I-snowman ye-LED yawo wonke umuntu

Kunzima ukucabanga ubusika bungekho iqhwa. Futhi kunzima nakakhulu - ngaphandle kwe-snowman. Ngakho-ke, ngenkathi sisalinde iqhwa elengeziwe, siphakamisa ukwenza i-Snowman ngama-LED.

Ukudweba i-snowman kuwuphawu lobusika, kodwa kwabaningi bethu kuhlotshaniswa namaholide azayo, imibuthano yomndeni kanye nokuhlobisa isihlahla sikaKhisimusi, lapho ungalenga khona igajethi enikelwe njengenye yemihlobiso. Kungaba futhi isipho esihle enganeni esifuna ukuyigxilisa "isiphazamisi se-elekthronikhi". I-snowman eyethulwe inokubukeka okuhle, ngakho-ke uzoyithanda nakanjani.

Ukungabi bikho kwanoma iyiphi isekethe ehlanganisiwe kwenza ikhithi ethulwe ilungele onjiniyela abasaqalayo be-electronics. Kodwa-ke, akukho lutho oluvimbela abadala ukuthi baqoqe i-snowman enhle, ene-caricature, bayibheka njengokuzijabulisa ngesikhathi sabo samahhala emsebenzini wansuku zonke.

Incazelo yesakhiwo

Umdwebo wesifunda olula kancane ungatholakala kokuthi umfanekiso 1. Iqukethe kuphela uchungechunge lwama-LED amane akhanyayo axhunywe ngokuhambisana, lapho kuxhunywe khona umthombo wamandla ngendlela yamabhethri amabili angu-1,5V.

1. Umdwebo wohlelo lwe-snowman ye-LED

Ukuze kupheleliswe ukusebenza, kukhona iswishi SW1 kusekethe yamandla. I-LED ecwayizayo, ngaphezu komklamo wokukhanyisa, inohlelo lokulawula oluncane olwakhelwe ngaphakathi, ngakho-ke ingakwazi (futhi kufanele) inikwe amandla ngokuqondile, idlule isiphikisa esibeka umkhawulo wamanje. Ama-LED akhanyayo angabonwa ngendawo emnyama ngaphakathi kwekesi, ebonakala ngokucacile kuyo isithombe 1. Ngenxa yokungafani okuphawulekayo kumingcele yangaphakathi yamajeneretha alawa ma-LED, ngayinye yazo izokhanyisa ngefrikhwensi ehlukile, ehlukile. Le mvamisa iku-1,5-3 Hz futhi incike kakhulu ku-voltage yokuhlinzeka. I-LED1 ibomvu futhi ilingisa ikhala "lekherothi" lomuntu weqhwa, kulesi simo i-cartoonish kancane. Esikhundleni sezinkinobho ezimnyama "zamalahle" esiswini - ama-LED amathathu aluhlaza 2 ... 4.

Ukufakwa nokulungiswa

Isampula ye-PCB ifakiwe umfanekiso 2. Akudingi amakhono akhethekile ukuyihlanganisa.

Umsebenzi kufanele uqale ngokufaka i-soldering switch SW1. Idizayinelwe i-surface mounting (SMD) kodwa lokhu akumele kube yinkinga nakulabo abasanda kuthola izinto zikagesi.

Ukuze wenze izinto zibe lula, faka ithonsi lethani kwelinye lamaphuzu ayisithupha e-solder e-SW1, bese usebenzisa ama-tweezers ukubeka inkinobho endaweni elungiselelwe yona futhi uncibilikise isolder esetshenziswe ngaphambilini nge-solder iron. Iswishi elungiselelwe ngale ndlela ngeke inyakaze, ikuvumela ukuthi udayise kalula eminye imikhondo yayo.

Isinyathelo esilandelayo ekuhlanganiseni ukuhlanganisa ama-LED. Ebhodini elisuka ohlangothini lwe-soldering kukhona i-contour yabo - kufanele ihambisane ne-cutout ku-diode efakwe emigodini yokufaka.

Ukwengeza iqiniso kumlingiswa wethu "weqhwa", kufanelekile ukumenzela umshanelo, ongaxhunywa kahle kusuka epuleti lesiliva elifakwe kukhithi futhi lithengiswe kwelinye lamasimu okuthakwe emaphethelweni ebhodi lesifunda eliphrintiwe. . Inguqulo eyodwa yomshanelo nendawo yawo epuletini ivuliwe isithombe 2.

Njengocezu lokugcina, namathisela ubhasikidi webhethri nge-adhesive tape phansi, bese uthengisa ucingo olubomvu ensimini ye-BAT+ kanye nocingo olumnyama ensimini ye-BAT-, ulwenze lube mfushane ubude obudingekayo ukuze lungaphumeleli ngaphesheya uhlaka lweqhwa lethu. Manje - ukukhumbula i-polarity, ebhalwe kubhasikidi webhethri - sibeka amaseli amabili we-AAA (R03), okuthiwa. iminwe emincane.

Ukubukeka kweqhwa elihlangene limelela isithombe 3. Uma sihambisa iswishi ngasekhanda lethoyizi lethu, ama-LED azokhanya. Uma umfanekiso ohlanganisiwe unomkhuba wokuwa, izingcezu ezimfushane ze-silverware zingadayiswa ezindaweni ze-solder esisekelweni sazo ukuze zisebenze njengezisekelo.

Ukwenza kube lula ukulenga i-snowman, kukhona imbobo encane ku-cylinder yokufaka ucingo noma intambo.

Siphinde sincome ividiyo yokufundisa .
