Qee lub sij hawm koj xav tau qee qhov ntsais ntsais LEDs, rau kev kho kom zoo nkauj chrismas, kos duab kos duab lossis tsuas yog kom muaj kev lom zem nrog ntsais ntsais ntsais ntsais. Kuv yuav qhia koj yuav ua li cas thiaj ua rau pheej yig thiab yooj yim Circuit Court nrog txog li 6 ntsais muag LEDs. Nco tseg: Nov yog kuv thawj qhov kev xav tsis tau thiab kuv tsis yog tus neeg hais lus Askiv ib txwm - yog li thov zam txim rau kuv qhov ua yuam kev.
Kauj Ruam 1: Qhov Koj Xav Tau
Yog li koj xav tau qee qhov khoom siv hluav taws xob pheej yig, ntawm no peb mus:- 1 CMOS 74C14- nws yog ib qho me me thiab pheej yig heev microchip, peb siv nws los tsim cov oscillators kom ua rau peb cov LED ntsais ntsais- qee lub xov hlau txuas- lub khob cij los lo cov khoom ntawm nws- lub 9V thaiv cov roj teeb nrog cov roj teeb rau kev sim ntxiv lub zog ntsuas ib puag ncig txog li 1 Mfor txhua LED-Circuit (koj tuaj yeem ntxiv txog 6 rau ib lub nti) peb xav tau- ib qho LED;-)- lub capacitor (ncig 4, 7 µF, koj yuav sib txawv tus nqi kom tau txais qhov sib txawv ntsais ntsiag to)- tus tiv thaiv 100k-200k- tus tiv thaiv kom txwv tus coj tam sim no, ib puag ncig 1-3k
Kauj Ruam 2: Okay Cia Ua Ke Ua Ke
cia peb mus rau peb thawj zaug blinky cirtcuit. Muab CMOS Chip tso rau hauv nruab nrab ntawm daim ntawv qhia zaub mov raws li qhia hauv daim duab Txuas tus pin 7 ntawm lub nti nrog hauv av (-) thiab tus pin 14 nrog VCC (+)-tsheb npav ntawm lub khob cij. Tam sim no txuas lub capacitor rau tus pin 1 thiab hauv av (xyuam xim rau cov lus qhia, muaj qhov rho tawm luam tawm ntawm Lub Cap - cov hlau lead mus rau hauv av). Tso 100k-200k resistor ntawm tus pin 1 thiab 2 ntawm tus nti. Tom qab ntawd koj yuav tsum tau ntxiv cov kab tawm tsam (1-3k) ntawm tus pin 2 thiab LED. Ua tib zoo qhia qhov raug ntawm LED. Cov ceg luv mus rau hauv av Kuv vam tias koj yuav pom nws ntawm daim duab Yog tias koj ua tiav, txuas tus batty mus rau ntxiv thiab rho tsheb npav ntawm lub khob cij thiab koj thawj LED yuav tsum pib ntsais muag.:-) Qhov ntawd lom zem! Cia peb mus tom ntej, ntxiv ntau LEDs …
Kauj Ruam 3: Ntxiv Ntau Teeb
Raws li koj tuaj yeem pom ntawm daim duab ntawm lub nti (cov kauj ruam kawg) muaj 6 inverter Circuit Court ntawm lub nti, yog li koj tau ua dab tsi nrog tus pin 1 thiab 2 - koj tuaj yeem ua nrog tus pin 3 thiab 4, 5 thiab 6, 8 thiab 9 thiab ntxiv rau … yog li cia ua kom vwm thiab ntxiv ntau lub voj voog LED … Koj tuaj yeem siv txhua qhov Circuit Court rau koj qhov muag ntsais muag, yog li koj yuav muaj txog 6 ntsais LEDs ntawm ib lub nti. Koom nrog cov lus qhia. Thawj qhov ua mus los ntawm tus pin 1 mus rau tus pin 2. Ntawm lwm sab ntawm lub nti qhov kev taw qhia yog tsom iav. Yog li nws mus piv txwv los ntawm tus lej 9 txog 8. Yog tias koj ua qhov no ntawm lub khob cij yuav tsum ceev faj kom tsis txhob luv ntawm ntu!
Kauj Ruam 4: Tau Txais Kev Tswj Ntau Yam
Peb lub voj voog ua haujlwm zoo ib yam li oscillator Circuit ntawm Lady Adas Drawdio ua haujlwm. Qhov no yog descibed nyob ntawd. Yog li nrog qhov loj resistor (100k-200k) koj tuaj yeem hloov qhov ntsais ntsais. Tso tus tiv thaiv me me nyob ntawd, koj yuav pom cov LED ntsais sai dua. Qhov me dua tus resistor, qhov ntau dua. Koj kuj tseem tuaj yeem hloov pauv ntau zaus los ntawm kev hloov lub tshuab hluav taws xob ib yam nkaus. Yog li yog tias koj xav kom muaj kev tswj hwm tag nrho, koj tuaj yeem ntxiv lub zog ntsuas hluav taws xob hloov chaw tiv thaiv. Yog li koj tuaj yeem hloov pauv zaus hauv lub sijhawm tiag tiag;-).
Kauj Ruam 5: Tau Tsim
Yog li qhov no yog lub voj voog yooj yim heev kom ua rau qee cov LEDs ntsais muag. Koj tuaj yeem siv nws rau koj kev kho kom zoo nkauj chrismas, lossis yooj yim kom muaj lub teeb pom kev me me hauv koj chav. Ua kom muaj tswv yim thiab ua koj cov khoom ntsais nrog nws. Yuav zoo saib qhov koj tau ua nrog nws.
Kuv tau ua qhov blinky geeky tabletop kho kom zoo nkauj raws lub Circuit: Ua tsaug rau kev nyeem. Muaj kev lom zem nrog lub tsev!
