Ncua Circuit rau hmo teeb

Peb txhua tus muaj teeb hmo ntuj zoo dua li peb lub txaj. Yog tsis yog, peb yuav tsum taug kev hauv qhov tsaus ntuj mus rau lub txaj tom qab peb hloov lub teeb hauv chav txaj. Zoo, yog tias koj tsim lub voj voog no yuav tsis muaj teeb meem zoo li no. Qhov Circuit Court no ua dab tsi yog khaws lub sijhawm ncua ua ntej tua lub teeb. Peb yuav ua kom pom qhov no siv LED tab sis koj tuaj yeem hloov kho nws txhua qhov chaw koj xav tau. Lub hauv paus tseem ceeb ntawm txoj haujlwm no yog D882 transistor. Nov yog NPN transistor. Koj tuaj yeem pom tus pinout thiab lub cev zoo li D882 transistor hauv daim duab.

Khoom siv

Cov npe hauv qab no suav nrog txhua yam tseem ceeb uas peb yuav xav tau hauv txoj haujlwm no. Txhawm rau kom yooj yim rau koj txhua qhov khoom siv tau muab txuas nrog los ntawm UTSource Yog li, koj tuaj yeem yooj yim xaj cov khoom.

Nov yog daim duab qhia chaw ntawm lub teeb hmo tsaus ntuj. D882 yog tus tswj ntawm LED. Raws li koj tuaj yeem pom LED txuas nrog 3.7V tus pin zoo thiab 100Ω resistor. Qhov kev tiv thaiv no yog txwv qhov tam sim no dhau los ntawm LED. Tus pin ntxiv ntawm LED txuas nrog tus sau ntawm D882 transistor. Lub hauv paus tus pin txuas nrog 10kΩ resistor thiab tom qab ntawd nws txuas nrog lub laub hloov. Ib qho 1000µF capacitor tseem txuas nrog rau qhov no thiab hauv av. Emitter ntawm D882 transistor txuas nrog hauv av.

1. Txuas tus pin tsis zoo ntawm 1000µF 10V capacitor rau tus pin emitter ntawm D882 transistor.

2. Solder tus sau tus pin ntawm D882 transistor mus rau 100Ω resistor.

3. Siv lub hauv paus tus pin ntawm D882 transistor mus rau 10kΩ resistor.

4. Cuam tus pin zoo ntawm LED mus rau ib qho ntawm cov laub khawm pins.

5. Siv tus laug txuas ntxiv ntawm lub laub khawm thiab LED raws li qhia hauv daim duab qhia chaw.

6. Txuas lub roj teeb 3.7V rau hauv Circuit Court raws li qhia hauv daim duab kos.

Kauj Ruam 4: Nws Ua Haujlwm Li Cas:

Thaum lub pob nyem lub capacitor raug them thiab lub hauv paus ntawm D882 transistor kuj tseem ua rau. Raws li lub hauv paus tau ua rau LED yuav tig rau. Raws li lub tshuab hluav taws xob tau them nws yuav muab lub hauv paus tam sim no txawm tias thaum hloov pauv. Yog li, LED yuav nyob twj ywm kom txog thaum them nqi ntawm lub capacitor tseem tshuav. Koj tuaj yeem hloov lub sijhawm ncua los ntawm kev hloov tus nqi ntawm lub capacitor

Xaus: Koj tuaj yeem siv ua hmo ntuj yooj yim. Lossis koj tuaj yeem siv qhov hloov pauv hloov ntawm LED thiab tswj AC cov khoom siv siv lub voj voog no ib yam.
