This DIY Color Display Kit is a fun and educational project for makers of all ages. It is a great way to learn about electronics, programming, and improve your soldering skills. Microcontroller As this kit ships with the ePulse Feather ESP32 development board, the kit thereby inherits all the great features of said devkit. Display The large 3.5" 320x480 color display also sports a high-precision capacitive touch interface. Contrary to resistive touch interfaces that often work best when using a stylus this auto-calibrated module offers a smartphone-like user experience. Connector PCB The connectors for the display are already pre-assembled on the connector PCB, as those require a more experienced hand at the soldering iron. Hence, for the inexperienced solderer this offers the best of both worlds. Also, you may choose to not add the on-off switch or the Grove connector; both are optional. The connector PCB offers extendability in two ways: the broken out pins of the microcontroller and the connector for the Grove system.

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 newcomer to Microchip’s PIC microcontrollers invariably gets an LED to flash as their first attempt to master this technology. You can use just a simple LED indicator in order to show that your initial attempt is working, which will give you confidence to move forward. This is how the book begins — simple programs to flash LEDs, and eventually by stages to use other display indicators such as the 7-segment display, alphanumeric liquid crystal displays and eventually a colour graphic LCD. As the reader progresses through the book, bigger and upgraded PIC chips are introduced, with full circuit diagrams and source code, both in assembler and C. In addition, a small tutorial is included using the MPLAB programming environment, together with the EAGLE schematic and PCB design package to enable readers to create their own designs using the book’s many case studies as working examples to work from.
