Nyob zoo phooj ywg, Hnub no kuv yuav ua VU Meter Circuit siv tsuas yog ib qho transistor Hauv qhov VU Meter kuv yuav siv 2N2222A Transistor. Qhov VU Meter tsis zoo li piv rau 3915 IC VU Meter.
Cia peb tau hais,
Kauj Ruam 1: Nqa Txhua Cheeb Tsam Raws Li Qhia Hauv Qab
Cheebtsam yuav tsum tau -
(1.) Transistor - 2N2222A x1
(2.) LED - 3V x6 (Txhua xim)
(3.) Resistor - 1K x6
(4.) aux cable x1
(5.) Zero PCB
(6.) Roj teeb - 9V
(7.) Clipper roj teeb
Kauj Ruam 2: Transistor - 2N2222A
Qhov no yog qhov pinout ntawm tus transistor no.
Pin-1 yog Emmiter, Pin-2 yog Base thiab
Pin-3 ntawm tus transistor no yog Collector.
Kauj Ruam 3: Txuas Txhua LEDs
Muab tag nrho cov LEDs ntawm Xoom PCB thiab Solder nws ob txhais ceg ua ke.
Kauj Ruam 4: Txuas LEDs hauv Series
Solder +ve ceg ntawm ib qho LED rau -ve ceg ntawm lwm LED li cov laug hauv daim duab.
Kauj Ruam 5: Txuas 1K Resistors
Tom ntej no peb yuav tsum txuas 1K resistors rau +ve ob txhais ceg ntawm txhua lub LEDs zoo li koj tuaj yeem pom hauv daim duab.
Kauj Ruam 6: Txuas Lwm Sab Ntawm Cov Tiv Thaiv
Kuaj tag nrho cov xov hlau ntawm 1K Resistors rau ib leeg. {Txuas txhua tus pin ntawm lwm sab ntawm 1K Resistors} raws li koj tuaj yeem pom hauv daim duab.
Kauj Ruam 7: Muab Transistor
Tom ntej no peb yuav tsum txuas lub transistor mus rau PCB.
Txuas Tus Ntaus Tus pin ntawm transistor rau -ve ob txhais ceg ntawm txhua lub LEDs li cov laug hauv daim duab.
Kauj Ruam 8: Txuas Aux Cable Hlau
Tom ntej no peb yuav tsum txuas aux cable xaim rau hauv Circuit Court.
Solder +ve hlau {Sab laug/Txoj Cai} ntawm lub xov tooj cua txuas mus rau Lub hauv paus Pin ntawm Transistor thiab
Txuas -v xaim {GND} ntawm cov kab txuas rau emmiter tus pin ntawm transistor.
Kauj Ruam 9: Txuas Cov Roj Teeb Clipper Hlau
Tam sim no peb yuav tsum txuas lub roj teeb clipper rau hauv Circuit Court.
Txuas +ve hlau ntawm lub roj teeb clipper rau Tawm {Lwm sab ntawm 1K Resistor} Sab ntawm 1K Resistor thiab
-ve xaim ntawm lub roj teeb clipper rau Emmiter tus pin ntawm lub transistor raws li koj tuaj yeem pom hauv daim duab.
Kauj Ruam 10: Yuav Siv VU Meter li cas
VU Meter Qhia txog qib suab paj nruag.
Txuas 9V Roj Teeb rau Lub Roj Teeb clipper thiab Plug-in aux cable rau lub xov tooj/laptop/tab….. thiab ua nkauj.
Tam sim no Raws li cov nkauj yuav ua si zoo li LEDs yuav ci.
Hom no peb tuaj yeem ua Tsuas Yog Ib Tug Transistor rau VU Meter Circuit.
Ua tsaug
