Zolephera zambiri za chiwonetsero chamtundu wamtundu wa LED zimayamba chifukwa cha kuyika kolakwika.Choncho, masitepe ayenera mosamalitsa kutsatiridwa pa unsembe ndondomeko, makamaka pa unsembe woyamba.Kuti muchepetse kupezeka kwa zolakwika, tiyeni tiwone mawonekedwe amtundu wa LED.Chiwonetsero cha mawaya cha chinsalu chowonetsera ndi njira yolumikizira mawaya masitepe kuti muyike chiwonetsero chamtundu wa LED.

1. Chithunzi cholumikizira chingwe cha LED chamtundu wathunthu

Awiri, njira masitepe

1. Onani ngati voteji yamagetsi yamtundu wamtundu wa LED ndi yabwinobwino.

Pezani magetsi osinthika okhala ndi zolumikizira zabwino ndi zoyipa za DC, lumikizani chingwe chamagetsi cha 220V kumagetsi osinthira, (onetsetsani kuti alumikizidwa bwino, lumikizani AC kapena NL terminal), ndikulumikiza magetsi.Kenako gwiritsani ntchito ma multimeter ndi DC kuti muyeze voteji kuti muwonetsetse kuti voteji ili pakati pa 4.8V-5.1V, ndipo pambali pake pali knob, yomwe imatha kusinthidwa ndi screwdriver ya Phillips, ndipo mawonekedwe a DC amagwiritsidwa ntchito kuyeza Voteji.Pofuna kuchepetsa kutentha kwa chinsalu ndikutalikitsa moyo wake, magetsi amatha kusinthidwa kukhala 4.5V-4.8 kumene kufunikira kowala sikuli kwakukulu.Pambuyo potsimikizira kuti palibe vuto ndi magetsi, dulani magetsi ndikupitiriza kusonkhanitsa mbali zina.

2. Zimitsani mphamvu ya chiwonetsero chotsogolera chamitundu yonse.

Lumikizani V+ ku waya wofiyira, V+ ku waya wakuda, motsatana lumikizani khadi yoyang'anira chiwonetsero chamtundu wamtundu wa LED ndi gulu la LED, ndi waya wakuda ku khadi yowongolera ndi magetsi a GND.Red imalumikiza khadi yowongolera + 5V voteji ndi gulu la unit VCC.Bolo lililonse lili ndi waya.Mukamaliza, fufuzani kuti kulumikizana ndi kolondola.

3. Lumikizani chowongolera chowongolera chamitundu yonse ndi bolodi la unit.

Gwiritsani ntchito mawaya abwino ndi malumikizidwe.Chonde mverani komwe akulowera ndipo musasinthe kulumikizana.Bolodi yamtundu wamtundu wa LED ili ndi mawonekedwe awiri a 16PIN, 1 ndikulowetsa, 1 imatuluka, ndipo pafupi ndi 74HC245/244 ndikulowetsa, ndipo khadi yowongolera imalumikizidwa ndi zolowetsa.Zomwe zimatuluka zimagwirizanitsidwa ndi zolowetsa za gulu lotsatira la unit.

4. Lumikizani mzere wa data wa RS232 wa chiwonetsero chamtundu wa LED.

Lumikizani mbali imodzi ya chingwe chopangidwa ndi data ku doko la kompyuta la DB9, ndipo kumapeto kwina ku khadi lowongolera lamitundu yonse, lumikizani pini 5 (bulauni) ya DB9 ku GND ya khadi yowongolera, ndikulumikiza 3. pini (bulauni) ya DB9 ku ulamuliro RS232-RX wa khadi.Ngati PC yanu ilibe doko la siriyo, mutha kugula chingwe chosinthira cha USB kupita ku RS232 kuchokera ku Computer Store.

5. Yang'ananinso kulumikizidwa kwa chiwonetsero chotsogolera chamitundu yonse.

Kaya waya wakuda walumikizidwa molondola ndi -V ndi GND, ndipo waya wofiira walumikizidwa ku +V ndi VCC+5V.

6. Yatsani magetsi a 220V ndikutsegula mapulogalamu omwe adatsitsidwa ndi chiwonetsero chamtundu wa LED.

Nthawi zambiri, kuyatsa kwamagetsi kumayaka, khadi yowongolera imayatsidwa, ndipo chiwonetsero chamtundu wamtundu wa LED chikuwonetsa.Ngati china chake sichili bwino, chonde onani kulumikizana.Kapena fufuzani zovuta.Khazikitsani zowonera pazenera ndikutumiza mawu ang'onoang'ono.Chonde onani malangizo a mapulogalamu.
