Nws yog qhov haujlwm hluav taws xob yam tsis muaj phiaj xwm lossis ib qho micro controller

koj tuaj yeem ua koj tus kheej cov lus tshwj xeeb cov lus coj coj los siv lub rooj sib tham no

hauv qhov haujlwm no kuv tau siv hloov pauv resistor IC 74ls164 thiab IC 555 rau kev ua yeeb yaj kiab. koj tuaj yeem ua pawg thawj coj nrog 8 tsab ntawv

Kuv ua hauv kuv txoj haujlwm "Zoo siab txais tos" lo lus nws yog 7 lo lus.

Txhua lub Cheebtsam ntawm txoj haujlwm no muaj nyob ntawm

Kuv ua hauv kuv txoj haujlwm "Zoo siab txais tos" lo lus nws yog 7 lo lus

koj tuaj yeem ua koj tus kheej cov lus tshwj xeeb coj coj pawg hu nkauj siv lub voj voog no txog 8 tsab ntawv

Txhua tus coj qhov zoo & tsis zoo pins tau txuas nrog etch lwm yam (ib tsab ntawv)

pins tsis zoo yog mus rau tus lej pin ntawm transistor Cov pins Zoo txuas nrog 680 ohm resistor & txhua tus tiv thaiv mus rau 12 volt zoo

yog tias koj lo lus loj & koj siv ntau lub LEDs hauv ib tsab ntawv ces siv tus tiv thaiv qis dua 680 ohm.

rau cov phiajcim loj dua koj tuaj yeem siv lub zog cais cais rau pawg thawj coj saib.

IC - 74LS164 & IC 555 khiav ntawm 5v volt yog li kuv siv ntawm no 5 qhov ntsuas hluav taws xob IC 7805

Potentiometer 100K txuas nrog tus pin 6 & 7 ntawm timer IC 555. koj tuaj yeem tswj cov duab nrawm siv qhov Potentiometer no

8 daim 547b transistor siv rau tsav lub leds & lwm qhov ib qho transistor 547b rau rov pib dua tus pin

tam sim no ua hluav taws xob siv daim duab hluav taws xob ntawm daim npav vero

tom qab ntawd koom nrog transistors tus lej pin rau coj pawg thawj coj tus lej tsis zoo ntawm txhua tsab ntawv

& koom nrog 12 volt zoo rau coj pawg thawj coj zoo qhov twg txhua 680 ohm resistors txuas nrog.

hwj chim nws nrog 12 volt 1 amp dc zog adapter.
