The eBook is helpful in building electronic projects, study and verify the results, and learn basic electronic circuits.

This eBook guides you to build an electronics project ‘Build Switch and Logic Gates Using Transistors on the Breadboard’ using NPN Transistors 2N2222A.

To implement the realization of each ‘logic gate’, you combine two or more NPN transistor switch circuits.

Logic gates are semiconductor devices, and we use them as the building block of any digital device.

A logic gate has two or more inputs and one output, and on the input, we supply digital signals and on the output; it provides processed digital output.

Topics covered are building a transistor switch and two input NOT (INVERTER), AND, NAND, OR, NOR, and XOR logic gates using NPN transistors.

I illustrate the ‘NPN transistor switch’ and each ‘logic gate’ with a schematic diagram and an explanation.

To verify the truth table of each logic gate practically, I provide a breadboard wiring diagram for each circuit.

This book is useful for engineers, technicians, students, and hobbyists who want to conduct experiments, and it is affordable too.

The project in the eBook explains all the relevant topics in a simple and descriptive manner for you.

Building these electronic projects rapidly boosts your skills and analytic power to a great level. We have used it in thousands of applications and is extremely popular.
