Ukuzinakekela kanye nokuxazulula izinkinga zamaphutha amancane ajwayelekile kumalambu e-led

Ukuzinakekela kanye nokuxazulula izinkinga zamaphutha amancane avamile ezibani ezikhonjiwe Amaphutha amancane avamile amalambu aphethwe angalungiswa futhi aqedwe nguwe. Uma kusobala ukuthi amanzi angenile noma afinyeziwe futhi ashisiwe, ungawashintsha ngezesekeli ngokwakho. Kulokhu, igobolondo liyigugu. Uma igobolondo libiza noma isethi yonke iyimbi, njengezibani zezikhukhula nezibani zasemgwaqweni, khona-ke umthombo wokukhanya nomshayeli kufanele kushintshwe, futhi ungakwazi esikhundleni sakho ufake isivalo esithile. Isiphakamiso siwukuba uthole umkhiqizi owenza lokhu futhi uthenge isethi efanayo, ulinganise usayizi futhi uthathe izithombe, futhi ungafaki umthombo wokukhanya kuwo lapho uthenga, ikakhulukazi ungayithengi ngokuhlukana, ungacabangi ukuthi ishibhile! Uma kungazelelwe kucishiwe noma kumnyama, kodwa amanye amasekhethi aphelele, okusho ukuthi, ezinye izinto zikagesi zilungile. Kulokhu, isibani ngokwaso sinovalo, okungukuthi, siphukile. Lesi simo sivame kakhulu. Siqala ukususa isibani futhi kancane sihlaziye! Thatha isibani se-LED esilula njengesibonelo, vula ikhava kuqala, futhi usikhethe eduze kwegebe lonqenqema ngensingo. Ngemva kokuvula, bheka ukuthi ukukhanya kusebenzisa umshayeli, kungakhathaliseki ukuthi ibhodi elixhunywe kuphaneli yokukhanya noma izingxenye zithengiswa kuphaneli yokukhanya. Okusho ukuthi, uhlelo oluzimele lwe-IC ne-DOB, i-IC ezimele iyinkinga kancane. Iphuzu lokuqala lokuxazulula inkinga: qala uhlole ukuthi ubuhlalu besibani busesimeni esihle yini. Uma kukhona amachashaza amnyama phakathi nobuhlalu besibani, ngokuyisisekelo kuphukile. Uma kukhona eyodwa noma ezimbili ezimbi, ungazilungisela ngokwakho. Uma kukubi kakhulu, vele ubeke esikhundleni! Ubuhlalu besibani bushile Ukuxazulula izinkinga ezimbili: kungakhathaliseki ukuthi isixhumi selambu lesibani somgwaqo esiholelekile sivaliwe, ikakhulukazi umugqa osekhanda lesibani, umugqa lapha kulula ukuwa, zama ukuwukhipha ngobumnene ngezandla zakho ukuze ubone ukuthi awuhlangene kahle yini, ukugcinwa nakho kulula, isipikili esisekhanda lesibani singaphakanyiswa nge-blade Lose.

Iphuzu lesithathu lokuxazulula inkinga: Uma kuyisixazululo se-DOB, okungukuthi, lelo lapho izingxenye zikhona zonke kuphaneli, hlola ukuthi likhona yini igebe ekuhlanganisweni kwezingxenye, ungavula amandla, bese uzama ukuwacindezela ngamunye ngamunye nge-screwdriver e-insulated ukuze uqede iphuzu lephutha. Uma iqhutshwa i-IC ezimele, kuvame kakhulu ukuthi izintambo ezixhumayo ezinhlangothini zombili ziphukile noma ukuthintana kubi, futhi ishidi lethusi liyasonteka. Ungazidayisela ngokwakho futhi uyisebenzise. Uma zingekho izinkinga ezisobala ngenhla, ungathenga enye kuphela ye-DOB. Ungazama ukushintsha umshayeli ku-IC ukuze ubone ukuthi inkinga yomshayeli noma inkinga yomthombo wokukhanya. Akekho umshayeli? Susa esinye isibani bese usishintsha! Uma ushibhile, uzobe ushibhile kuze kube sekupheleni! Uma umshayeli engavuliwe kuba yinkinga ngomthombo wokukhanya, futhi uma umshayeli evuliwe, kuba yinkinga kumshayeli! Ukugcinwa okulula komthombo wokukhanya we-LED Kulula ukuhlola nge-multimeter. Uma ingekho i-multimeter, ungaqala ufake isibani kumphathi wesibani, uvule iswishi, bese usebenzisa ama-tweezers noma okunye ukuxhuma iziphetho ezimbili zobuhlalu besibani esishile. (I-voltage yobuhlalu besibani lapha ingama-volts angu-2- 3 kuphela ayiyona ingozi) Uma ukukhanya kungakhanya ngemva kokuxhuma, bese uyicisha, thengisa ubuhlalu besibani obufanayo ngokwakho noma uyidayise ngokuqondile ngocingo lukathayela.

Uma ingakhanyi ngemuva kokuxhuma, khona-ke inkinga ayikhawulelwe lapha. Okokuqala, shintsha ubuhlalu besibani obungalungile ufake ubuhlalu besibani bese ubuthengisa ngocingo lukathayela ngaphambi kokuqhubeka nokuzama obunye ubuhlalu besibani. Ungakwazi ukuhlanganisa ubuhlalu bezibani obuningi Ake sihlole ngezigaba ndawonye ukuze sithole ububanzi bezibani zobuhlalu obungalungile kuze kutholakale bonke ubuhlalu besibani obungalungile futhi bushintshwe. Ukugcinwa okulula komshayeli we-LED Umonakalo ohlobene nezingxenye ze-elekthronikhi awukwazi ukulungiswa. Lapha singathola kuphela izindawo ezithile lapho amalunga e-solder ewa khona ukuze alungiswe kalula. Sicela uqaphele ukuthi akubona bonke abashayeli bomkhiqizi ofanayo kanye nokucaciswa okufanayo kanye nemodeli akuzona zonke, futhi okufanayo akunakushiwo ngezingxenye ze-elekthronikhi. I-Universal, kodwa isivele yephukile, futhi kungase kube kuhle ukuyithengisa endaweni ongayiqonda uma unemibandela.
