This book is about teaching the Python programming language using the Raspberry Pi 4 computer. The book makes an introduction to Raspberry Pi 4 and then teaches Python with the topics: variables, strings, arrays, matrices, tuples, lists, dictionaries, user functions, flow of control, printing, keyboard input, graphics, GUI, object oriented programming and many more topics. The book is aimed for beginners, students, practising engineers, hobbyists, and for anyone else who may want to learn to program in Python. The book includes many example programs and case studies. All the example programs and case studies have been tested fully by the author and are all working. The example programs aim to teach the various programming concepts of Python. The case studies cover the use of Python in the analysis and design of electronic circuits. Some of the case study topics are: Resistor colour code identification Resistive potential divider circuits Resistive attenuator design Zener diode voltage regulator design RC and RLC transient circuits Circuit frequency response Saving data on external memory stick Mesh and node circuit analysis using matrices Resonance in RLC circuits Transistor Biasing analysis Transistor amplifier design Design of active filters Interfacing hardware with GPIO, I²C and SPI Using Wi-Fi with Python and TCP/IP and UDP programs Using Bluetooth from Python Full program listings of all the programs used in the book are available at the Elektor website of the book. Readers should be able just to copy and use these programs in their Raspberry Pi projects without any modifications.

Unlike other Raspberry Pi boards, the Raspberry Pi Pico does not have a built-in video output. However, thanks to programmable IO (PIO) and this Pico DVI Sock, it is possible to add a DVI video output to the Raspberry Pi Pico! The Pico DVI Sock was developed by Luke Wren, a Raspberry Pi engineer, in his spare time. He has published the design online under a CC0 license, so everybody can build the hardware from his provided files. The physical video interface of the Pico DVI Sock is an HDMI connector, but it outputs a DVI signal. Historically, HDMI is a successor to DVI – so DVI signals can be simply transmitted using HDMI. Simple passive adapters allow you to connect HDMI cables to a DVI port. The DVI Sock can be soldered to one end of the Raspberry Pi Pico. Thanks to the castellated edges of the Pico, soldering is very easy. Let your creativity run wild with an additional digital video output on the Pico. Here are some suggestions / possible project ideas: Mini game console based on the Raspberry Pi Pico Output of measurement values on a monitor

This anodised aluminium heatsink case will protect your Raspberry Pi 4 and give you very effective passive cooling. It's great in cases where you want completely silent cooling, for instance, if you're building a home media center. The scope of delivery includes a thermal pad to provide thermal contact between the CPU and top case, and a handy Allen key and set of hex bolts to attach the case together. The case gives you access to all of the ports, pins, and connectors. Features Anodised aluminium top and bottom case Heatsink fins Thermal pad Hex bolts and Allen key included Access to all ports, pins, and connectors Compatible with Raspberry Pi 4 Assembly Assembling your heatsink case is pretty easy and should only take a couple of minutes. The first, and most important thing is to make sure that your Pi is powered off and unplugged before you fit the case. Take one of the thermal pads and peel the protective films off both sides of it (there's a white film and an easy-to-miss clear film on the other side. Stick the thermal pad onto your Pi's CPU (the metal square nearest the middle of the PCB). Sticking the thermal pad to the CPU first is a much better way to position it correctly than trying to stick it to the case. Only use one thermal pad with the Raspberry Pi 4. Position the top case and then, holding it in place, flip the whole thing over and position the bottom case on the underside of your Pi. Use the four hex bolts and allen key to secure the case. Notes The case is metal and hence conductive, so be careful not to short any components on it, and ensure that your RPi is powered off and unplugged when fitting the case It may be obvious, but the case will get hot in use Dimensions: 87 × 56 × 25.5 mm

It is possible to control Cytron 25Amp 7-58 V High Voltage DC Motor Driver with PWM and DIR inputs. The input logic voltage ranges from 1.8 V to 30 V and the board is compatible with variety of host controllers (such as Arduino, Raspberry Pi, PLC). If you don't want to deal with programming to control the motor, there is an option to control the motor driver from a potentiometer (speed) and a switch (direction). You can also test the motor quickly and conveniently using the onboard test buttons and motor output LEDs without the need to hook up the host controller. It is possible to power the host controller with the buck regulator which produces 5 V output. This is especially useful for high voltage applications where no additional power source nor high voltage buck regulator is needed. This motor driver also incorporates various protection features. If the motor stalls or you've hooked up an oversized motor, the overcurrent protection will take care of the board and protect it from damage. If the motor is trying to draw current more than what the motor driver can support, the motor current will be limited at the maximum threshold. Assisted by temperature protection, the maximum current limiting threshold depends on the board temperature. The higher the board temperature, the lower the current limiting threshold. Note: Power input does not have reverse-voltage protection. Connecting the battery in reverse polarity will damage the motor driver instantaneously. Features Bidirectional control for one brushed DC motor Operating Voltage: DC 7 V to 58 V Maximum Motor Current: 25 A continuous, 60 A peak 5 V output for the host controller (250 mA max) Buttons for quick testing LEDs for motor output state Dual Input Mode: PWM/DIR or Potentiometer/Switch Input PWM/DIR Inputs compatible with 1.8 V, 3.3 V, 5 V, 12 V and 24 V logic (Arduino, Raspberry Pi, PLC, etc) PWM frequency up to 40 kHz (Output frequency is fixed at 16 kHz) Overcurrent protection with active current limiting Temperature protection Undervoltage shutdown Scope of delivery 1 × MD25HV (motor driver board) 1 × Potentiometer with connector 1 × Rocker switch with connector 4 × Nylon PCB Standoffs/Spacers Documents Datasheet Sample Code
