EveryCircuit Free

Stop Simulating. Start Engineering. Build Working Circuits Without Burning a Single Component.

EveryCircuit Free transforms your Android device into a real-time electronics laboratory. Instead of guessing whether a transistor will bias correctly or a capacitor will discharge at the right rate, you place components on a virtual breadboard and watch the simulation run instantaneously. This app eliminates the cost, time, and safety risks of physical prototyping, letting you test, iterate, and debug circuit designs anywhere—on a bus, during a lecture, or at your desk.

Core Simulation Tools and Interactive Controls

The app provides a complete set of digital and analog components, each with adjustable parameters. You drag components from a library, connect them with virtual wires, and tap any node to probe voltage or current. The simulation engine updates continuously, showing animated current flow and real-time oscilloscope traces. You can pause the simulation, change resistor values mid-operation, or swap a diode for a Zener variant to observe immediate effects on circuit behavior.

• Real-Time Analog Simulation Engine computes nodal voltages and branch currents at 30 frames per second, displaying live waveforms on an integrated oscilloscope with adjustable timebase and voltage scales.
• Component Library with 30+ Parts includes resistors, capacitors, inductors, diodes, BJTs, MOSFETs, op-amps, 555 timers, logic gates, flip-flops, and a signal generator with sine, square, and triangle outputs.
• Interactive Probing and Measurement allows tapping any wire to read voltage, current, or power dissipation, while the oscilloscope probe can be attached to multiple nodes for comparative waveform analysis.

Key Advantages for Learning and Prototyping

EveryCircuit Free focuses on immediate feedback. When you change a capacitor from 10 µF to 100 µF, the charging curve on the oscilloscope updates within one simulation tick. This instant response helps you understand component relationships without waiting for hardware setup. The clean interface avoids menu clutter—most adjustments happen via pinch-to-zoom gestures and direct value entry. Circuits can be saved to local storage and reopened later for continued work or sharing with classmates.

• Zero Hardware Risk eliminates blown components, overheating issues, and battery drain, allowing unlimited experimentation with high-voltage or high-frequency designs.
• Visual Current Animation uses flowing dots to show current direction and magnitude, making Kirchhoff’s laws and mesh analysis intuitively visible without calculation.
• Export and Share saves circuit files as .ec format for loading on other devices or sending via email, useful for collaborative debugging or homework submission.
