Yuav Ua Li Cas LED Flasher Circuit Siv BD139 Transistor
Yuav Ua Li Cas LED Flasher Circuit Siv BD139 Transistor

Nyob zoo phooj ywg, Hnub no kuv yuav ua ib qho Circuit Court ntawm LED Flasher siv BD139 Transistor.

Cia peb pib,

Kauj Ruam 1: Nqa Txhua Cheeb Tsam Raws Li Qhia Hauv Qab

Coj tag nrho cov Cheeb Tsam Raws Li Qhia Hauv Qab

Cheebtsam yuav tsum tau -

(1.) Transistor - BD139 x1

(2.) Capacitor - 25V 2200uf x1

(3.) Capacitor - 50V 4.7uf x1

(4.) Resistor - 1K x1

(5.) LED - 3V x1

(6.) Fais fab mov - 12V DC

Kauj Ruam 2: Daim duab Circuit Court

Daim duab Circuit Court
Daim duab Circuit Court

Nov yog daim duab qhia chaw ntawm txoj haujlwm no.

Txuas tag nrho cov khoom siv raws li daim duab qhia chaw no.

Kauj Ruam 3: Txuas 4.7uf Capacitor

Txuas 4.7uf Capacitor
Txuas 4.7uf Capacitor

Solder +ve tus pin ntawm tus capacitor rau Base tus pin ntawm transistor

thiab cov kab laug sab -v tus pin ntawm lub tshuab hluav taws xob rau emmiter tus pin ntawm lub transistor li cov laug hauv daim duab.

Kauj Ruam 4: Txuas 2200uf Capacitor

Txuas 2200uf Capacitor
Txuas 2200uf Capacitor

Tom ntej no peb yuav tsum tau txuas +tus pin ntawm 2200uf capacitor rau emmiter tus pin ntawm transistor zoo li koj tuaj yeem pom hauv daim duab.

Kauj Ruam 5: Txuas LED mus rau Circuit

Txuas LED mus rau Circuit
Txuas LED mus rau Circuit

Tom ntej no peb yuav tsum tau sib dhos +cov ceg ntawm LED rau Collector tus pin ntawm transistor thiab

solder -ve tus pin ntawm LED rau -ve ntawm 2200uf capacitor raws li koj tuaj yeem pom hauv daim duab.

Kauj Ruam 6: Txuas 1K Resistor

Txuas 1K Resistor
Txuas 1K Resistor

Tom ntej solder 1K resistor rau -ve tus pin ntawm 2200uf capacitor/-ve ceg ntawm LED li cov laug hauv daim duab.

Kauj Ruam 7: Txuas Cov Khoom Siv Hluav Taws Xob

Txuas Cov Khoom Siv Hluav Taws Xob
Txuas Cov Khoom Siv Hluav Taws Xob
Txuas Cov Khoom Siv Hluav Taws Xob
Txuas Cov Khoom Siv Hluav Taws Xob

Peb lub voj voog tiav.

Yog li tam sim no peb yuav tsum txuas cov tswv yim hluav taws xob xaim hluav taws xob rau hauv Circuit Court.

Txuas +ve clip rau Emmiter tus pin ntawm Transistor thiab

Txuas -ve clip rau 1K resistor raws li koj tuaj yeem pom hauv daim duab.

NCO TSEG: Peb yuav tsum muab 12V DC Input Power supply rau hauv Circuit no.

Tam sim no LED yuav flashing.
