Yawancin kasawa na nunin LED mai cikakken launi yana faruwa ta hanyar shigar da bai dace ba.Don haka, dole ne a bi matakan da suka dace yayin aikin shigarwa, musamman lokacin shigarwa na farko.Domin rage faruwar kurakurai, bari mu kalli LED mai cikakken launi.Zane-zane na allon nuni da matakan hanyar wayoyi don shigar da nunin LED mai cikakken launi.

1. Cikakken launi LED nuni na USB zane zane

Biyu, matakai na hanya

1. Bincika ko ƙarfin wutar lantarki na cikakken launi LED nuni ne na al'ada.

Nemo wutar lantarki mai sauyawa tare da haɗin kai na DC mai kyau da mara kyau, haɗa igiyar wutar lantarki 220V zuwa wutar lantarki mai sauyawa, (tabbatar da an haɗa shi daidai, haɗa tashar AC ko NL), kuma haɗa wutar lantarki.Sannan a yi amfani da yanayin multimeter da DC don auna wutar lantarki don tabbatar da cewa wutar lantarki tana tsakanin 4.8V-5.1V, kuma akwai kulli a gefensa, wanda na'urar screwdriver na Phillips za ta iya daidaita shi, kuma ana amfani da yanayin DC don auna wutar lantarki. ƙarfin lantarki.Domin rage zafin allon da kuma tsawaita rayuwarsa, ana iya daidaita wutar lantarki zuwa 4.5V-4.8 inda buƙatun haske ba ta da girma.Bayan tabbatar da cewa babu matsala tare da wutar lantarki, yanke wutar lantarki kuma ci gaba da harhada wasu sassa.

2. Kashe ikon nunin jagora mai cikakken launi.

Haɗa V+ zuwa wayar ja, V+ zuwa baƙar fata, bi da bi suna haɗa katin kula da nunin LED mai cikakken launi da panel ɗin LED, da baƙar waya zuwa katin sarrafawa da wutar lantarki ta GND.Red yana haɗa katin sarrafawa + 5V ƙarfin lantarki da kwamitin naúrar VCC.Kowane allo yana da waya.Idan kun gama, duba cewa haɗin daidai yake.

3. Haɗa mai kula da nunin jagora mai cikakken launi da allon naúrar.

Yi amfani da wayoyi masu kyau da haɗi.Da fatan za a kula da jagora kuma kada ku juya haɗin.Babban allon nunin jagorar mai cikakken launi yana da musaya na 16PIN guda biyu, 1 shigarwa ne, 1 yana fitarwa, kuma kusancin 74HC245/244 shine shigarwa, kuma an haɗa katin sarrafawa zuwa shigarwar.An haɗa fitarwa zuwa shigar da allon naúrar na gaba.

4. Haɗa layin bayanan RS232 na nunin LED mai cikakken launi.

Haɗa ƙarshen kebul ɗin bayanan da aka yi zuwa tashar DB9 na kwamfutar, ɗayan ƙarshen zuwa katin sarrafa jagorar cikakken launi, haɗa 5 pin (brown) na DB9 zuwa GND na katin sarrafawa, sannan haɗa 3 fil (launin ruwan kasa) na DB9 zuwa RS232-RX na katin.Idan PC ɗinka ba shi da tashar tashar jiragen ruwa, za ka iya siyan kebul na USB zuwa RS232 kebul na musanya tashar jiragen ruwa daga Shagon Kwamfuta.

5. Duba haɗin haɗin nunin jagora mai cikakken launi.

Ko baƙar waya ta haɗa daidai da -V da GND, kuma jajayen waya an haɗa shi zuwa + V da VCC+5V.

6. Kunna wutar lantarki na 220V kuma buɗe software da aka sauke ta cikakken nunin LED mai launi.

Yawancin lokaci, hasken wuta yana kunne, katin sarrafawa yana kunne, kuma cikakken nunin LED mai launi yana nuna shi.Idan wani abu ba daidai ba ne, da fatan za a duba haɗin.Ko duba matsala.Saita sigogin allo kuma aika rubutun kalmomi.Da fatan za a koma ga umarnin software.
