Overview
Circuit Builder is Tebemo's online schematic editor and simulator. Design circuits, connect components, and run physics-based simulations — all in the browser.
What you can do
- Design — Place and connect from a library of 26 components: resistors, capacitors, transistors, MOSFETs, relays, and more
- Simulate — Run real-time simulations with animated current flow, voltage measurement, and failure detection
- Collaborate — Edit boards simultaneously with other users with live cursors
- Share — Share boards via link or email with view-only or edit permissions
- Export — Save circuits as JSON for backup or transfer
Key concepts
Board — A circuit project. Each board has a name, a canvas, and a simulation state. You can have multiple boards.
Canvas — The main drawing area where you place components and draw wires between them.
Component — A circuit element (resistor, LED, battery…) with configurable properties that affect simulation behavior.
Simulation — A physics engine that models current flow, voltage, power dissipation, and component temperature in real time.
Collaboration session — A live connection between all users editing the same board. Changes are synchronized instantly.
Who uses Circuit Builder
- Students learning electronics — place a battery, a resistor, and an LED, connect them, and watch current flow in simulation
- Educators — prepare circuit diagrams for lessons and share them in read-only presentation mode
- Hobbyists — design and test circuits before building physical prototypes
