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 projectsSimple LED projectsBar graph LED projectsMatrix LED projectsBitmap LED projectsLED stripsLCDsOLED displaysE-paper displaysTFT displays7-inch touch screenGUI Programming with TkinderOne 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.
