Lub tshuab ntsuas hluav taws xob hluav taws xob tuaj yeem siv los tshuaj xyuas yog tias ib yam khoom tsis zoo lossis raug them zoo. Peb tau ua raws cov theem hauv qab no hauv youtube video:

Cov ntaub ntawv:

FDS8958A nti- muaj N & P channel txhim kho hom zog lub zog ua haujlwm

Lub thawv yas

2 qhov loj me ntawm tubing

Roj teeb

Jumper xov hlau

2 LEDs

2 Hloov

Cov laug thiab hlau

Phom phom

1 K ohm resistors

Kauj Ruam 1: Npaj Lub Thawv

1. Laum ib lub qhov rau hauv lub qhov me me ntawm cov tubing.
2. Ntxig tubing me me hla lub qhov thiab kua nplaum rau lub hau. Xaub cov tubing loj dua nws thiab kua nplaum. Kaw qhov kawg ntawm tubing nrog kua nplaum.
3. Txiav 3 daim me me ntawm cov tubing me thiab 2 qhov ntev dua. Qhov no yuav yog tus ncej uas tuav txhua yam hauv qhov chaw. Kuaj lawv raws li pom saum toj no.
4. Muab ob txoj hlua tso rau ntawm tus ncej thiab hla sab hauv ob sab.

Kauj ruam 2: Schematic

Nov yog daim duab ntawm cov txheej txheem peb tau ua raws thiab tus qauv ntawm Circuit Court ntawm PVC board. Ntawm no peb tuaj yeem ua piv txwv zoo dua qhov kev sib txuas peb tau ua. Pins 1-0 ntawm lub nti txuas nrog cov hloov pauv. Cov hloov pauv tso cai rau tshem tawm cov nqi; rov pib dua qhov system. Pins 5-8 ntawm qhov hloov pauv tau txuas nrog 2 LEDs, uas txuas nrog rau 1 K ohm resistors. Cov resistors tau txuas nrog hauv av thiab lub zog thiab mus rau lwm sab ntawm cov hloov khoom siv.

Kauj ruam 3: Soldering

Siv cov txheej txheem los ntawm cov swb yav dhau los txhawm rau txuas cov nti rau cov hloov pauv nrog cov hlau txuas thiab cov laug. Yog tias koj muaj kev paub me me nws yuav yooj yim dua los siv IC adapter thiab/lossis PVC lub rooj tsav khoom kom yaj rau. Txwv tsis pub koj tuaj yeem ua txhua yam ncaj qha mus rau tus ncej tom qab cov txheej txheem zoo li peb tau ua.

Kauj ruam 4: Kawg

Nov yog qhov khoom kawg. Nrog 3 daim kab xev koj tuaj yeem sim tawm koj lub cuab yeej. Muab 3 daim kab xev sib dhos rau ntawm ib lub rooj thiab tab qhov kawg. Rub tawm thawj ob daim maj mam thiab tom qab ntawd muab lawv sib nrug nrog lub zog. Tam sim no ib daim yuav raug them zoo thiab lwm qhov tsis zoo. LED uas koj tau txuas nrog lub hwj chim (liab ib qho) yuav txheeb xyuas qhov tsis raug thiab lwm qhov nqi zoo (xiav ib qho). Yog tias kuaj pom thaj chaw zoo N-channel ua haujlwm vim tias P-channel yuav thawb tawm txhua qhov kev tsub nqi zoo thiab hloov pauv rau qhov tsis zoo. Ua tsaug rau kev nyeem peb cov lus qhia thiab ua hmoov zoo nrog koj txoj haujlwm!
