Jak wiadomo herbat\u0119 zielon\u0105 zaparza\u0107 nale\u017cy w temperaturze 80\u00b0 Celsiusza. Postanowi\u0142em zrobi\u0107 prosty uk\u0142ad, kt\u00f3ry b\u0119dzie tego pilnowa\u0142. Po zagotowaniu wody w czajniku wk\u0142adam czujnik i czekam a\u017c da zna\u0107 melodyjk\u0105, \u017ce mo\u017cna zaparza\u0107 herbat\u0119 (80\u00b0C). Zaparzam w zaparzarce. Nast\u0119pnie przelewam do kubka, wk\u0142adam czujnik i czekam, a\u017c da zna\u0107 inn\u0105 melodyjk\u0105, \u017ce woda nadaje si\u0119 do pos\u0142odzenia miodem (40\u00b0C). Proste.<\/p>\n

Przy budowie czujnika korzysta\u0142em ze strony uczymy.edu.pl<\/a>.

Dzi\u0119ki za pomoc.

Przypominam jeszcze, \u017ce do grania melodii potrzebujemy biblioteki „pitches.h”. Tu<\/a> instrukcja jak j\u0105 pobra\u0107.<\/p>\n
