Circuit Champ

Circuit Champ 2 is a hands-on electronics learning app for curious beginners and circuit enthusiasts.

Build a circuit by placing batteries, resistors, bulbs, LEDs, switches, and measuring tools on the workbench. Connect components with wires, run the simulation, and see how current and voltage affect the circuit.

Learn through guided training levels and challenges, or use the sandbox to test your own ideas. Try series and parallel circuits, explore resistor values, check polarity, use a multimeter, and discover why a component can glow, dim, or overload.

Features:

Drag-and-drop circuit building
Interactive wiring and live simulation
Guided electronics learning levels
Sandbox experiments for open-ended practice
LEDs, bulbs, batteries, resistors, switches, and measurement tools
Circuit progress and optional cloud saves
Circuit Champ Pro is a one-time optional purchase that removes ads and increases the cloud-save limit.
