Sakani, kuyankhulana, ntchito yoyesa, kusankha, kulemba ntchito, kusintha - njirayo ndi yovuta komanso yomveka kwa aliyense wa ife - onse olemba ntchito ndi wogwira ntchito.
Watsopano alibe luso lapadera lofunikira. Ngakhale katswiri wodziwa zambiri amayenera kusintha. Oyang'anira amakakamizidwa ndi mafunso a ntchito zomwe angapatse wogwira ntchito watsopano poyambira komanso nthawi yochuluka yoti amupatse? Kuonetsetsa chidwi, kutengapo mbali, kuyendetsa ndi kuphatikiza. Koma musaike pachiwopsezo ntchito zovuta zamabizinesi.
Kuti tichite izi, timayambitsa ma projekiti amkati. Amakhala ndi magawo odziyimira pawokha. Zotsatira za ntchito yotere zimakhala ngati maziko a zochitika zotsatila ndikulola watsopano kuti adziwonetse yekha, agwirizane ndi gulu ndi ntchito yosangalatsa komanso popanda chiopsezo cholephera ntchito yofunika. Izi zikuphatikiza kudziwa zambiri, kukumana ndi anzanu, komanso mwayi wowonetsa mbali yanu yabwino pomwe palibe zoletsa zoletsa cholowa.
Chitsanzo cha chitukuko chopatsirana choterechi chinali mutu wa sikirini yozungulira yotengera mawonekedwe a strobe yokhala ndi kuthekera kowonetsa chithunzi chosunthika chojambulidwa pa foni yam'manja. Zofananira zitha kupezeka .
Ntchitoyi idachitidwa motsatizana ndi antchito angapo ndipo idzapitilizidwa ndi atsopano nthawi yonse yomwe akukwera (kuyambira masabata awiri mpaka mwezi, kutengera luso ndi luso).
Masiteji anali motere:
a) lingalirani pamapangidwe (pophunzira zitsanzo zomwe zilipo, mafotokozedwe a ma analogue, kuwonetsa zopanga);
b) kupanga chojambula cha dera ndikuchiyika pa bolodi;
c) kupanga ndondomeko yosamutsa zithunzi kuchokera pa foni kupita ku chipangizo;
d) perekani kuwongolera kuchokera pa foni yam'manja kudzera pa Bluetooth LE.
Njira yoyambira inali kugwiritsa ntchito chinthu chophatikizika kwambiri, monga sipinari ya petal atatu, yomwe, ikazunguliridwa pamanja, idayamba kuwonetsa zolembedwa. Panali gawo la BLE mu petal imodzi, ma LED khumi a RGB chachiwiri, chachitatu sensor sensor, ndi batire pakati. Chithunzi chozungulira chinapangidwa ndipo zoyeserera zoyambirira zidachitika. Zinali zoonekeratu kuti mlingo wa khalidwe la chithunzi ndi wotsika kwambiri, chigamulocho ndi chaching'ono, zotsatira za masewera zimakhala zaufupi, ndipo mphamvu ndizochepa. Ndipo ma spinner ndi zinthu zakale mwachangu momwe zidawonekera. Zinaganiziridwa kuti zikweze kapamwamba ndikupanga chophimba chozungulira cha strobe. Pang'ono ndi pang'ono, angagwiritsidwe ntchito pazinthu zothandiza paziwonetsero ndi misonkhano, ndipo chidwi cha mayankho otere sichidzatha posachedwa.
Ponena za kapangidwe kameneka, panali mafunso awiri akuluakulu: momwe mungayikitsire ma LED (mu ndege yowongoka, monga momwe tawonetsera pamwambapa, kapena pamtunda wopingasa) ndi momwe mungagwiritsire ntchito bolodi lozungulira ndi ma LED.
Zolinga zamaphunziro, ma LED adayikidwa mundege yopingasa. Ponena za kupatsa mphamvu bolodi, panali chisankho chofunikira: mwina titenge injini yamagetsi, yomwe imakhala yochuluka, yaphokoso, koma yotsika mtengo, kapena timagwiritsa ntchito njira yabwino kwambiri yogwiritsira ntchito magetsi osagwiritsa ntchito magetsi awiri - imodzi pa galimoto, ina. pa bolodi. Yankho, ndithudi, ndi yokongola, koma yokwera mtengo komanso yowononga nthawi, chifukwa ... makola amayenera kuwerengedwa kaye kenako ndikuvulala (makamaka osati pa bondo).
Izi ndi zomwe zotsatira zake zimawonekera
Kukhazikika kwazinthu zopangidwa mochuluka ndizoti ndalama iliyonse yowonjezera pamtengo imakhala yofunika. Kupambana kungadziwike ndi mtengo wa zochepa chabe. Choncho, nthawi zambiri zimakhala zofunikira kusankha njira yochepetsetsa koma yotsika mtengo kuti wopangayo akhalebe wopikisana ndi malonda. Chifukwa chake, poganiza kuti chiwonetsero cha rotary chidzayikidwa pakupanga kwakukulu, wopangayo adasankha mota yoyendera.
Ikayambitsidwa, chojambulacho chinawala modzudzula, ndikupanga phokoso ndikugwedeza tebulo. Mapangidwe omwe adatsimikizira kukhazikika adakhala olemetsa komanso ochulukirapo kotero kuti sizinali zomveka kuzibweretsa ku chithunzi chopanga. Posangalala ndi kupambana kwapakatikati, tinaganiza zosintha injiniyo ndi thiransifoma yozungulira yokhala ndi mpweya. Chifukwa china chinali kulephera kuyatsa injini kuchokera padoko la USB la kompyuta.
Bolodi la LED limachokera pa module yathu ya RM10 ndi madalaivala asanu ndi limodzi a LED. .
Madalaivala ali ndi mayendedwe 16 omwe amatha kuwongolera aliyense payekha. Chifukwa chake, madalaivala 6 otere ndi ma 32 RGB ma LED onse amatha kuwonetsa mitundu 16 miliyoni.
Kulunzanitsa ndi kukhazikika kwa chithunzicho, masensa awiri a magnetoresistive Hall adagwiritsidwa ntchito .
Dongosololo linali losavuta - sensa imapereka kusokonezeka kwa kusintha kulikonse kwa bolodi, malo a ma LED amatsimikiziridwa ndi wotchi pakati pa madutsa awiri ndi azimuth awo ndi kuwala amawerengedwa mu 360-degree scan.
Koma china chake chalakwika - mosasamala kanthu za kuthamanga kwa bolodi, sensayo idatulutsa kusokoneza kumodzi kapena kuwiri pakudutsa. Chifukwa chake, chithunzicho chidakhala chosawoneka bwino komanso chopindika mkati.
Kusintha masensa sikunasinthe zinthu, kotero kuti sensa ya Hall inasinthidwa ndi photoresistor.
Ngati wina ali ndi malingaliro oti chifukwa chiyani sensor ya magnetoresistive ingachite motere, chonde gawanani mu ndemanga.
Pamwamba pa bolodi
Ndi sensa ya kuwala, chithunzicho chikuwoneka bwino, koma chimatenga pafupifupi masekondi 30 kuti chikhazikike. Izi zimachitika pazifukwa zingapo, chimodzi mwazo ndi kuzindikira kwa nthawi. Izi ndi nkhupakupa 4 miliyoni pa sekondi imodzi, zogawidwa ndi madigiri 360 ndi chotsalira, zomwe zimabweretsa kupotoza mu chithunzi chotuluka.
M'mawotchi aku China strobe, chithunzicho chimayikidwa mumasekondi pang'ono pamtengo woti gawo laling'ono la bwalo silinawonetsedwe: pali malo opanda kanthu pa chithunzi chozungulira, chosawoneka palemba, koma chithunzicho sichikwanira.
Komabe, mavuto sanathe. Microcontroller sangathe kupereka mlingo wofunikira wotumizira deta kwa chiwerengero chotheka cha mithunzi (pafupifupi 16 MHz) - chinsalu chimapanga 1 chimango pamphindi, chomwe sichikwanira diso la munthu. Mwachiwonekere, muyenera kuyika chowongolera chosiyana pa bolodi kuti muwongolere chithunzicho, koma pakadali pano lingaliro lapangidwa kuti lisinthe MBI5030 ndi. . Pali mitundu 7 yokha, kuphatikiza yoyera, koma izi ndizokwanira kuchita gawo la pulogalamuyo.
Chabwino, ndipo chinthu chofunikira kwambiri, chifukwa cha zomwe ntchito yophunzitsayi idayambika, ndikukhazikitsa microcontroller ndikuwongolera kudzera pakugwiritsa ntchito pa smartphone.
Kujambulaku kumafalitsidwa kudzera pa Bluetooth mwachindunji kudzera pa nRF Connect, ndipo mawonekedwe ogwiritsira ntchito akupangidwa.
Chifukwa chake, zotsatira zapakatikati za gulu la relay ndi izi:
Chophimba chozungulira chimakhala ndi mzere wa ma LED 32 ndi mawonekedwe a 150 mm. Imawonetsa mitundu ya 7, imayika chithunzi kapena malemba mumasekondi a 30 (omwe si abwino, koma ovomerezeka kuyamba nawo). Pogwiritsa ntchito kugwirizana kwa Bluetooth, mukhoza kupereka lamulo kuti musinthe chithunzicho.
Ndipo izi ndi momwe zimawonekera
Ndipo kuti otukula achichepere atsopano aphunzire bwino, chomwe chatsala ndikuthetsa ntchito zotsatirazi:
Gonjetsani kusowa kwa microcontroller RAM kuti muwonetse mitundu yonse ya utoto. Sinthani pulogalamu yopangira ndi kutumiza zithunzi zokhazikika kapena zosunthika. Perekani mawonekedwe omalizidwa. Tidzakudziwitsani.
PS Inde, nditamaliza ntchito pa Bluetooth LE () tidzapanga ndi kukhazikitsa mtundu wa Wi-Fi/Bluetooth pa ESP32 Koma imeneyo ikhala nkhani yatsopano.
