de:volt is a breadboard simulator that runs real circuit physics in your browser. Wire up 105 parts on a 400 or 830-point board and the circuit runs as you build. Probe it with a 4-channel scope and multimeter, program an Arduino Uno or Nano, micro:bit or RP2040, learn with guided lessons that pass on real measurements, or run a whole class with assignments, marking and live lessons.

Could you build this?
Partial The breadboard UI and lessons are buildable, but accurate circuit physics for 105 parts plus cycle-accurate microcontroller emulation for Arduino, micro:bit, and RP2040 is specialized simulation work.
What it would actually take: Use a nodal-analysis or MNA solver in WebAssembly or TypeScript for the circuit core, with existing open-source MCU emulators (such as avr8js and rp2040js) for firmware execution. Scope and multimeter modeling requires careful timing and noise choices. The difficult parts are numerical stability for nonlinear components and accurate peripheral timing, which take electrical engineering and emulator-internals expertise.
