When you open a new workspace, you are greeted with a minimalist, clean grid system. The interface is divided into three main areas:
The Top Toolbar: This is your component library. It contains power sources, passive components, semiconductors, and measurement tools.
The Main Grid Workspace: This is where you will place, connect, and interact with your components.
The Bottom Control Bar: This contains the simulation controls (Play, Pause, Reset), the workspace settings, and the trash icon. 🔌 Building Your First Circuit: Step-by-Step
To understand how EveryCircuit works, let's build a classic LED circuit powered by a 9V battery. Step 1: Placing Components
Look at the top toolbar and find the DC Voltage Source (represented by a battery symbol or a simple circle with + and -). Tap it, and then tap on the workspace to place it. Find the Resistor symbol. Tap and place it on the grid.
Find the LED (Light Emitting Diode) symbol. Tap and place it on the grid.
Find the Ground symbol (three horizontal lines decreasing in size). Crucial Rule: EveryCircuit requires a ground component in every circuit to calculate voltage potentials accurately. Step 2: Wiring Components Together Wiring in EveryCircuit is incredibly intuitive.
Tap the node (the small circle at the end of a component's terminal) of the battery.
Tap the node of the resistor. EveryCircuit will automatically draw a clean, right-angled wire between them.
Repeat this process to connect the resistor to the LED, the LED to the ground, and the ground back to the negative terminal of the battery. Step 3: Adjusting Component Values By default, EveryCircuit assigns standard values (like for a resistor). To change these:
Tap on the component you want to modify (e.g., the resistor).
A small wrench or gear icon will appear, along with a circular dial on the side. Spin the dial to increase or decrease the value. You can change units dynamically from ohms ( Ωcap omega ) to kilo-ohms ( ) or mega-ohms ( ⚡ Understanding the Real-Time Simulation
Once your circuit is wired and grounded, tap the Play button at the bottom of the screen. This is where EveryCircuit shines.
Moving Dots (Current): You will see small yellow dots moving through the wires. These represent the flow of conventional electric current. The faster they move, the higher the current.
Color Gradients (Voltage): The wires themselves will change color or brightness based on voltage. Green usually represents positive voltage, while gray or black represents ground/zero voltage.
Interactive Components: You can interact with components while the simulation is running. Tap a switch to open or close it. Turn a potentiometer dial and watch the LED grow dimmer or brighter in real time! 🔬 Advanced Analysis: Using the Oscilloscope
To truly understand what is happening in a dynamic circuit (like an AC circuit or an oscillator), you need to see the waveforms. EveryCircuit has a built-in, easy-to-use virtual oscilloscope. How to Plot Waveforms Default mode when any voltage source has a
Tap on any component or specific wire node you want to monitor.
Look for the small icon that looks like an eye or a waveform (the "Tune" or "Watch" button).
An oscilloscope display will slide out at the bottom or side of the screen. It will plot voltage or current over time. Oscilloscope Controls
Scale: You can pinch or use the dial to adjust the time scale (X-axis) and the amplitude scale (Y-axis).
Multi-channel: You can tap multiple components to display multiple colored waveforms simultaneously, allowing you to compare input vs. output signals easily. 🧰 EveryCircuit Component Library Overview

To make the most out of your EveryCircuit experience, keep these professional tips in mind:
Watch Your Grounding: If your simulation gives wild numbers or doesn't run, 90% of the time it is because you forgot to add a Ground component.
The "Slow Motion" Feature: If you are analyzing a very high-frequency circuit, the dots might move too fast to see. You can pause the simulation and use the step-by-step forward button to watch the circuit state change microsecond by microsecond. Solver type: Backward Euler integration (implicit
Check the Community Tab: Don't start from scratch every time. Use the search bar in the community tab to find examples of "buck converters," "audio amplifiers," or "flip-flops" to see how others built them.
Mind the Power Limits: Just like in real life, pushing too much current through a component can cause "simulated" damage or yield unrealistic results. Always calculate your power dissipation (
If you are looking to learn more or need help with a specific circuit concept, I can provide you with a custom circuit walkthrough, explain the behavior of a specific component (like Op-Amps or Transistors), or help you debug a circuit that isn't working properly. What are you building today?
While there is no single "official" manual in a standard book format, the EveryCircuit User Manual (often found as a community-contributed tutorial document) and the official website documentation detail several key features for building and simulating circuits. Core Interactive Simulation Features
Dynamic Visualizations: The simulator provides real-time animations of voltage waveforms and current flows directly on the schematic. You can observe capacitor charges and current movement as "dots" that speed up or slow down based on magnitude.
Real-Time Parameter Adjustment: Using an analog control knob, you can adjust circuit parameters (like resistance or frequency) while the simulation is running. The circuit responds instantly to these changes without needing a restart.
Touch/Gesture Interaction: On mobile, you can generate arbitrary input signals by moving your finger across the screen or toggle switches with a single tap.
Automatic Wire Routing: The schematic editor automatically routes wires between components to maintain a clean layout, using a grid-based "digital breadboard" system.
Multi-Signal Oscilloscope: You can plot up to four voltages or currents simultaneously. It supports X-Y mode to plot one signal against another (e.g., I-V curves) and features a "stack mode" for better readability of multiple traces. Advanced Analysis Capabilities EveryCircuit: Animated interactive circuit simulator
An "EveryCircuit manual" isn’t just a dry list of instructions—it is a guide to a living, breathing laboratory where equations transform into dynamic animations. Whether you are a student visualizing Ohm's law or an engineer prototyping an oscillator on the go, EveryCircuit turns your screen into an interactive breadboard. The Core Essentials: Bringing Circuits to Life
Visualize the Invisible: Instead of static lines, EveryCircuit uses animated current flows and voltage waveforms displayed directly on your schematic. You can literally see charges moving through wires, providing instant intuition into how your circuit operates.
The Power of the Knob: Adjustment is tactile. By using the analog control knob (the wrench icon), you can tune resistance, capacitance, or voltage in real-time while the simulation is running. The circuit responds immediately to your changes.
Tap to Interact: Switches and buttons aren't just symbols; they are functional. A single tap on a switch symbol during a simulation toggles its state, allowing you to test logic gates or 555 timers on the fly. Advanced Diagnostics & Analysis EveryCircuit - Apps on Google Play
EveryCircuit is an interactive mobile and web-based circuit simulation tool that allows users to build, test, and visualize electronic circuits in real time. Unlike traditional SPICE simulators, it emphasizes animated visualization (moving electrons, color-coded voltages, current flow). However, EveryCircuit does not ship with a traditional monolithic PDF manual. Instead, its “manual” is distributed across several built-in and online resources.
EveryCircuit’s public gallery contains thousands of user-uploaded circuits with descriptions. Many advanced users include step-by-step explanations in the circuit notes. Searching for “tutorial” or “explanation” inside the gallery provides practical, example-driven documentation.
EveryCircuit is not a SPICE derivative. It uses a modified nodal analysis (MNA) solver optimized for real-time, interactive visualization. Its core trade-off is accuracy for speed: time steps are adaptive but capped to maintain >30 fps.
