Nyob zoo phooj ywg, Qee lub sij hawm peb tsis nyiam qhov ci ci ntawm LED sawb thiab ntawm qhov uas peb tua qhov hloov pauv. Yog li hnub no kuv yuav ua LED sawb lub teeb ci tswj lub voj voog. Lub voj voog no peb tuaj yeem yooj yim tswj qhov ci ntawm LED sawb. ua tau yooj yim thiab cov Circuit no siv cov khoom tsawg dua.

Cia peb pib,

Kauj Ruam 1: Siv Txhua Qhov Raws Li Qhia Hauv Qab -

Cov khoom siv xav tau -

(1.) Transistor - D882 (NPN) x1

(2.) Resistor - 100 ohm x1

(3.) Potentiometer (sib txawv resistor) - 10K ohm x1

(4.) LED Sawb x1

(5.) DC Fais fab mov - 12V

Kauj Ruam 2: Khaws Cov Khaub Ncaws Pin ntawm Transistor

Quav Collector Pin ntawm Transistor
Quav Collector Pin ntawm Transistor

Transistor D882 muaj 3 -Pins -

Pin-1-Emmiter, Pin-2-Collector thiab Pin-3 yog lub hauv paus ntawm transistor los ntawm sab xub ntiag.

Ua ntej peb yuav tsum khawm tus pin tus pin ntawm transistor zoo li koj tuaj yeem pom hauv daim duab.

Kauj Ruam 3: Solder Transistor rau Potentiometer

Solder Transistor rau Potentiometer
Solder Transistor rau Potentiometer

Tom ntej no peb yuav tsum tau siv lub hauv paus txuas tus pin ntawm transistor mus rau tus lej thib ob ntawm potentiometer thiab

Emmiter tus pin ntawm transistor rau tus pin thib 3 ntawm lub hwj chim raws li koj tuaj yeem pom hauv daim duab.

Kauj Ruam 4: Solder 100 Ohm Resistor

Solder 100 Ohm Resistor
Solder 100 Ohm Resistor

Tom ntej solder 100 ohm resistor rau 1st tus pin ntawm potentiometer li solder hauv daim duab.

Kauj Ruam 5: Txuas LED Sawb Hlau

Txuas LED Sawb Hlau
Txuas LED Sawb Hlau

Tom ntej no peb yuav tsum txuas LED kab hlau txuas rau hauv Circuit Court -

Solder +ve hlau ntawm LED sawb rau 100 ohm resistor thiab

-ve xaim mus rau tus pin tus pin ntawm transistor zoo li koj tuaj yeem pom hauv daim duab.

Kauj Ruam 6: Tam sim no Txuas Cov Khoom Siv Hluav Taws Xob

Tam sim no Txuas Cov Khoom Siv Hluav Taws Xob
Tam sim no Txuas Cov Khoom Siv Hluav Taws Xob

Tam sim no peb yuav tsum txuas qhov kev sib txuas zaum kawg uas yog lub zog siv hluav taws xob.

Peb yuav tsum muab 12V DC cov khoom siv hluav taws xob tso rau ntawm Circuit no.

Solder +ve hlau ntawm lub hwj chim muab rau +ve hlau ntawm LED sawb thiab

-v xaim hluav taws xob xa mus rau emmiter ntawm transistor raws li koj tuaj yeem pom hauv daim duab.

Kauj Ruam 7: Yuav Siv Nws Li Cas

Tam sim no LED sawb ci ci Circuit Court yog npaj txhij.

Muab lub hwj chim rau hauv Circuit Court thiab tig lub pob qhov rooj ntawm potentiometer.

Maj mam raws li peb yuav txo/nce kev sib hloov ntawm lub pob qhov rooj ntawm lub zog zoo li qhov ci ntawm LED sawb tuaj yeem tswj tau.

Kuv vam tias qhov haujlwm no yuav pab tau hom no peb tuaj yeem ua LED Sawb Brightness tswj Circuit Court.

Yog tias koj xav ua ntau txoj haujlwm hluav taws xob zoo li qhov no ces Tsis txhob hnov qab ua raws li utsource.
