Best alternatives to How Circuits Actually Work — for Programmers in 2026

If you've ever wired up an Arduino, flashed a microcontroller, or wondered what's actually happening inside a circuit board your code talks to, this is a free interactive course that walks you through electronics the way a programmer thinks — starting from voltage and current and building up to real embedded systems, without needing an electrical engineering degree. How Circuits Actually Work is a browser-based curriculum built specifically for software developers who want to close the gap between the code they write and the hardware it runs on. It's organized into five progressive acts — foundational linear circuits (Ohm's law, Kirchhoff's laws, resistors), non-linear components (diodes, transistors, op-amps), dynamic behavior (capacitors, inductors, timing), practical microcontroller integration (UART, I2C, SPI, power budgeting), and system-level design with six capstone projects. Exercises use an interactive Z3 constraint solver so learners can check their circuit math directly in the browser instead of just reading static diagrams. There's no visible pricing page or account system, and no clear company behind it — it reads as an independent educational resource rather than a SaaS product.
