Isibonisi se-LED singenye yemikhiqizo ye-elekthronikhi ethandwa kakhulu, kodwa kungakhathaliseki ukuthi yimuphi umkhiqizo osetshenziswayo, kuzoba nokwehluleka okuhlukahlukene. Kuthiwani uma kubiza ukucela othile ukuthi ayilungise? Silapha ukuzokwethula izinkinga nezisombululo ezivamile.
Okokuqala, isikrini sonke asikhanyi (isikrini esimnyama).
1. Hlola ukuthi ugesi unamandla yini.
2. Hlola ukuthi ikhebula lesiginali nekhebula le-USB kuxhunyiwe yini nokuthi ixhumeke ngokungalungile yini.
3. Hlola ukuthi ukukhanya okuluhlaza phakathi kwekhadi elithumelayo nokucwayiza kwekhadi elamukelayo.
4. Ukuthi isibonisi sekhompyutha sivikelekile, noma indawo eboniswa yikhompyutha imnyama noma iluhlaza okwesibhakabhaka.
Okwesibili, yonke imojula ye-LED ayikhanyi.
1. Ukuqondisa okuvundlile kwamamojula amaningana e-LED akukhanyi, hlola ukuthi uxhumano lwekhebula phakathi kwemojula ye-LED evamile kanye nemodyuli ye-LED engavamile kuxhunyiwe, noma ukuthi i-chip 245 ijwayelekile yini.
2. Ukuqondisa okuqondile kwamamojula amaningana e-LED akukhanyi, hlola ukuthi amandla ale kholomu ajwayelekile yini.
Ezintathu, imigqa eminingana ephezulu ye-module ye-LED ayikhanyi
1. Hlola ukuthi iphinikhodi yolayini ixhunyiwe yini kuphini lokuphumayo le-4953.
2. Hlola ukuthi i-138 ijwayelekile yini.
3. Hlola ukuthi i-4953 iyashisa noma ishile.
4. Hlola ukuthi i-4953 inezinga eliphezulu yini.
5. Hlola ukuthi izikhonkwane zokulawula 138 kanye ne-4953 zixhunyiwe yini.
Okwesine, imojula ye-LED ayinawo umbala
Hlola ukuthi idatha ye-245RG inokukhiphayo yini.
Okwesihlanu, ingxenye engaphezulu eyingxenye noma ingxenye ephansi ephansi yemojuli ye-LED ayikhanyi noma ayibonisi ngendlela engavamile.
1. Ukuthi kukhona isignali ye-OE emlenzeni wesi-5 we-138.
2. Ukuthi amasignali emilenze ye-11 kanye neye-12 ye-74HC595 ajwayelekile; (SCLK, RCK).
3. Ukuthi isignali ye-OE exhunyiwe ijwayelekile yini; (i-open circuit noma i-short circuit).
4. Ukuthi i-SCLK ne-RCK yamaphini wemigqa emibili exhunywe ku-245 ijwayelekile yini; (i-open circuit noma i-short circuit).
Isixazululo:
1. Xhuma isignali ye-OE ku
2. Xhuma amasignali e-SCLK kanye ne-RCK kahle
3. Xhuma isekethe evuliwe bese unqamula isekethe emfushane
4. Xhuma isekethe evuliwe bese unqamula isekethe emfushane
Isithupha, umugqa kumojula ye-LED noma umugqa wemojuli ehambisanayo awukhanyi noma uboniswa ngendlela engavamile.
1. Hlola ukuthi izikhonkwane zesignali yomugqa wemodyuli ehambisanayo zidayisiwe yini noma zigejiwe.
2. Hlola ukuthi ingabe iphinikhodi ehambisanayo yesiginali yomugqa kanye ne-4953 inqanyuliwe noma ifinyeziwe yini namanye amasignali.
3. Hlola ukuthi izinqamuleli ezingaphezulu naphansi zesiginali azithengiswanga noma azikho ukusoda.
4. Ukuthi ukukhishwa kwesiginali yomugqa ngo-74HC138 kanye ne-4953 ehambisanayo kunqanyuliwe noma kufinyezwa yi-circuited namanye amasignali.
Isixazululo sokwehluleka:
1. Solder i-welding engekho futhi engekho
2. Xhuma isekethe evuliwe bese unqamula isekethe emfushane
3. Gcwalisa izinto ezingadayisi bese ushisela ezilahlekile.
