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

Kauj ruam 1: Koj Yuav Tsum Ua
Txhua ntu muaj nyob ntawm
Daim ntawv teev npe -
LED - 5 hli Yuav
IC - 555 Yuav
IC -7805 Yuav
IC - 74LS164 Yuav
IC - ic puag 8 tus pin Yuav
14 pin Muas
Diode - 1N4148 Yuav
Transistor bc547b
los yog 548b Yuav
Capacitor - 0.01 Yuav
10uf/50v Yuav
Potentiometer 100K Yuav
Resistor - 10K Yuav

& 12 volt adapter rau lub zog siv.
Kauj Ruam 2: Ua LED Board
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.
Kauj Ruam 3: Ua Tus Tswj Xyuas Pawg & Koom nrog LED Board
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.
