Learn electronics from the circuit up
Circuits, components, and the ideas that make electronics work
Electronics Fundamentals is the home for practical, platform-independent electronics at The Makers Workbench. Start with core electrical principles, learn how components and integrated circuits behave, and continue through power, sensors, construction, and test equipment.
Circuit FundamentalsBuild a strong foundation in voltage, current, resistance, circuit laws, signals, feedback, schematics, and circuit analysis.Components & SemiconductorsExplore the passive components and semiconductor devices that make electronic circuits work.Analog & Digital ElectronicsUnderstand analog signal processing, digital logic, converters, timers, and the integrated circuits used to build complete systems.Power & ControlLearn how electronic systems generate, regulate, protect, switch, and convert power—and how they control motors and other loads.Sensors & InterfacesExplore the sensors, displays, controls, and communication interfaces that connect circuits to people and the physical world.Microcontrollers & CommsLearn how microcontrollers work inside, and how they talk to each other and to the world through UART, I²C, SPI, USB, and wireless links.Building & TestingMove from schematic to working hardware with practical guidance on assembly, PCB design, test equipment, measurement, and troubleshooting.
