Pozdravljeni,
izdelujem avtomatsko odpiranje in zapiranje kokošnjaka glede na svetlobo z Arduino Nanom in fotouporom. Vezja samega mi ni bilo problem sestaviti, a pri programiranju sem naletel na meni prezahteven problem, kateri se mi dozdeva da bo za vas mačji kašelj. Prilagam program, katerega sem našel na tej strani .
Zanima me kako bi lahko v obstoječo kodo dodal funkcijo, da se ne bi vrata odpirala in zapirala ob vsaki nenadni spremembi svetlosti (ponoči npr. mimovozeči avtomobil, zvečer sence...), ampak bi nekako izračunaval povprečje nekaj minut, in nato če bi bilo dovolj časa dovolj temno/svetlo sprožil zapiranje/odpiranje. Torej, da bi reagiral kakih 10-15min po svitanju, in isto ko bi padel mrak šele po tem času.
Že nekaj dni berem vodiče in se igram s tem, a programiranje mi res ne leži, tako da bi bil izredno hvaležen če bi bil kdo pripravljen pomagati.
Hvala vnaprej,
Nejc

//Locking, Automatic Chicken Coop Door

//This section is for initializing things:
// Initialize the motor values to the pins 8, 7, 9.
//Pins 7 and 8 send high or low to the motor controller.
//pin 10 enables motor one on the motor controller.

Za hitre spremembe svetlobe (naprimer avto) lahko napišeš nekaj podobnega:
če je že svetlo, potem počakaj npr. 55s,
pomeri še enkrat, lahko pomeriš večkrat zaporedoma, mogoče bi lahko uporabil tudi povprečenje meritev v času 55s.
če je še bolj svetlo potem odpri ,
če ni še bolj svetlo potem ne odpri.
Povprečenje je tudi eden od načinov, kateri je pa boljši??? |

Za varnost bi lahko dodal še števec. Preveriš če so vse not in potem zapreš, da ne ostane katera zunaj.

| Saj nekaj takega bi rad naredil, a se mi ne sanja niti približno kako bi to spesnil skupaj v program... Jasno mi je kje najdem spremenljivko iz fotoupora (int lightVal = 0; ), a kako naprej mi je pa španska vas. |

Jaz bi se orientiral na uro, v povezavi z datumom (letnim časom, oziroma dolžino dneva).
Ker če bo nevihta s temnimi oblaki, se bojo vrata zaprla tudi sredi dneva. |
