Re hlobolisa lithapo tsa rona tsa mehala, re sotha lithapo tse mebala hammoho, ebe re li teneha.
Kamora moo, solder ho mabitso a boto joalo ka setšoantšong:
Ke eona, hona joale bakeng sa tlhahlobo ea ho qetela, re kenya li-sensor likarolong tsa selikalikoe, sengoathoana sa plywood holimo, re tsosolosa molaoli (re beha betere e nang le pene cap ho photodiode).
Ka nako e ts'oanang, LED ho Arduino e lokela ho panya 'me SMS ea teko e lokela ho fihla.
Ka mor'a moo, tlosa sekoahelo ho photocell 'me u ee ho tlatsa metsi ka botlolo ea polasetiki ea 1.5 lithara.
Re beha botlolo holim'a plywood 'me haeba metsotso e' maloa e se e fetile ho tloha ha e buletsoe, re khutlisetsa cap ho photoresistor (ho etsisa ho likela ha letsatsi).
Ka mor'a metsotso e meraro, LED e ho Arduino e tla khantša, 'me u lokela ho fumana SMS e nang le boima ba boima ba lik'hilograma tse ka bang 1 libakeng tsohle.
Kea u babatsa! Sistimi e kopantsoe ka katleho!
Haeba joale re qobella tsamaiso hore e sebetse hape, joale mohala oa pele oa boima o tla ba le zero.
E, maemong a sebele ho bohlokoa ho lebisa photoresistor ka holimo.
Joale ke tla fana ka bukana e khuts'oane ea mosebelisi:
- Kenya li-gauge tsa khatello tlas'a marako a ka morao a hives (beha leballo/boto e botenya ba ~ 30mm ka tlas'a tse ka pele)
- Etsa moriti oa photoresistor 'me u kenye betri - LED e lokela ho panya' me u fumane SMS ea teko e nang le mongolo "INITIAL BOOT OK"
- Beha yuniti e bohareng ka sebaka se seholo ho tloha ho li-hives le hore lithapo li se ke tsa kena-kenana ha u sebetsa le linotsi.
Mantsiboeeng a mang le a mang, ka mor'a hore letsatsi le likele, u tla fumana SMS e nang le liphetoho tsa boima ba hau bakeng sa letsatsi le ho tloha motsotsong oa ho qala.
Ha matla a betri a fihla ho 3.5V, SMS e tla fela ka mohala "!!! SHAJA BETHER!!!"
Nako ea ts'ebetso ea betri e le 'ngoe ea 2600mAh e ka ba khoeli.
Haeba betri e nkeloa sebaka, liphetoho tsa letsatsi le letsatsi boima ba hives ha li hopoloe.
Ke'ng e latelang?
- Fumana mokhoa oa ho kenya tsena tsohle morerong oa github
- Qala malapa a 3 a linotši ka har'a hives ea tsamaiso ea Palivoda (kapa linaka ho batho)
- Eketsa "buns" - ho lekanya mongobo, mocheso, 'me habohlokoa ka ho fetisisa - ho hlahloba molumo oa linotsi.
Ke tsohle hajoale, ke tsa hau ka tieo, mohlokomeli oa linotsi oa motlakase Andrey
