Anthu ambiri amakumana ndi mavuto osiyanasiyana pakukhazikitsa ndikuwonetseratu kuwonetsa kwa LED. Akalumikizana ndi kuwonetsera kowonekera kwa LED ndikuwonetseratu, opanga ma LED ambiri alibe malangizo, kotero ogwiritsa ntchito onse ndi ovuta, sindikudziwa ngati mwakumana ndi mafunso otsatirawa? Ngati simungathe kuyikweza, zowonekera, zenera lakuda, ndi zina zambiri, mukudabwa kuti chikuyambitsa ndi chiyani?
Funso 1: Chophimbacho ndi chakuda
1. Chonde onetsetsani kuti ma hardware onse kuphatikizapo makina owongolera amayendetsedwa bwino. (+ 5V, osatembenuka, kulumikizana molakwika)
2. Fufuzani ndipo mutsimikizireni mobwerezabwereza ngati chingwe chosakira chomwe chimagwiritsidwa ntchito kulumikizana ndi wolamulira sichimasuka kapena ayi. (Ngati mdima ukugwira, mwina chifukwa cha izi, ndiye kuti, njira yolumikizirana imasokonezedwa chifukwa cha kusasunthika kwa kulumikizana panthawi yolumikizirana, chinsalucho chimakhala chamdima, ndipo chinsalucho sichili yasunthidwa, ndipo mzerewo sungamasulidwe. Chonde onani, ndikofunikira kuthana ndi vutoli mwachangu.)
3. Onetsetsani ndikutsimikizira ngati chophimba cha LED cholumikizidwa ndi bolodi logawira HUB yolumikizidwa ndi khadi yayikulu yolumikizira yolumikizidwa mwamphamvu ndikuyika.
Funso 2: Kanemayo akusintha kapena owala
Mukalumikiza zowonera pazenera pamakompyuta ndi bolodi logawira HUB ndi chinsalu, muyenera kupereka + 5V mphamvu kwa woyang'anira kuti agwire bwino ntchito (potere, musalumikizane ndi 220V). Pakadali magetsi, padzakhala masekondi ochepa amizere yowala kapena "mawonekedwe osalala" pazenera. Mzere wowala kapena "mawonekedwe osowa" ndichizolowezi choyesa, chokumbutsa wogwiritsa ntchito kuti chinsalucho chatsala pang'ono kuyamba ntchito yabwinobwino. Pakadutsa masekondi awiri, chodabwitsacho chimachotsedwa ndipo chinsalucho chimayamba kugwira ntchito bwino.
Funso 3: Chophimba chonse cha unit board sichowala kapena kuda
1. Onani zowoneka ngati chingwe cholumikizira magetsi, chingwe cha 26P pakati pama board unit, ndi chizindikiro cha module yamagetsi ndichabwino.
2. Gwiritsani multimeter kuyeza voteji wabwinobwino wa bolodi wagawo, ndiyeno kuyeza ngati voteji linanena bungwe la gawo mphamvu yachibadwa. Ngati sichoncho, aweruzidwa kuti gawo lamagetsi ndilolakwika.
3. Measure voltage of the module yamagetsi ndiyotsika, sinthani kusintha kwabwino (kusintha kwabwino kwa gawo lamagetsi pafupi ndi chowunikira) kuti voliyiyo ifike pamlingo woyenera.
Funso 4: Simungathe kunyamula kapena kulumikizana
Yankho: Malinga ndi zifukwa zomwe zili pansipa, ntchitoyi ikufanizidwa
1. Onetsetsani kuti zida zoyendetsera bwino zikuyendetsedwa bwino. (+ 5V) Chikuwala
2. Onetsetsani kuti chingwe chosakira chomwe chimagwiritsidwa ntchito polumikizira cholumikizira ndichachingwe chodutsa, osati chingwe cha crossover.
3. Chongani ndi kutsimikizira kuti siriyo doko chingwe ndi cholimba ndipo palibe lotayirira kapena kugwa pa malekezero onse.
4. Fananizani pulogalamu yoyang'anira pazenera la LED ndi khadi loyang'anira lomwe mwasankha nokha kuti musankhe mtundu woyenera wazogulitsa, njira yolumikizira yolondola, nambala yolondola ya doko, kuchuluka kwa ma transmitter ofiyira ndikuyika kuwongolera molingana ndi chithunzi cha DIP switch mu pulogalamuyo. Pang'ono pang'ono ma adilesi ndi ma serial osamutsa pazida zamagetsi.
5. Onetsetsani ngati kapu ya jumper ili yotayirira kapena yotayika; ngati kapu ya jumper siyotayirira, chonde onetsetsani kuti kapuyo ili molondola.
6. Ngati cheke pamwambapa chikusoweka kukweza, chonde gwiritsani ntchito multimeter kuti muwone ngati doko loyeserera la kompyuta yolumikizidwa kapena zida zowongolera zawonongeka kuti zitsimikizire ngati ziyenera kubwezeredwa kwa wopanga makompyuta kapena makina olamulira ndi ovuta . Kutumiza thupi kumawonekeranso.
Pakukhazikitsa ndi kukonza kwawonetseratu kuwonekera kwa LED, womangayo akuyenera kugwira ntchito yoyeserera yoyeserera kuti apewe mavuto monga kuwonongeka pazenera. Mukakumana ndi mavuto amisili, mutha kulumikizana ndi katswiri kuti akuwongolereni. Nthawi zambiri ndimakhala ndikudziwa zambiri zakukonza zowunikira zowonekera bwino za LED, ndipo ndidzakhala womasuka ndikadzakhala ndi vuto mtsogolo.
