Enjoy Circuits, a unique word game with daily challenges!

Place and wire electronic components (even a lemon) to create a virtual circuit from scratch, or use our starter circuits to explore and try things out. No additional hardware required.

Build real electronic circuits in your browser. Start from zero and follow our step-by-step guides — each one explains what's happening and why, with a live interactive simulation right there on the page.

Build and navigate your circuits there. If Voltmeters and Ammeters are out of the toolbox, you can take measurements. In Control Area: Voltmeters and Ammeters can be found in the Sensor Toolbox. …

An electronic circuit can usually be categorized as an analog circuit, a digital circuit, or a mixed-signal circuit (a combination of analog circuits and digital circuits).

Electric circuits are classified in several ways. A direct-current circuit carries current that flows only in one direction. An alternating-current circuit carries current that pulsates back and forth many times …
