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
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
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
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
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
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
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
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.
