Nyob zoo phooj ywg, Hnub no kuv yuav ua lub voj voog ntawm Lub Plawv Suab Nkauj rov ua lub teeb uas thaum lub suab paj nruag yuav ua si nyob ib puag ncig ntawm no ces LEDs yuav ci ci li suab paj nruag.
Cia peb pib,
Kauj Ruam 1: Nqa Txhua Cheeb Tsam Raws Li Qhia Hauv Qab
Cheebtsam yuav tsum tau -
(1.) Transistor - NPN (2N222) x1
(2.) LED - 3V (Txhua xim) x {Raws li LEDs xav tau los ua lub siab. Nws yuav nyob ntawm qhov loj ntawm lub plawv}
(3) Mic x1
(4.) Resistor - 33K x1
(5.) Roj teeb - 9V x1
(6.) Clipper roj teeb
Kauj Ruam 2: Ua Lub Plawv ntawm LEDs
Ua ntej peb yuav tsum ua Lub Plawv ntawm LEDs zoo li koj tuaj yeem pom hauv daim duab.
NCO TSEG: Cov ceg ntawm LEDs sib txuas ua ke (Kev sib txuas yuav +ve ntawm txhua lub LEDs rau ib leeg thiab -ve ntawm txhua ceg ntawm LEDs rau ib leeg).
~ Siv Cardboard los ua Lub Plawv ntawm LEDs.
Kauj Ruam 3: Txuas Transistor - 2N222
Tom ntej no peb yuav tsum txuas lub transistor mus rau Lub Plawv ntawm LEDs.
Solder Collector tus pin ntawm Transistor rau -ve tus pin ntawm LEDs raws li koj tuaj yeem pom hauv daim duab.
Kauj Ruam 4: Txuas 33K Resistor
Tom ntej no peb yuav tsum txuas 33K resistor rau hauv Circuit Court.
Solder 33K Resistor nruab nrab ntawm tus pin pin ntawm transistor rau +ve ceg ntawm LEDs li cov laug hauv daim duab.
Kauj Ruam 5: Txuas MIC
Tom ntej Txuas cov xov hlau ntawm MIC.
Solder +ve hlau ntawm mic rau Base pin ntawm transistor thiab
solder -ve xaim ntawm Mic rau emmiter tus pin ntawm transistor zoo li koj tuaj yeem pom hauv daim duab.
Kauj Ruam 6: Txuas Cov Roj Teeb Clipper Hlau
Tom ntej no peb yuav tsum txuas lub roj teeb clipper hlau rau hauv Circuit Court.
Solder +ve hlau ntawm lub roj teeb clipper rau +ve ob txhais ceg ntawm LEDs thiab
Solder -ve xaim ntawm lub roj teeb clipper rau Emmiter tus pin ntawm lub transistor raws li solder hauv daim duab.
Kauj Ruam 7: Yuav Siv Li Cas
Lub Plawv Lub Plawv Suab Nkauj reactive lub teeb hluav taws xob tau npaj tiav.
Txhawm rau siv qhov kev sib txuas no txuas 4V Roj Teeb rau Circuit thiab hais qee yam/ua suab paj nruag.
Raws li cov nkauj yuav muab lub suab zoo li ntawd LEDs yuav ci.
NCO TSEG: Peb tuaj yeem muab Cov Khoom Siv Hluav Taws Xob (4-6) V DC. Ntawm no kuv siv 9V Roj teeb rau lub hom phiaj ua piv txwv. Thov koj tsis txhob siv 9V Vim tias transistor tuaj yeem ua puas.
