Preface

An LED is a simple actuator device that displays lighting and can be controlled easily using Raspberry Pi. This book will explain processes to control LEDs using Raspberry Pi—from describing ideas to designing and implementing several projects based on LEDs, such as 7-segment, 4-digit 7-segment, and dot matrix displays. Samples of the project application are provided, such as a countdown timer, a digital clock, a traffic light controller, a remote light controller, and an LED-based Internet of Things, to get more practice with the Raspberry Pi development.

Raspberry Pi LED Blueprints is an essential reference for practical solutions to build the LED-based application. Beginning with step-by-step instructions for installation and configuration, this book can either be read from cover to cover or treated as an essential reference companion to your Raspberry Pi.

I hope that you will find this book useful and it will help you take your skills to a higher level.
