Indlela yokuvula i-LED?

Indlela yokuvula i-LED? Ukuvula i-LED kungaba umsebenzi olula nojabulisayo uma wazi izinyathelo ezifanele. Ama-LED, noma ama-light-emitting diode, amathuluzi amancane akhipha ukukhanya lapho kusetshenziswa umsinga kagesi. Ukuze unike amandla i-LED, uzodinga i-LED ngokwayo, isixhasi, nomthombo wamandla, njengebhethri. Ngokulandela lezi zinyathelo ezilula, uzokwazi ukukhanyisa i-LED futhi uzame ukukhanya ngendlela ejabulisayo. Funda ukuze uthole ukuthi kanjani!

- Isinyathelo ngesinyathelo ➡️ Ukhanyisa kanjani i-LED?

• Ngoba vula i-LEDUzodinga izinto ezilandelayo:
• - I-LED (i-Light Emitting Diode)
• - Ukumelana phakathi kuka-220 no-1k ohms
• – Ibhodi lezinkwa noma i-breadboard
• – Izintambo zesilisa noma zesilisa
• - Ibhodi le-Arduino (uyazikhethela)
• Isinyathelo 1: Xhuma i-resistor ku-LED:
• Xhuma ingxenye eyodwa yesiphikisayo kuphinikhodi (i-anode) ye-LED. Ungakwazi ukubona i-anode ye-LED ngokuba umlenze omude kunayo yonke.
• Isinyathelo 2: Xhuma enye ingxenye yesinqamuleli kuphinikhodi (i-cathode) ye-LED. Ungakwazi ukubona i-cathode ye-LED ngokuba nomlenze omfushane noma ube nesicaba phezulu.
• Isinyathelo 3: Xhuma iphinikhodi ephozithivu (i-anode) ye-LED komunye wemigqa yamandla ebhodini lezinkwa noma ebhodini lezinkwa.
• Isinyathelo 4: Xhuma iphinikhodi (i-cathode) ye-LED komunye wemigqa ephansi yebhodi lezinkwa noma i-breadboard.
• Isinyathelo 5: Xhuma i-breadboard noma i-breadboard ebhodini le-Arduino:
• Uma usebenzisa ibhodi le-Arduino, xhuma intambo esuka kumugqa wamandla webhodi lezinkwa ukuya ephinikhodi engu-5V ebhodini le-Arduino.
• Xhuma enye intambo kusukela kumugqa ophansi webhodi lezinkwa ukuya ephinikhodi ye-GND yebhodi le-Arduino.
• Isinyathelo 6: Layisha ikhodi ebhodini le-Arduino (uma uthanda):
• Uma usebenzisa ibhodi le-Arduino, ungalayisha ikhodi ezovula futhi ivale i-LED ngokuzenzakalelayo.
• Isinyathelo 7: Vula i-LED:
• Uma usebenzisa ibhodi le-Arduino, shintsha ukucushwa kwephinikhodi okusetshenziswe kukhodi ukuze ithumele isignali yamandla ku-LED.
• Isinyathelo 8: Ilungile! I-LED kufanele manje ikhanyise.

Imibuzo Nezimpendulo

Indlela yokuvula i-LED?

1. Qoqa izinto ezidingekayo:
   • I-LED eyodwa (I-Light-Emitting Diode)
   • I-resistor efanelekile ye-LED
   • Umthombo wamandla (ibhethri noma ibhethri)
   • Izintambo zokuxhuma
2. Khomba amatheminali e-LED:
   • Itheminali ende kunazo zonke i-anode (+)
   • Itheminali emfushane kakhulu yi-cathode (-)
3. Xhuma i-resistor ku-cathode (-) ye-LED
4. Xhuma i-anode (+) ye-LED esigxotsheni esiqondile sokuphakelwa kwamandla
5. Xhuma isigxobo esinegethivu sikagesi ku-cathode (-) ye-LED (nge-resistor)
6. Ilungile! I-LED kufanele ivule
7. Khumbula: Uma uthola amandla okukhanya aphansi kakhulu noma i-LED ingakhanyi, hlola ukuthi isixhasi silinganiswe ngendlela efanele ukuze uqinisekise ukusebenza kahle kwe-LED.

Wazi kanjani ukuthi iyiphi i-resistor ongayisebenzisa ku-LED?

1. Ihlonza i-voltage yokusebenza (Vf) ye-LED
2. Yazi inani eliphezulu lamanje (Uma) elingageleza ku-LED ngaphandle kokulilimaza
3. Bala ukumelana usebenzisa umthetho we-Ohm:
   • Ukumelana (R) = (I-voltage yokunikezela (V) – I-LED yokusebenza kwamandla kagesi (Vf)) / Ubuningi bamanje (Uma)
4. Khetha ukumelana nokuhweba okuseduze nenani elibaliwe

Uyini umsebenzi we-resistor kusekethe ene-LED?
