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.
