Open a page, plug in a board, click Connect. Nothing to install, any operating system. Every tool has a demo mode that runs with no hardware at all.
Hardware mode needs Chrome or Edge on a laptop or desktop (Web Serial). Demo mode works anywhere.
Open any tool and hit Try without hardware. Then plug in the board and compare.
Each demo is self-contained: firmware, wiring diagrams, a protocol doc, and the page.
Protocols are plain text. Drive any board from a serial terminal or ten lines of Python.
Six demos on pairs (or small swarms) of Seeed XIAO ESP32-C3 boards talking over ESP-NOW. Each one isolates a single idea about how wireless data actually moves. Work through them in order, or jump in anywhere.
Bench instruments reimagined as web pages, for labs where the measurement matters more than the equipment.
Each tool is a single HTML file in its own repository, served by GitHub Pages. Read the source in one sitting.
Boards speak short line-based commands like SET 2.4 and MEAS, so a serial terminal or a Python script works just as well. Every repo documents its protocol in PROTOCOL.md.
Both are built into Chrome and Edge and ask permission before touching a port. No per-OS driver installs.
Each repo ships the microcontroller code (mostly CircuitPython) plus wiring diagrams in wiring/.
