Qhov no yog ib qib zuj zus qhia qhia yuav ua li cas thiaj pom kaum ob lub LED nyob hauv cov qauv sib txawv siv tsuas yog ob lub zog (Pots). Nws yog txoj haujlwm yooj yim heev thiab siv nyiaj txiag uas tsis tas yuav muaj kev txawj tshwj xeeb (tshwj tsis yog qee qhov kev siv tshuaj yaj yeeb) tab sis tsuas yog paub me ntsis txog cov khoom siv hluav taws xob.

Kauj ruam 1: Yuav tsum tau ua

Cov ntaub ntawv xav tau:

1. 12 x 5mm coj tus (xaiv ntau xim)
2. 4 x 100 ohm tsis kam
3. 4 x 33 kilo-ohm tsis kam
4. 4 x BC 548 transistor (lossis ib lub hom phiaj dav dav NPN transistor)
5. 4 x 22uf electrolytic capacitors
6. 2 x 250k kub
7. 1x9v Roj teeb
8. 1 x roj teeb clip
9. 1 x On/Off hloov
10. 1 x Lub hom phiaj dav dav PCB Board
11. Ob peb tus neeg dhia dhia (txhawm rau cuam tshuam nrog kev sib tshuam hauv Circuit)

TOOLS YUAV TSUM:

1. Soldering Hlau
2. Soldering Hlau
3. hlau txiav

Kauj Ruam 2: Kev tsim kho

Rau kev ua ntawm Bread Board

1. Teem tag nrho cov khoom siv raws li qhia hauv daim duab kab hluav taws xob.
2. Ua qhov sib txuas kom haum.

Nco tseg: Kuv tau ua kom yooj yim kev sib txuas rau coj hauv daim ntawv ntawm lub vaj huam sib luag. Yog li ntawd yog tias lub vaj huam sib luag tau ua cais ntawm pcb ces koj tuaj yeem yooj yim ua qhov Circuit Court no ntawm lub rooj mov ci. Properly kawm cov duab teeb tsa thiab ntawm Lub Hom Phiaj PCB:

1. Muab cov khoom tso rau ntawm qhov chaw tsim nyog.
2. Muab cov khoom sib dhos tso rau ntawm lawv qhov chaw.
3. Soj qab ua tib zoo saib cov kab kev sib txuas ua ke thiab tom qab ntawd ua cov laug. (lossis koj tseem tuaj yeem siv cov xov hluav taws xob hloov chaw ua cov kab laug sab, yooj yim me ntsis rau cov neeg uas tsis muaj tes zoo heev ntawm cov laug).
4. Txuas Lub Roj Teeb ntawm cov chaw tsim nyog thiab pom txoj haujlwm ua haujlwm.

Nco tseg: Koj tuaj yeem ua ntau hom sib txawv ntawm cov vaj huam sib luag coj raws li qhov muab rau hauv Circuit Court thiab tom qab ntawd txuas nws mus rau hauv Circuit Court uas siv cov hlua xaim. Qhov no kuj tseem pab tau yog tias ob peb tus coj nres kev ua haujlwm ces koj tuaj yeem siv cov vaj huam sib luag sib txawv yog tias twb tau ua lawm.

Kauj Ruam 3: Qhov No Ua Haujlwm Li Cas?

UA HAUJ LWM Kev ua haujlwm ntawm lub Circuit Court no yog ua raws ob lub astiv multivibrators uas zoo. Ib tus multivibrator tau tsim los ntawm transistor T1 & T2 thaum lwm tus yog tsim los ntawm T3 & T4. Lub voj voog ua haujlwm tuaj yeem sib txawv los ntawm kev hloov RC lub sijhawm tas li, uas tuaj yeem ua tiav los ntawm ob lub lauj kaub thiab cov qauv sib txawv LED tuaj yeem tsim tawm. Astiv multivibrator astable yog kev rov tsim hluav taws xob suav nrog ob theem ua kom zoo txuas nrog hauv cov lus tawm tswv yim zoo los ntawm ob lub peev xwm-tiv taus kev sib txuas ua ke. Cov transistors ua raws li cov ntsiab lus nthuav dav. Lub voj voog feem ntau yog kos rau hauv daim ntawv sib thooj raws li tus ntoo khaub lig-txuas ua ke. Ob lub davhlau ya nyob twg tuaj yeem txhais tau ntawm cov khoom siv nquag, uas yuav muaj lub xeev dawb; ib qho yuav muaj hluav taws xob siab thaum lwm tus muaj qhov hluav taws xob tsawg. Lub Circuit Court tau siv los ntawm kev sib txuas lub tshuab hluav taws xob uas hloov pauv qhov hloov pauv tam sim vim tias qhov hluav taws xob hla lub capacitor tsis tuaj yeem hloov pauv tam sim. Yog li ntawd, hauv txhua lub xeev ib lub transistor yog ON thiab lwm qhov yog OFF, yog li tsim cov txiaj ntsig xav tau los tsim cov qauv xav tau thiab ua rau kev ua haujlwm hauv Circuit Court.

Kauj ruam 4: PCB Version

Kuv kuj tau ua PCB version ntawm txoj haujlwm no. Hauv qhov no kuv siv coj ntawm peb xim sib txawv. PCB kev teeb tsa kev teeb tsa tau txuas nrog thiab cov txheej txheem teeb tsa zoo ib yam li cov duab hauv cov kauj ruam dhau los.
