About
There are plenty of circuit simulators available on the market. Just read their ads: high performance, extremely fast, industry-standard (i.e. SPICE), easy to use, highly intuitive. If you want to see if a tool is worth using, try it yourself. That's what many NL5 users already did. I hope they will share their encouraging stories soon. A few words about what should you expect from NL5. It is not one more SPICE (and not even close), nor is it a SPICE replacement. For some tasks NL5 is far superior, for others simply good, and some tasks are not for NL5 at all.

About
Sensbench is a browser-based circuit and microcontroller simulator for learning, prototyping, and testing Arduino, ESP32, Raspberry Pi Pico, and other supported boards. Users place virtual boards and components on a breadboard, connect circuits, edit sketches, compile firmware, and run it in an emulated microcontroller while viewing serial output and component behavior. It also supports SPICE analog simulation and mixed digital-analog circuits. Guided examples and virtual sensors, displays, LEDs, relays, and other parts are included. An optional AI builder turns a written project request into a parts list, wiring plan, and firmware, while an MCP server lets compatible AI clients operate the workbench. The core simulator is free to use in a web browser; optional AI credits and subscription plans add AI usage and project features. Sensbench also sells physical project kits with pre-flashed boards and guides, including kits designed to connect to Home Assistant over local Wi-Fi.
