Fyzik\u00e1ln\u011b zaj\u00edmav\u00e1 sestava se t\u00fdk\u00e1 kombinov\u00e1n\u00ed zvuku a sv\u011bteln\u00fdch reakc\u00ed.

Nejd\u0159\u00edve je nutn\u00e9 doinstalovat bal\u00ed\u010dek k\u00f3du Kinter Academy<\/strong>. Je p\u0159\u00edmo v nab\u00eddce MakeCode, tak\u017ee jde o z\u00e1le\u017eitost n\u011bkolika sekund. Je nezbytn\u00fd, proto\u017ee cel\u00fd proces je na n\u011bm z\u00e1visl\u00fd. J\u00e1 jsem si nainstaloval i dal\u0161\u00ed roz\u0161\u00ed\u0159en\u00ed OLED<\/strong>, kter\u00fdm m\u016f\u017eeme nastavit LEDky pro r\u016fzn\u00e9 t\u00f3ny.<\/p>\n\n\n\n

\"Microbit<\/figure><\/div>\n\n\n\n

D\u00edky tomu, \u017ee je v nab\u00eddce p\u011bt tla\u010d\u00edtek, m\u016f\u017eeme pro ka\u017ed\u00e9 naprogramovat zvuk jin\u00e9 v\u00fd\u0161ky. Vlastn\u00ed k\u00f3d je pom\u011brn\u011b lehk\u00fd na sestaven\u00ed a kr\u00e1tk\u00fd, co\u017e u p\u0159\u00eddavn\u00fdch modul\u016f a roz\u0161\u00ed\u0159en\u00ed b\u00fdv\u00e1 b\u011b\u017en\u00e9. A nakonec si u\u017e m\u016f\u017eete zahr\u00e1t.<\/p>\n\n\n\n

Jde o sestavu, kter\u00e1 je snadno dostupn\u00e1, v hlavn\u00ed roli je samoz\u0159ejm\u011b micro:bit. Je vhodn\u00e1 pro dvojici \u017e\u00e1k\u016f, proto\u017ee i v takto jednoduch\u00e9m programu lze zaj\u00edmav\u011b experimentovat. Frekvence t\u00f3n\u016f se zapisuje \u010d\u00edseln\u011b, op\u011bt zaj\u00edmav\u00e1 \u00faloha pro jej\u00ed sledov\u00e1n\u00ed ve vztahu ke zvuku a jeho v\u00fd\u0161ce. V\u00fdznam pro fyziku je z\u0159ejm\u00fd, ale hlavn\u00ed p\u0159idanou hodnotu vid\u00edm v propojen\u00ed s programov\u00e1n\u00edm. V podstat\u011b jde o jednoduch\u00fd z\u00e1klad IoT.<\/p>\n\n\n\n

Jak je vid\u011bt, cel\u00fd k\u00f3d je opravdu jednoduch\u00fd, i kdy\u017e na obr\u00e1zc\u00edch nen\u00ed cel\u00fd. Sestava m\u00e1 ale podporu na webu, tak\u017ee by u\u010ditel nem\u011bl m\u00edt probl\u00e9m.<\/p>\n\n\n\n
