Umboniso we-LED yenye yeemveliso ze-elektroniki ezithandwa kakhulu, kodwa kungakhathaliseki ukuba yeyiphi imveliso esetyenziswayo, kuya kubakho ukusilela okwahlukeneyo. Kuthekani ukuba kuyabiza ukucela umntu ukuba ayilungise? Silapha ukuzazisa iingxaki eziqhelekileyo kunye nezisombululo.
Enye, isikrini sonke asiqaqambi (isikrini esimnyama).
1. Jonga ukuba unikezelo lombane luyasebenza na.
2. Jonga ukuba intambo yesignali kunye nentambo ye-USB iqhagamshelwe kwaye ingaba iqhagamshelwe ngokungalunganga.
3. Jonga ukuba ngaba ukukhanya okuluhlaza phakathi kwekhadi lokuthumela kunye nekhadi elifumanayo elidanyazayo.
4. Ingaba umboniso wekhompyutha ukhuselwe, okanye indawo yokubonisa ikhompyutha imnyama okanye iblue blue.
Isibini, yonke imodyuli ye-LED ayiqhakazi.
1. Ulwalathiso oluthe tye lweemodyuli ezininzi ze-LED alukhanyisi, khangela ukuba uxhulumaniso lwekhebula phakathi kwemodyuli ye-LED eqhelekileyo kunye nemodyuli ye-LED engaqhelekanga ixhunyiwe, okanye ukuba i-chip 245 iyinto eqhelekileyo.
2. Isalathiso esithe nkqo seemodyuli ezininzi ze-LED aziqhakazi, khangela ukuba unikezelo lwamandla lwale kholamu luqhelekileyo.
Ezintathu, imigca emininzi ephezulu yemodyuli ye-LED ayiqhakazi
1. Khangela ukuba i-pin pin ixhunyiwe kwi-4953 ye-output pin.
2. Jonga ukuba u-138 uqhelekile na.
3. Jonga ukuba i-4953 ishushu okanye itshile.
4. Khangela ukuba ngaba i-4953 inezinga eliphezulu.
5. Khangela ukuba izikhonkwane zokulawula i-138 kunye ne-4953 zixhunyiwe.
Okwesine, imodyuli ye-LED ayinambala
Jonga ukuba ingaba idatha ye-245RG inemveliso.
Isihlanu, isiqingatha esiphezulu senxalenye okanye isiqingatha esisezantsi semodyuli ye-LED ayiqaqambi okanye ibonise ngokungaqhelekanga.
1. Ingaba kukho uphawu lwe-OE kumlenze we-5 we-138.
2. Ingaba iimpawu zomlenze we-11 kunye nowe-12 we-74HC595 ziqhelekileyo; (SCLK, RCK).
3. Ingaba uphawu lwe-OE oludityanisiweyo luqhelekile; (isiphaluka esivulekileyo okanye isiphaluka esifutshane).
4. Ingaba i-SCLK kunye ne-RCK yeempawu ze-double-row pins ezixhunywe kwi-245 ziqhelekileyo; (isiphaluka esivulekileyo okanye isiphaluka esifutshane).
Isisombululo:
1. Qhagamshela uphawu lwe-OE ku
2. Xhuma i-SCLK kunye ne-RCK izibonakaliso kakuhle
3. Qhagamshela isekethe evulekileyo kwaye ukhuphe isekethe emfutshane
4. Qhagamshela isekethe evulekileyo kwaye ukhuphe isekethe emfutshane
Isithandathu, umqolo kwimodyuli ye-LED okanye umqolo wemodyuli ehambelanayo ayiqaqambi okanye iboniswe ngokungaqhelekanga.
1. Khangela ukuba izikhonkwane zomgca wemodyuli ehambelanayo zithengiswa okanye zilahlekile.
2. Khangela ukuba i-pin ehambelanayo yesignali yomgca kunye ne-4953 inqanyuliwe okanye ifutshane-ifutshane kunye nezinye iimpawu.
3. Khangela ukuba ngaba i-resitors ephezulu nasezantsi yesignali yomgca ayithengiswanga okanye ilahlekile.
4. Ingaba imveliso yesignali yomgca nge-74HC138 kunye ne-4953 ehambelanayo inqanyuliwe okanye ifutshane-ijikelezwe kunye nezinye iimpawu.
Isisombululo sokusilela:
1. Solder i-welding engekho kunye nelahlekileyo
2. Qhagamshela isekethe evulekileyo kwaye ukhuphe isekethe emfutshane
3. Gcwalisa izinto ezingathengiswanga kwaye udibanise ezilahlekileyo.
