Basic electronics for Arduino Makers (Udemy.com)

An introduction to electronics to help you make the most from your Arduino or other prototyping platform.

Created by: Dr. Peter Dalmaris

Last updated August 2024

Our take

Based on the ratings of 2,145 students, a sample of their written reviews and the syllabus, as the course stood in August 2024. No course pays to be reviewed.

This is the odd one out among the Arduino courses we list. It isn't about programming an Arduino at all. Dr. Peter Dalmaris teaches the electronics that sit around the board: voltage, current, Ohm's Law, Kirchhoff's Laws, then a section each on resistors, capacitors, diodes, transistors and voltage regulators. It runs about 10 hours over 66 lectures with 15 quizzes, and it was last updated in August 2024; the course description says newer lectures cover an online circuit simulator. It's aimed at people who already build small Arduino circuits from guides and want to know why the parts are there.

Reviewers consistently praise the teaching. They like his pace and clarity, non-native English speakers say they follow him without trouble, and one student went from barely knowing what a battery was to being able to walk into a parts store and ask for what he needs. The complaints are practical. One student burned LEDs and a capacitor because he couldn't see which breadboard holes Dalmaris was using and wanted a screenshot. Others wanted a proper lesson on using a multimeter, felt the variable voltage regulator section was confusing, or found some resistor quizzes didn't match the lecture before them. One 4-star reviewer bought the whole parts list and felt much of it went unused.

At 4.7 from more than 2,100 reviews, with 90 percent giving 4 or 5 stars, the course is well liked and the criticisms are mild. It sits beside Arduino Step by Step: Getting Started in our Arduino list, and one French reviewer says that course is his next stop after this one. If you are happy following wiring diagrams and never wondering why, skip it. If you want to design your own circuits, this is the more useful 10 hours.

Best forArduino tinkerers who can copy a sketch but can't explain why a base resistor or a pull-up is in the circuit.
Skip it ifYou've never touched an Arduino, or you want Arduino programming rather than the electronics underneath it.

Pros

  • Clear delivery at a pace non-native English speakers say they can follow
  • Covers the parts Arduino guides skip over: transistor base resistors, pull-ups, RC filters, zener diodes
  • Last updated August 2024, with added lectures on an online circuit simulator
  • Hands-on breadboard builds and 15 quizzes rather than pure theory

Cons

  • Breadboard shots can be hard to follow; one student fried LEDs guessing which holes he used
  • No dedicated lesson on using a multimeter, which the parts list asks you to buy
  • Some students found parts on the shopping list barely used and the regulator section confusing
Peter does a great job at presenting the material in a way you can understand. I have enjoyed this course and learned quite a bit while brushing up quite a bit as well.
Elvis Barbee, a student

Beginner in electronics, not in Arduino: you should have wired a few small circuits from guides and know basic algebra.

Course Description

I have updated this course with new lectures to teach you how to use an online circuit simulator. With this simulator, you can boost your understanding and learning of electronics. You will be able to conduct many experiments to examine multiple circuit scenarios and easily plot currents, voltages, and power without hardware expense. You will learn to use multiple power sources and built-in and custom component models. You can even conduct experiments that would be too dangerous to do in real life.

-

Are you an Arduino maker? Can you make things by following how-to guides and are confident with writing or modifying sketches? Yet you are not so confident about things like calculating transistor currents, voltage drops, and using capacitors as filters?

You are not alone. I have been teaching Arduino and Raspberry Pi topics for years. During this time, I realized that while these platforms are great for helping you start tinkering with electronics, you will not be able to enjoy their power until you truly understand basic electronics.

This course is about helping you achieve a better understanding of the basic electronics principles and components commonly used in making platforms like Arduino and Raspberry Pi.

I have designed this course for anyone with a basic understanding of electronics who has already spent time tinkering with Arduinos. 

By the end of this course, you will have learned how to use commonly used components found in Arduino projects. You will also have learned how to do the relevant measurements and calculations to help you select appropriate components for your projects. 

To complete this course, you will need a few cheap and common components and tools: resistors, capacitors, transistors, LEDs, diodes, and batteries. You will also need a multimeter, a small breadboard, and jumper wires. All of these are probably things that you already have.

Je suis très satisfait de ce cours sur les bases de l'électronique pour Makers. L'instructeur enseigne de façon progressive et très intéressante et les exercices sont là pour mettre de la pratique en suivant le cours dédié. La pratique sur plaque d'essai est aussi intéressante dans chaque élément étudié. Les vidéos sont très nettes, les vues sont parfaites, l'instructeur parle à un rythme aidant l'apprentissage (clic droit pour moi en traduisant en français), la documentation est complète. Je vais suivre le prochain cours sur les bases d'Arduino étape par étape. Un grand merci à Monsieur Dalmaris pour proposer des cours aussi qualitatifs qu'intéressant.

By Martin Enchev on 4/16/2020

It is a good course. Still I have some remarks regarding the way of solving the problems in Physics: at the beginning of every Physics book, there is a chapter about how many significant digits there are in the calculation, there is a way when to round up, when to round down, calculating with the Kirchhof's voltage principle needs usually more things to consider, like direction to walk through the the loop, assumption about the direction of the current in the parts of your loop, direction according the polarity of energy sources, I think, it would have been even better, if Professor Peter has also written the units (V, A, Ohm etc.) after the values. The last chapter is not quite helpful, as long as there is no explanation of what these voltage regulators actually are, are they transistors or diodes, for example. On the other hand, the explanations are concise and easy to understand, so it was interesting.

By Gabriel A. Cardenas on 9/25/2019

he is very clear about his explaining the description of the pieces (diodes, resisters, etc) and he talks at good pace tone. Only thing so far (40% thru) is the actual physical circuit setup isnt always clear and i have to do a little trial and error to get wires and resistors etc in the right places. Other thing that would be nice is maybe examples of where and why they are used in real circuits/electronics; that would have been really cool.

By Nathan Hepler on 5/9/2019

A lot of of good information is introduced here. This course is a good starting point, as it covers many important aspects of electronics. However, if you want to really learn the minute details behind most of the topics, you are going to have to look things up. That's not a bad thing because, in my opinion, this course works at the right kind of pace. You aren't bogged down in the details unless you choose to go digging.

By Marcos Andrade on 11/5/2018

Excellent course! I'm planning on joining the Arduino world, but I had really poor knowledge of electronics. So, before getting deep into the Arduino itself, I wanted to learn a bit more about electronics in general in order to fulfill this gap. During my search, I found this course which is basic electronics for Arduino. I didn't hesitate and bought it right away! Now, at the end of it, I can assure that every penny was worth it. I look forward to the next courses. The only issue I had so was that my math skills were a bit rusty, so I spent a little more time doing calculations than a recently graduated high school student. haha

Having worked as a Field Engineer for 45 years and being retired for 5 years it was great getting back the basics, the theoretical knowledge from 50 years ago when I started out. I am also enrolled in Dr. Peter Dalmaris's Arduino 2017 course and I am looking forward to applying much of what I have learned in this course! Dr. Dalmaris did an excellent job in teaching this course. I especially enjoyed his lectures. Mr. Gerald Goyette

I took this course as a software developer to broaden my knowledge of electronics. During my faculty days, long time ago, I found that I do get electrotechnics and electronics, but having your own electronics lab was expensive and software simulators were not yet available. This course was exactly what I needed: to refresh very basic Ohm's Law and kirchhoff's Laws and implement them in breadboard examples. Lots of pen and paper exercises as well as lots of hands on examples with real electrical current (yup, I burned couple of LE diodes :) ). Can't wait to see how can I apply all this in Arduino and actual coding as programming is my field of expertise.

By Anthony André Rey on 6/28/2017

Good course overall. Concepts between voltage and current are not explained clearly. For example, what a voltage drop is and why is there a voltage drop? What does it actually mean physically to have a voltage drop by a component in a circuit. These are concepts that I would have loved to know and understand prior to getting into more advanced concepts and formulas. Lesson 19. Give your values so that we may have an idea of which of (I)L or (I)T is bigger. For example, I get (I)T smaller than (I)L.. Lesson 21. Rt = 1/(1/R1 + 1/R2 + 1/R3) is not demonstrated.

By John McKenna on 5/6/2017

I am very happy so far, the only issue I have is with the parts ordering form and I am waiting for a clarification on that. my instructor was not able to resolve my parts ordering problem,so I worked around it by ordering directly from Amazon. com. Secondly I am still having a problem with a parallel resistor quiz and it's solution in lesson 14 and a parallel resistor problem in quiz 8. this because I don't fully under stand the solution in lesson 14. I have requested help from the instructor but he hasn't respond yet. Otherwise the course is going well.

By John Crisostomo on 11/25/2016

I decided to take this course first before going through the "Arduino: Step by Step" course by the same author, so that I can have a good grasp of the fundamentals. I have zero experience in electronics and I might say that this course is good, however, for someone who have zero knowledge in electronics (and haven't practiced Math in a while), the unit of measures can somehow get confusing because they weren't comprehensively explained and somehow used inconsistently throughout the examples. The quizzes are good, they are challenging in a good way, at least for me who have zero background in this field. :)
