Mawonekedwe a LEDndi zinthu zamagetsi, ndipo nthawi zina pangakhale mavuto.Pansipa, tikuwonetsani njira zingapo zodziwika bwino zothetsera mavuto.
01 Chifukwa chiyani masekondi angapo a mizere yowala kapena chithunzi chosawoneka bwino pawindo la LED chikayatsidwa koyamba?
Pambuyo polumikiza chowongolera chachikulu pakompyuta, bolodi yogawa HUB, ndi chophimba bwino, ndikofunikira kupereka a+ 5V magetsikwa wowongolera kuti awonetsetse kuti akugwira ntchito bwino (panthawiyi, musalumikize mwachindunji ku voteji ya 220V).Panthawi yoyatsa magetsi, pakhala masekondi angapo a mizere yowala kapena "chithunzi chowoneka bwino" pazenera, zomwe ndizochitika zoyeserera, kukumbutsa wogwiritsa kuti chophimba chatsala pang'ono kuyamba kugwira ntchito bwino.Pakadutsa masekondi a 2, chodabwitsachi chidzazimiririka ndipo chinsalu chidzalowa mumayendedwe abwinobwino.
02 Chifukwa chiyani imalephera kuyika kapena kulumikizana?
Zifukwa za kulephereka kwa kulumikizana ndi kulephera kutsitsa ndizofanana, zomwe zitha kuyambitsidwa ndi zifukwa zotsatirazi.Chonde yerekezerani zomwe zalembedwazi ndi ntchito:
1. Onetsetsani kuti zida zowongolera zimayendetsedwa bwino.
2. Yang'anani ndikutsimikizira kuti chingwe chogwirizira chomwe chimagwiritsidwa ntchito kulumikiza wolamulira ndi mzere wolunjika, osati mzere wodutsa.
3. Yang'anani ndikutsimikizira kuti waya wolumikizana ndi doko ilibe ndipo palibe kumasuka kapena kutsekeka mbali zonse ziwiri.
4. Yerekezerani pulogalamu yoyang'anira skrini ya LED ndi khadi yowongolera yomwe mwasankha kuti musankhe mtundu wolondola wazinthu, njira yotumizira, nambala ya doko la serial, ndi kuchuluka kwa ma serial transmission.Khazikitsani ma adilesi ndi kuchuluka kwa kufalikira kwa zida zowongolera molingana ndi chithunzi chosinthira chojambulira mu pulogalamuyo.
5. Yang'anani ngati kapu ya jumper ndi yotayirira kapena yotsekedwa;Ngati chipewa chodumphira sichikumasuka, chonde onetsetsani kuti kolowera kapu ya jumper ndikolondola.
6. Ngati mutayang'ana ndi kukonza zomwe zili pamwambazi, padakali vuto pakukweza, chonde gwiritsani ntchito multimeter kuti muyese ngati doko lachinsinsi la kompyuta yolumikizidwa kapena hardware system yawonongeka, kutsimikizira ngati iyenera kubwezeredwa kwa wopanga makompyuta. kapena zida zowongolera zoyeserera.
03 Chifukwa chiyani chophimba cha LED chikuwoneka chakuda kwathunthu?
Pogwiritsa ntchito machitidwe owongolera, nthawi zina timakumana ndi zochitika zazithunzi za LED zomwe zimawoneka zakuda kwambiri.Chochitika chomwecho chikhoza kuyambitsidwa ndi zifukwa zosiyanasiyana, ngakhale mawonekedwe a chinsalu akuda akhoza kusiyana malingana ndi machitidwe kapena malo osiyanasiyana.Mwachitsanzo, imatha kukhala yakuda ikayatsidwa, imatha kukhala yakuda ikatsitsa, kapena imatha kukhala yakuda ikatumiza, ndi zina zotero:
1. Chonde onetsetsani kuti zida zonse, kuphatikiza zowongolera, zimayatsidwa bwino.(+5V, osasintha kapena kulumikizana molakwika)
2. Yang'anani ndikutsimikizira mobwerezabwereza ngati chingwe chogwirizira chomwe chimagwiritsidwa ntchito kulumikiza chowongolera ndi chotayirira kapena chatsekedwa.(Ngati asanduka wakuda panthawi yotsitsa, ndiye kuti chifukwa cha izi, ndiye kuti, amasokonekera chifukwa cha mizere yolumikizana yotayirira panthawi yolumikizirana, kotero chinsalu chimasanduka chakuda. Musaganize kuti thupi lotchinga silikuyenda. , ndipo mizereyo singakhale yotayirira, Chonde yang'anani nokha, zomwe ndizofunikira kuthetsa vutoli mwachangu.)
3. Yang'anani ndikutsimikizira ngati gulu logawa la HUB likugwirizana ndi chinsalu cha LED ndipo khadi lalikulu lolamulira likugwirizanitsidwa mwamphamvu ndikuyika mozondoka.
04 Chifukwa chomwe chinsalu chonse cha board board sichikhala chowala kapena chowoneka bwino
1. Yang'anani m'maso zingwe zamagetsi, zingwe za riboni za 26P pakati pa matabwa a unit, ndi magetsi owonetsera mphamvu kuti muwone ngati akugwira ntchito bwino.
2. Gwiritsani ntchito ma multimeter kuti muyese ngati gulu la unit lili ndi magetsi abwino, ndiyeno muyese ngati mphamvu yamagetsi yamagetsi yamagetsi ndi yachilendo.Ngati sichoncho, zimaganiziridwa kuti gawo la mphamvu ndilolakwika.
3. Yezerani voteji yotsika ya gawo la mphamvu ndikusintha kusintha kwabwino (pafupi ndi chizindikiro cha kuwala kwa gawo la mphamvu) kuti mukwaniritse mphamvu yamagetsi.
