Cov lus qhia no yog hais txog kev ua lub teeb nyem LED nrog lub teeb / tsaus nti. nws tig tau txais thaum nws tsaus ntuj thiab tua thaum nws hnub.
Kauj Ruam 1: Kauj Ruam 1: Sau Cov Khoom:
Nov yog yam koj yuav xav tau:
1. LDR (Lub Teeb Pom Kev Pom Zoo / Kev Ntsuas Tus Kheej) 2. NPN Transistor (Kuv tau siv BC 547) 3. 9 volt roj teeb 4. 9v lub roj teeb hau 5. Plaub LEDs, 5 hli ci dawb 6. 1/4 watt, 100 ohm resistor (ib LED, yog li 400-500 ohms rau 4-5 leds) 7. 1/4 watt, 10k ohm resistor (ib tus coj) 8. me me ntawm PCB los teeb tsa lub rooj sib txoos.
Nco tseg: Hloov cov khoom 6 & 7, koj tuaj yeem siv ib leeg 500 ohm & 50K (lossis 100k) resistor txhua, yog tias koj yuav siv tsuas yog 4 lossis 5 leds….
Cov cuab yeej ntxiv xws li, cov laug, kab hlau txuas, kua nplaum kub lossis nws qhov sib npaug.
Kauj Ruam 2: Kauj Ruam 2: Sib Sau Ua Ke
1. Mount plaub LEDs ntawm smail pcb nrog sab zoo sab nraud, raws li qhia. 2. Muab cov ceg zoo tso ua ke thiab ob txhais ceg tsis zoo ua ib qho (sib luag), raws li qhia. 3. Tam sim no, txuas qhov zoo ntawm 4 leds mus rau 100 ohm resistor. Txuas qhov xoob kawg ntawm qhov 100 ohm resistor rau 10k resistor. qhov xoob / qhov kawg ntawm 10k resistor yuav tsum txuas nrog rau nruab nrab ceg ntawm NPN Transistor. 4. Txuas qhov tsis zoo ntawm tus coj mus rau npn tus neeg khaws khoom (sab laug ntawm NPN transistor, nrog qhov sib npaug tig rau koj), raws li qhia 5. Tam sim no txuas LDR mus rau nruab nrab ceg thiab sab xis ntawm NPN. Tam sim no Txheeb: (Saib ob daim duab) Ob txoj hlua hlau ntawm qhov kev sib dhos zaum kawg yuav tsum tau siv los ua qhov zoo thiab qhov tsis zoo: - ib khub los ntawm ldr & sab xis ntawm npn, uas mus rau lub roj teeb tsis zoo (lossis xaim liab ntawm lub hau) - lwm yam los ntawm cov ceg zoo ntawm cov coj nrog nrog 100 ohm resistor. Qhov no yog qhov zoo thiab yuav tsum mus rau qhov zoo ntawm 9v roj teeb, dhau ntawm lub hau dub.
Kauj Ruam 3: Kauj Ruam 3: Cov txiaj ntsig
2 daim duab thiab video mpeg (Hauv qab no) ntawm tus qauv ua haujlwm.
Kauj Ruam 4: Kauj Ruam 4: Kev lees paub & Lub Tswv Yim
Kev lees paub: Kuv tau tshoov siab los ntawm ntau txoj haujlwm, suav nrog cov ntawd, raws li hauv qab no: Dipankaramando96 Lwm lub tswv yim: - koj tuaj yeem sim qhov no nrog lwm lub roj teeb - 3v, 6v, lossis 12v. - koj tuaj yeem ntxiv joule tub sab sib dhos rau nws. - Kuv npaj yuav ua cov lus qhia ntawm lub teeb pom kev zoo ntawm lub zog hluav taws xob, tom qab ntawd, tab sis lwm tus kuj tseem yuav sim, yog tias paub zoo! & Thaum kawg: Pov npav lossis tawm tswv yim, yog tias koj nyiam qhov project! regards kev
