Scratchboard

Scratchboard is a browser-based electronics design and simulation platform that lets users design circuits, write Arduino code, and test digital and analog systems without installing software or connecting physical hardware. Its primary purpose is to provide an accessible environment for learning, prototyping, and experimenting with embedded systems and electronic circuits directly in the browser. By combining schematic design, code development, and simulation, Scratchboard streamlines the workflow from concept to validated design.

The platform supports digital logic design, analog circuits, and microcontroller-based projects, including Arduino-compatible workflows. Users can place and connect components, configure parameters, and observe circuit behavior through interactive simulation, enabling step-by-step debugging and validation. Integrated code editing allows users to write, modify, and run Arduino code alongside their hardware designs, making it easier to understand the interaction between software and electronics. Because everything runs in the browser, projects are easy to start, share, and iterate on across different devices and operating systems.
