Video: Yooj Yim Hmo Teeb Siv Cov Teeb Fairy: 3 Kauj Ruam (nrog Duab)
2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:29
Kuv siv los siv cov teeb hmo ntuj yooj yim, tab sis tom qab ntawd kuv muaj qee qhov teeb pom kev zoo nkauj, xav tias vim li cas ho tsis siv lawv ua hmo ntuj hloov?
Qhov no tseem tiv thaiv lub teeb los ntawm teeb kom cuam tshuam kev pw tsaug zog yog tias kuv puas tau sawv thaum hmo ntuj thiab qhov tseem ceeb tshaj plaws saib yog qhov xav tsis thoob.
Yog li txoj hlua ntawm lub teeb zoo nkauj no khiav ncaj hla kuv lub txaj mus rau kuv chav dej.
Kuv tau siv LDR yog li kuv tsis tas yuav siv qhov hloov pauv thiab lawv tau qhib thaum kuv tso kuv lub teeb teeb thaum hmo ntuj.
Kauj Ruam 1: Cheeb Tsam
1. Fairy Teeb
2. Variable Kuj
3.1K tiv thaiv
4. Lwd
5. Transistor 2n2222 lossis ksp2222 lossis lwm txoj hauv kev
6. 18650 roj teeb rau fais fab mov
7. Lub rooj mov ci
8. Jumper Wires
Kauj ruam 2: Circuit Court
Lub Circuit Court yog ib qho yooj yim li nws tuaj yeem ua tau.
Koj tuaj yeem siv resistor hauv koob nrog LEDs tab sis Cov khoom siv hluav taws xob yuav tsis ua rau nws puas tsuaj, yog li kuv tsis tau siv ib qho.
Qhov sib txawv resistor yog nyob ntawm yeem tab sis nws tuaj yeem siv tau thaum koj xav hloov qhov ci ntawm LED hlua.
Peb tuaj yeem siv P lossis N hom 2222 transistor, tus pin daim duab rau ob qho tib si tau qhia, koj tsuas yog yuav tsum tso cov thaiv kom raug saib xyuas qhov twg Emitter-Base-Collector pins ntawm transistor nyob ntawd.
Kauj Ruam 3: Kev Ua Haujlwm thiab Kev Sib Txuas
Ua ntej, Kuv txiav lossis tshem tawm cov xaim ntawm lub teeb pom kev zoo los ntawm lub roj teeb lub thawv nws los nrog raws li kuv yuav tsum tau siv nws thiab tag nrho cov Circuit Court cais nrog 18650 los ntawm kuv lub laptop txij li nws yooj yim dua 18650s thiab kuv ntxub siv nyiaj ntawm roj teeb yog li kuv xav 18650.
Cov xov hlau yog qhov yooj yim Lub Emitter tau txuas ncaj qha rau Qhov Zoo ntawm roj teeb.
Cov hlua LED txuas nrog nruab nrab ntawm qhov tsis zoo ntawm lub roj teeb thiab Tus Pin Collector ntawm lub transistor nrog qhov kawg ntawm LED txuas nrog Tus Sau thiab qhov tsis zoo kawg rau qhov tsis zoo ntawm roj teeb.
Tam sim no Lub hauv paus ib txwm txuas nrog lub roj teeb zoo tab sis dhau ntawm LDR thiab Kev hloov pauv tsis sib xws nyob nruab nrab.
Kev hloov pauv tsis sib xws thiab 1K ohm resistor khiav hauv Series, thiab LDR yog nyob rau hauv Parallel rau qhov Circuit Court no thiab tom qab ntawd txuas nrog Lub Hauv Paus, qhov no pab hloov qhov ci ci ntawm cov hlua LED zoo nkauj.
Thaum Circuit tau npaj txhij, Koj npaj txhij los Xeem.
Yaj.. !! Koj Hmo Hmo LED fairy hlua tau npaj lawm..
Txaus siab rau Saib.
