Electronics and Coding with Raspberry Pi
Stop just reading about circuits and start building them. Learn to control the physical world with code, from blinking your first light to designing smart home gadgets.
Like Duolingo, but for Electronics and Coding with Raspberry Pi. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
175 levels across 8 sections, about 350 minutes end to end, roughly 70 days at five minutes a day. It moves through Your First Win: Lighting Up the World, Taking Control with Code, Sensing the Environment, Making Things Move, Displays and Visual Feedback, Connecting to the Internet, Designing Professional Circuits, and The Deep Science: Why It Works. It starts from scratch.

Key ideas in Electronics and Coding with Raspberry Pi
- A circuit requires a power source, a load (LED), and a conductive path (wires)
- LEDs are directional (polarized)
- Electricity cannot jump through air to complete a circuit
- Physical markers like leg length and flat edges indicate orientation
- Electricity only flows in a complete, unbroken loop
- Electricity requires a potential difference (push) between two points
- Distinguish between the physical indicators of LED polarity
- A break anywhere in the loop stops flow everywhere in that path
- The negative terminal provides the return path to complete the loop
- Electricity leaves the positive terminal
- Electricity passes through the component and returns to the negative terminal
- A closed circuit has no gaps in the conductive path
- A switch in the 'off' position creates an open circuit
- Voltage is the force that drives electrical flow
- Identify the three essential components of a functional circuit
- Batteries are rated by their voltage output
You've tried the other tabs
Thirty open tabs. Four facts you actually kept.
You watched. You nodded. By Sunday it was gone.
One answer, then back to scrolling.
Eight weeks. You meant to finish. You didn't.
Tomo gives Electronics and Coding with Raspberry Pi the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
Here's what playing it feels like
A real question from this course. Take your best guess.
