te mata whakaatu i roto i te whakaaturanga riihi atamira

He aha te take i pango katoa ai te mata LED?
I roto i te whakamahi i te punaha whakahaere, i etahi wa ka tutaki tatou ki te ahuatanga he pango te mata LED.Ko taua ahuatanga ka puta mai i te maha o nga take rereke, tae noa ki te mahi pango o te mata ka rereke mai i te mahi ki te mahi, mai i te taiao ki te taiao.Hei tauira, ka mangu tonu inaa ana te hiko, ka mangu i te wa e utaina ana, ka mangu ranei i muri i te tukunga, aha atu:
1. Me mohio kua whakahikohia nga taputapu katoa tae atu ki te punaha whakahaere.(+5, kaua e whakamuri, e he ranei)
2. Tirohia me te whakapumau ano me te mea kua wetekina, kua taka ranei te taura rangatū hei hono i te kaiwhakahaere.
3. Tirohia me te whakaū mena kei te hono te mata LED me te papa tohatoha HUB e hono ana ki te kaari whakahaere matua ka whakauruhia ki muri.
2. He aha te take o te raina kanapa mo etahi hēkona i te wa e whakahikohia ana te mata whakaatu LED, ka pouri ranei te pikitia o te mata?
I muri i te hono tika o te kaiwhakahaere mata ki te rorohiko, te poari tohatoha HUB me te mata, he mea tika ki te whakarato i te mana + 5V ki te kaiwhakahaere kia pai ai te mahi (i tenei wa, kaua e hono tika ki te ngaohiko 220V).Ka puta he raina kanapa, he "mata pouri" ranei mo etahi hēkona, he ahuatanga whakamatautau noa, e whakamahara ana ki te kaiwhakamahi kua tata tuwhera te mata me te mahi noa.I roto i te 2 hēkona, ka whakakorehia te ahuatanga, ka uru te mata ki te ahua mahi noa.
3. Ko te take i kore ai te mata katoa o te papa wae i te kanapa me te atarua
1. Tirotiro titiro mehemea he tika te taura hononga hiko, te taura 26P i waenga i nga papa wae me te rama tohu tohu hiko.
2. Whakamahia he mita maha ki te whakamatautau mena he ngaohiko noa te papa wae o roto, katahi ka whakamatau mena he mea noa te putanga ngaohiko o te kōwae hiko o roto.Mena kaore, ka whakatauhia he kino te waahanga hiko.
3. I te wa e iti ana te ngaohiko o te waahanga hiko, whakatikahia te pai o te whakatikatika (te whakatikatika pai o te waahanga hiko e tata ana ki te rama tohu) kia eke te ngaohiko ki te paerewa.
4. He aha te take mo te kore e utaina, e korero ranei?
He rite tonu nga take mo te kore korero me te kore o te utaina, na enei take e whai ake nei.Whakatauritea nga mea kua whakarārangihia me te mahi:
1. Me mohio kei te tika te hiko o te punaha whakahaere.
2. Tirohia me te whakaū ko te taura rangatū i whakamahia hei hono i te kaiwhakahaere he taura torotika, ehara i te taura whakawhiti.
3. Tirohia me te whakaū kei te mau tonu te taura tauranga rangatū, karekau nga pito e rua e wetekina, e taka ranei.
4. Tīpakohia te tauira hua tika, te tikanga tuku tika, te tau tauranga rangatū tika, te reiti tuku rangatū tika kia rite ki te raupaparorohiko whakahaere whakaatu LED me te kaari mana e whiriwhiria e koe, ka tautuhi tika kia rite ki te hoahoa whakahuri DIP e whakaratohia ana i roto i nga Mana rorohiko nga moka wahitau me te tere whakawhiti rangatū i runga i te taputapu punaha.
5. Tirohia mehemea kua wetekina, kua taka ranei te potae pekepeke;ki te kore te potae pekepeke e wetekina, kia tika te ahunga o te potae pekepeke.
6. Ki te kore tonu e utaina i muri i te tirotiro me te whakatikatika i runga ake nei, tena koa whakamahi i te multimeter hei tirotiro mena kua pakaru te tauranga rangatū o te rorohiko hono, te taputapu punaha whakahaere ranei, hei whakapumau mehemea me whakahoki atu ki te kaihanga rorohiko, ki te mana whakahaere ranei. pūnaha.Tirohanga hokinga taputapu.
