No videos. On purpose.

This is a text-first course that links out to the best supporting material on the internet instead of trying to replace it. The goal is to make this the best course on circuit basics you can find — even without producing a single minute of custom video.

Hands-on from Day 1

Every day has a breadboard project. You build the circuits, not just read about them. A basic component kit is all you need.

Intuition before math

Ohm's Law makes sense once you feel what happens when resistance changes. This course builds physical intuition before introducing the equations.

Links to All About Circuits

All About Circuits is the canonical free electronics textbook. This course links to relevant chapters instead of rewriting them.

Completes in 5 one-hour sessions

Each day is designed to finish in about an hour of reading plus hands-on breadboard work. No live classes, no quizzes.

The 5 Days

Each day stands alone. Read them in order for the full picture, or jump straight to the day that answers the question you have today.

The best external videos on this topic.

Instead of shooting our own videos, we link to the best deep-dives already on YouTube. Watch them alongside the course. All external, all free, all from builders who ship this stuff.

Read the source.

The best way to go deeper on any topic is to read canonical open-source implementations. These repositories implement the core patterns covered in this course.

Three kinds of people read this.

Complete Beginners to Electronics

You've never built a circuit and want to understand how electronic hardware works. This course starts from the absolute beginning.

Software Developers Exploring Hardware

You write software and want to understand the hardware layer. Electronics fundamentals give you the intuition that makes embedded work click.

Arduino and Raspberry Pi Hobbyists

You've followed tutorials but don't fully understand why the circuits work. This course fills that gap.
