Features & Capabilities

PROTO - Circuit Simulator is a powerful, real-time electronic circuit simulation tool designed for learners, hobbyists, and professionals. It allows you to build, simulate, and analyze electronic circuits using a wide range of analog and digital components, supporting projects involving Raspberry Pi, Arduino, and ESP32.

The extension offers intuitive features including voltage and current animations, a four-channel oscilloscope, parameter adjustments, and multi-format export options (PNG, JPG, PDF). It supports simulation of logic circuits, digital gates, sensors, and complex ICs with an interface that facilitates easy component copying and circuit sharing. Additional packs provide even more components like analog devices, TTL and CMOS ICs, and sensors. Future updates promise Arduino support and video tutorials to enhance learning. PROTO is ideal for anyone wanting a comprehensive electronics simulator accessible directly in their browser.

User Reviews

Users praise PROTO for solid circuit simulation and clear component details, plus beginner-friendly design. Recurrent drawbacks are a confusing, hard-to-edit UI, missing essential tools like an oscilloscope, and features locked behind payments. Several reviews also note bugs and reliability concerns, plus access issues with purchased packs and perceived lack of maintenance. Overall, strong concept with notable usability and feature gaps.

Pros

Powerful circuit simulation and building capabilities.
Clear details on each component.
Beginner-friendly and great for learning.
Easy to test simple circuit ideas with a limited free component set; nice design.
Pleasant UX and design that feels comfortable to use.

Cons

Editing circuits and components is often cumbersome; parameters (e.g., transistor) can be hard to modify and the UI is confusing.
Missing essential features and tools (notably an oscilloscope/CRO); plus many features are behind paywalls or priced high.
Bugs and reliability concerns (some components behave unexpectedly) and reports of issues with purchased packs; concerns about maintenance/downsides being ignored.

I love the app but I wish that the proto team would add layers for the sandbox and you can connect any layer to the other ones

Very nice app. Wonderful for beginners and hobbyists. I really enjoy it. Only a few things I would like for you to add. 1: variable capacitor. 2: loud speaker 3: the ability to cut/copy and paste circuits rather than having to rebuild it from scratch.
