Piano
Two-octave landscape piano (480x320) with polyphonic touch and chords.
Installable browser demos — MicroPython or Pyodide — that run the same PyDevices examples as MCUs and CPython, here inside the browser with PyScript. Use them to explore drawing, input, widgets, and LVGL without flashing a board first.
Choose MicroPython or Pyodide on a card and the demo starts automatically. The first load may take a few seconds while the runtime downloads; featured demos stay pinned at the top. Each card has MicroPython and Pyodide links.
Hidden setup installs the demo; the visible mpy-editor is just the lesson you edit and Run.
An interactive MicroPython prompt with mip ready for installing examples.
A bouncing square driven by async / await multimer.sleep_ms so the tab stays responsive.
Python listens for an HTML button click via create_proxy and updates the canvas plus page text.
