Aktuálna revízia z 17:53, 18. marec 2024
Toto je základný príklad na bezdrôtový prenos dát. Jeden micro:bit je napájaný z batérie a vykonáva samotné merania, tie pošle cez rádiový kanál druhému micro:bitu, ktorý je pripojený k počítaču a všetky dáta, ktoré prijme hneď prepošle po sériovej linke (resp. USB) do počítača, kde ich môžeme sledovať buď priamo v MakeCode prostredí, alebo inom terminálovom programe.

})

ToDo
Nasleduje drobná modifikácia, kde nebudeme posielať číslo, ale celý reťazec s viacerými meraniami, v tomto prípade oddelenými čiarkou.
