An Introduction To Digital Electronics

This course is meant to create a pathway into learning about digital electronics (hardware), for people who are scared of the math and general trickery that usually comes with it. A hands-on approach is taken in this course through a combination of lecture and experimentation to teach you about the different basic ideas (number systems, boolean algebra and logic gates) used in digital electronics.

Lectures
  1. The Introduction

    Lesson 1: The Introduction

    If you have never studied digital electronics before and want to get started broadening your knowledge of all things digital, then you have come to the right place. This first lesson explains what this course is about, what tools you’ll need to follow along with the course and what expectations you should have from taking this course.

    • Number Systems

      Lesson 2: Number Systems

      The first step in the digital world is getting to know number systems. Specifically, in this lesson we will look more closely at the binary and decimal number systems. Understanding binary and how it works is crucial to understanding digital logic because everything in the digital world is either a 0 or 1, or if you prefer, true or false.

      • Logic Gates

        Lesson 3: Logic Gates

        The fundamental representation of digital hardware comes in a symbol form, called logic gates. These gates perform boolean algebra in a visual way that leads to what are called logic diagrams. In this lesson, we’ll learn the basic logic gates of digital electronics and experiment with them to make sure they do what they should.

        • Kmaps

          Lesson 4: Kmaps

          Moving beyond number systems and logic gates, we have boolean equations and karnaugh maps. In this lesson we will learn two methods for simplifying logic circuits using boolean equations and kmaps and then we will implement the circuits to verify our math. This lesson is a tough one, so get your brain ready to be jammed full with information.

          • SR Latch

            Lesson 5: Design an SR Latch

            The next step into the digital work is to create stable logic elements. The first such element is called a latch and it can be built using simple logic gates. In this lesson we will explore how to build a latch using NOR logic gates and NAND logic gates. In addition, we will take a look at what timing diagrams are and how to use them.

            • Flip Flops

              Lesson 6: Flip Flops

              To take another gigantic step into the world of digital electronics, we need to learn about flip-flops. In this lesson we take a look at two types of the flip-flops, the JK and D flip-flops. To learn what they are and how they work, we will put them in some experimental circuits and see how they react. Additionally, we will start to learn about digital clock signals.

              • Clocks and Oscillators

                Lesson 7: Clocks and Oscillators

                To take another gigantic step into the world of digital electronics, we need to learn about flip-flops. In this lesson we take a look at two types of the flip-flops, the JK and D flip-flops. To learn what they are and how they work, we will put them in some experimental circuits and see how they react. Additionally, we will start to learn about digital clock signals.

                • Design A 4-Bit Shift Register

                  Lesson 8: Design A 4-Bit Shift Register

                  With all the basics covered, we can start to combine digital logic elements together and make useful devices. In this lesson we will take some flip-flops and other logic elements to build a 4-bit shift register. Some LEDs will be used to show you exactly how the shift register works.

                  • Design A 4-Bit Counter

                    Lesson 9: Design A 4-Bit Counter

                    A great strength of digital circuitry is that the clock can act as a timer or counter with appropriate flip-flop circuitry in place. In this lesson, using some LEDs, we will learn how to build a 4-bit binary counter that uses the clock input to tell our circuit to increment a counter with every clock period.

                    • Design an LED Chaser

                      Lesson 10: Design an LED Chaser

                      Electronics is not all about theory all the time, some moments do come when you get to have some fun. In this lesson we are going to celebrate our wealth of knowledge and just go design something fun. An LED chaser is loosely defined as a system where LEDs follow one another in a certain pattern, so start go start designing!

                      • 7400 Series Logic Devices

                        Lesson 11: 7400 Series Logic Devices

                        After you have mastered the digital fundamentals you are ready to grow and move to the more complex areas that exist. This bonus lesson dives into the more advanced 7400 logic IC’s available to us as designers and looks specifically at 3 interesting IC’s. The experiment for this lesson is to build a knight rider LED circuit.

                        • 4000 Series Logic Devices

                          Lesson 12: 4000 Series Logic Devices

                          After you have mastered the digital fundamentals you are ready to grow and move to the more complex areas that exist. This bonus lesson dives into the more advanced 4000 logic IC’s available to us as designers and looks specifically at 3 interesting IC’s. The experiment for this lesson is to build a 4-bit single IC counter.

                          Say Thank You To Our Kickstarter Backers For This Course!

                          Generally, electronics is a difficult subject mathematically, however theoretically it's actually not as bad if you take a hands-on approach and create vivid imagery to demonstrate what is going on. Using this approach, virtually anyone with a basic math background and a desire to know more about electronics can get started. So the following prerequisites are necessary for this course:

                          Syllabus

                          Overview

                          This Introduction To Digital Electronics course will be split up into 12 lessons with the lecture video for each lesson hosted on youtube. The lectures will be to 10-16 minutes in length so that you have enough time to see the information and can go over it twice to perform any of the experiments while following along with the video. Each lecture will contain 4 main sections, an introduction, a plain english explanation, theory and real world example. In addition, each lesson video will be hosted at PyroEDU with downloadable offline information and material like homework, schematics, formulas and parts information.

                          Expectations

                          This course is meant to take you, the learner, from a blank slate to a more informed individual by teaching about digital hardware in a hands-on way, as the lecture videos will emphasize and guide you with experimentation. You should expect to learn the basic concepts used in the digital domain like number systems, logic gates, boolean algebra and kmaps. Beyond that, you should also expect to get a better 'feeling' for what it takes to make an all-digital-hardware design.

                          Teacher qualifications

                          Hello! Aside from building many electronics tutorials and projects, and posting their full hardware schematics and source code on PyroElectro.com, I studied computer and electrical engineering at university and have Bachelor's + Master's degrees in the subject. My work is typically more slanted to digital hardware, however the basics are the same no matter if you're an analog designer or a digital designer.

                          Sensors Course - How To Sense Sound Lesson (2015-06-04 21:39:20)

                          "Hello Students!

                          Time to use some sound sensors in our new PyroEDU Introduction to Sensors course. This is a lesson about interfacing with sound sensors, here's a quick overview of this lesson:

                          We all hear and use sound in our daily lives, so we must also learn how to detect sound electronically. In this lesson we will use an electret microphone to convert sound from an acoustic wave, into an electrical signal.
