This book is a practical guide to digital electronics, covering the essential components of modern digital systems: number systems, logic gates, Boolean algebra, combinational and sequential logic, and more.

Through more than 20 structured projects, you’ll design and build digital systems using real-world components such as logic gates, multiplexers, decoders, flip-flops, counters, and shift registers. The projects range from basic LED logic circuits to digital locks, display systems, traffic light controllers, and timing-based designs.

Selected projects introduce the use of tools such as CircuitVerse for circuit simulation, while several designs make use of 74HC-series logic devices, commonly used in digital hardware prototyping.

Inside, you’ll find:

• Clear coverage of number systems and binary arithmetic
• Logic gate fundamentals and universal gate implementations
• Step-by-step projects using flip-flops, counters, and registers
• Real-world design with 74HC-series logic chips
• Techniques for designing combinational and sequential systems

This book takes a design-first, application-driven approach to digital electronics—built around working circuits, tested logic, and hands-on experimentation.
