How this platform works
Every lesson is one of three phases:
| Phase | What you do |
|---|---|
| Phase | What you do |
| Concept | Read and understand (like this lesson) |
| Explore | Experiment freely with a virtual circuit |
| Practice | Complete guided exercises step by step |
You'll start with concepts, then explore, then practice. Let's begin with the most important question:
What exactly is a microcontroller?
