2 W
Hardware-based projects including LCD and Sense HAT interfacing
UDP and TCP Wi-Fi based projects for smartphone communication
UDP-based project for Raspberry Pi Pico W communication
Flask-based webserver project
Cloud storage of captured temperature, humidity, and pressure data
TFT projects
Node-RED projects
Interfacing to Alexa
MQTT projects
Bluetooth-based projects for smartphone and Arduino Uno communications
Learn to program displays and GUIs with Python
This book is about Raspberry Pi 4 display projects. The book starts by explaining how to install the latest Raspbian operating system on an SD card, and how to configure and use the GPIO ports.
The core of the book explains the following topics in simple terms with fully tested and working example projects:
Simple LED projects
Bar graph LED projects
Matrix LED projects
Bitmap LED projects
LED strips
LCDs
OLED displays
E-paper displays
TFT displays
7-inch touch screen
GUI Programming with Tkinder
One unique feature of this book is that it covers almost all types of display that readers will need to use in their Raspberry Pi based projects. The operation of each project is fully given, including block diagrams, circuit diagrams, and commented full program listings. It is therefore an easy task to convert the given projects to run on other popular platforms, such as Arduino or PIC microcontrollers.
Python program listings of all Raspberry Pi projects developed in this book are available for download at Elektor.com. Readers can use these programs in their projects. Alternatively, they can modify the programs to suit their applications.
The Picon Zero is an add-on for the Raspberry Pi. It has the same size as a Raspberry Pi Zero, making it ideal to function as a pHat. Of course, it can be used on any other Raspberry Pi via a 40-pin GPIO connector.
As well as two full H-Bridge motor drivers, the Picon Zero has several Input/Output pins giving you multiple configuration options. That allows you to easily add outputs or analog inputs to your Raspberry Pi without any complicated software or kernel-specific drivers. At the same time, it opens up 5 GPIO pins from the Raspberry Pi, and it provides the interface for an HC-SR04 ultrasonic distance sensor.
The Picon Zero comes with all components, including the headers and screw terminals, fully soldered. Soldering isn't required. You can use it right out of the box.
Features
pHat format PCB: 65 mm x 30 mm
Two full H-Bridge motor drivers. Drive up to 1.5 A continuously per channel, at 3 V - 11 V.
Each motor output has both a 2-pin male header and a 2-pin screw terminal.
The motors can be powered from the Picon Zero's 5 V or an external power source (3 V - 11 V).
The Picon Zero's 5 V can be selected to be from the Raspberry Pi's 5 V line, or a USB connector on the Picon Zero. That means that you can effectively have 2 USB battery banks: one to power the servos and motors on the Picon Zero and the other to power the Pi.
4 Inputs that can accept up to 5 V. These inputs can be configured as follows:
Digital inputs
Analog inputs
DS18B20
DHT11
6 Outputs that can drive 5 V and be configured as:
Digital Output
PWM Output
Servo
NeoPixel WS2812
All Inputs and Outputs use GVS 3-pin male headers.
4-pin female header that connects directly to an HC-SR04 ultrasonic distance sensor.
8-pin female header for Ground, 3.3 V, 5 V, and 5 GPIO signals allowing you to add their additional features.
Raspberry Pi 5 provides two four-lane MIPI connectors, each of which can support either a camera or a display. These connectors use the same 22-way, 0.5 mm-pitch “mini” FPC format as the Compute Module Development Kit, and require adapter cables to connect to the 15-way, 1 mm-pitch “standard” format connectors on current Raspbery Pi camera and display products.These mini-to-standard adapter cables for cameras and displays (note that a camera cable should not be used with a display, and vice versa) are available in 200 mm, 300 mm and 500 mm lengths.
Build robust, intelligent machines that combine Raspberry Pi computing power with LEGO components.
The Raspberry Pi Build HAT provides four connectors for LEGO Technic motors and sensors from the SPIKE Portfolio. The available sensors include a distance sensor, a color sensor, and a versatile force sensor. The angular motors come in a range of sizes and include integrated encoders that can be queried to find their position.
The Build HAT fits all Raspberry Pi computers with a 40-pin GPIO header, including – with the addition of a ribbon cable or other extension device — Raspberry Pi 400. Connected LEGO Technic devices can easily be controlled in Python, alongside standard Raspberry Pi accessories such as a camera module.
Features
Controls up to 4 motors and sensors
Powers the Raspberry Pi (when used with a suitable external PSU)
Easy to use from Python on the Raspberry Pi
