Ungawaxhuma kanjani amalambu angaphandle komgwaqo ngaphandle kwe-relay (umhlahlandlela wezinyathelo ezingu-9)
Uma usebenzisa ama-relay ukuze uxhume izibani zomgwaqo, izinhlansi zingenzeka lapho amaleveli kagesi kanye namanje ephakeme kunalokho okudingekayo. Ngemva kokuvula i-relay, izinhlansi zingabonakala. Futhi, i-relay inesikhathi sokuphendula esihamba kancane, esingase sibe yinkinga, ngakho-ke kungcono ukuxhuma izibani zomgwaqo ngaphandle kwe-relay. Kodwa-ke, abantu abaningi bayazabalaza ngendlela yokucisha izibani zomgwaqo ngaphandle kokudluliswa kwemali.
Uma ufuna ukufunda ngokuningiliziwe ukuthi ungaxhuma kanjani izibani ezingaphandle komgwaqo ngaphandle kwe-relay, funda lesi sihloko futhi uzokwazi ukuxhuma ngokushesha izibani zakho.
Ixhuma izibani zangaphandle komgwaqo ngaphandle kokudluliswa kwemali
Awukwazi ukuxhuma izibani ezingaphandle komgwaqo ngokuqondile ngaphandle kwe-relay. Ibhulokhi yesiguquli esilawula izinga le-voltage phansi nezigodlo liyadingeka ukuze kukhuliswe ukukhanya kwama-LED. Ama-LED akufanele neze asetshenziswe kumaza aphezulu njengoba lokhu kungadala ukushisa nezintambo ezincibilikisa. Kungcono ukuwasebenzisa ku-voltage ephansi ukuze angashisi ngokweqile. Landela lo mhlahlandlela wezinyathelo eziyi-9 ukuze ufake amalambu angekho emgwaqeni ngezintambo ngaphandle kokudluliswa kwezintambo:
1. Indawo engcono kakhulu
Khetha indawo ekahle yokukhweza isibani sakho esingekho emgwaqeni. Indawo ekahle ivumela izintambo nokukhanyisa. Uma ungenayo le ndawo, kuzomele wenze othayi be-zip noma izikulufu. Yenza ubuciko ngalesi sigaba, njengoba indawo enhle yokufaka izohamba ibanga elide.
2. Geza imbobo
Uma usukhethe indawo engcono kakhulu yezibani zakho ezingekho emgwaqeni, mba izimbobo ezinosayizi olungile endaweni efanele. Maka indawo ngaphambi kokubhoboza. Ngale ndlela uyazi ukuthi ubhola endaweni efanele. Qaphela ukuthi ungashayi lutho olungalimaza.
3. Faka amabakaki amalambu angekho emgwaqeni.
Ngemuva kokuthi usuqedile ukubhola, ungafaka amabakaki alula. Qiniseka ukuthi unazo zonke izikulufu ezidingekayo. Ivikele ngezikulufo ezifakiwe. Ungenza izinguquko futhi uziguqule ngendlela ofisa ngayo. Nokho, ungayiqinisi kakhulu, njengoba uzodinga ukuyishintsha kamuva.
4. Nqamula izintambo ebhethrini.
Manje kufanele uthole uhlangothi lwamandla ebhethri. Nqamula ikhebula ebhethrini lemoto ngaphambi kokufaka iswishi. Lokhu ngeke kwenziwe ngenkathi ibhethri isebenza njengoba kungase kubangele ukushaqeka kukagesi. Kufanele uqinisekise ukuthi akukho kulimala phakathi nenqubo. (1)
5. Thola umthombo wamandla ongcono kakhulu
Uma usulivikele ibhethri lemoto yakho, yisikhathi sokunquma ukuthi uzonamathisela kuphi iswishi. Iswishi kufanele ifakwe endaweni okufinyeleleka kalula kuyo. Uma usunqume ukuthi inkinobho kufanele iye kuphi, yisikhathi sokuyixhuma kumthombo wamandla. Kumelwe uqinisekise ukuthi ukunikezwa kwamandla kungakwazi ukuphatha i-voltage efanayo namandla njengamalambu akho angaphandle komgwaqo.
6. Xhuma iswishi emthonjeni wamandla.
Kuyinto efiselekayo ukuba nenqubo yokufaka esheshayo nephumelelayo; ukuze ukwazi ukusebenzisa iswishi yesilawuli kude. Xhuma iswishi emthonjeni wamandla uma usunqume ukunikezwa kwamandla okuhle kakhulu kwezinto zakho. Khetha i-resistor engakwazi ukuphatha inani eliphezulu lamanje eligeleza kuyo. Uma ungenzi kanjalo, maningi amathuba okuthi kuzolimaza imicu yakho yokukhanya. Ngaphambi kokukhetha i-resistor elungile, yenza izibalo ezithile ze-voltage nezamanje kusekethe yakho yokulawula.
7. Faka iswishi
Uma usuthole i-resistor efanele, ungafaka iswishi. Qinisekisa ukuthi i-switch and control circuit ivaliwe ukuze ugweme amaphutha. Sebenzisa intambo yethusi ukuxhuma iswishi ne-resistor. Lapho uxhuma ucingo, beka iziphetho zombili endaweni efanele futhi uzidayise ndawonye. Bese uxhuma uhlangothi oluphambene lweswishi ekunikezeni amandla. (2)
8. Xhuma ugesi esibanini esingaphandle komgwaqo.
Kungcono ukuxhuma amandla kagesi kuma-lightbar angaphandle komgwaqo. Bese uxhuma izingxenye ezisele ngezinqwaba uma usuxhume zonke izingxenye. Xhuma itheminali yebhethri enegethivu kukhebuli esuka emotweni yakho. Bese, usuka emotweni yakho, uxhume enye intambo kutheminali yebhethri ephozithivu.
9. Hlola kabusha
Uma usuqedile izinyathelo zangaphambilini, uzodinga ukukhomba ilambu elingekho emgwaqeni elifakwe emotweni yakho ngendlela efanele. Bese uqinisa i-hardware efakiwe. Phinda uhlole yonke into uma usuxhume zonke izintambo futhi uzixhume ngendlela efanele. Ngakho-ke ungabona ukuthi ungawaxhuma kanjani amalambu angaphandle komgwaqo ngaphandle kokudluliswa kwemali kulezi zinyathelo. Landela le miyalo ngokuqondile futhi uqiniseke ukuthi awekho amaphutha. Uma usukwenzile lokho, izibani zemoto yakho zizobe sezilungile.
