Course Description

Are you an Arduino maker, able to 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 have realized that while these platforms are great for helping you to start tinkering with electronics, you will not be able to truly enjoy their power until you have understood basic electronics.
This is what this course is about. It is about helping you achieve a better level of understanding of the basic electronics principles and components that are commonly used in making on platforms like the Arduino and the 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, LED, 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.Who this course is for:
  • Anyone with minimal experience using an Arduino
  • Anyone with minimal experience using any prototyping platform
  • Anyone with a need to brush up their knowledge of basic electronics

The course has everything one needs to get STARTED for building circuits using Arduino. I personally never had confidence in making small circuits and have had forgotten everything that I learned in the past. I have already done my MS and to revise my basics, I would recommend watching this course. However, if you're an EE/CE Engineer, you should refer to other materials along with these lectures in parallel as it is too basic.

2nd question on that resistor quiz with 2 power supplies had me very confused, but besides that, I learned a lot.

excellent !!!!!. super good explanation . easy to followi learned a lot from this course .

Very complete and didactic course, thank you so much.

The course wasn't as basic as I truly needed. I feel more time could be spent on what a specific item is and its use or purpose before we in to seeing how to input the component int o a circuit. Overall I did learn new things so it s worth the time.

This is a fantastic course for beginning in electronics and also as a refresher for anyone who is already experienced. Peter does an awesome job. I highly recommend Tech Explorations courses.

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.

Peter is great at sharing his knowledge in an enjoyable and easy to understand way.

Good balance of theory and application. My 8th grader loves it!

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.

Thanks so much for putting out this course material that was clear and relevant. Looking forward to moving on to more advanced courses with you.

I learned the basics of electronics and how to work the connections on an Arduino breadboard
