Qhov WAS yuav yog kuv qhov nkag mus rau 'Tau Txais LED Tawm kev sib tw', tab sis kuv tau qeeb dhau. Kuv tau dhuav ib hnub. Kuv xav tsim ib yam txias. Ib me ntsis ntawm kev xav thiab tsis muaj dab tsi tuaj. Khawb los ntawm kuv cov thawv tsis zoo, Kuv pom cov khoom ntsuas qib qub. Kuv tau hla kuv tus phooj ywg qhov chaw tom qab hnub ntawd thiab peb tau muaj killfest hauv Halo 3. koj nyob ntawm yuav ua li cas koj tus kheej.

Rau Txoj Haujlwm no koj yuav xav tau: Ntoo ntoo LED cov ntsuas ntsuas qib (muaj nyob ntawm no) LED qhov koj xaiv.power supplyDiodes (yog siv cov khoom siv AC tso tawm) CablePotentiometer10 X BC558 lossis cov transistors zoo sib xws.

Cov khoom siv uas kuv siv Xav tau cov khoom siv nyob ib puag ncig 9 - 13 V DC, txog li 250 mA. Kuv muaj 12V AC 280mA Plugpack (tseem hu ua phab ntsa-warts) zaum ib puag ncig. Tab sis lub Circuit Court hu rau DC. Yuav ua li cas?

Kev daws teeb meem yog rau kuv los ua tus choj diode yooj yim (choj rectifier). Nws siv tsuas yog 4 lub zog me me diodes. Kuv tso lawv tawm, muab lawv tso ua ke, ntxiv cov khoom thiab viola! 15V tshem tawm. Zoo meej!

Kauj ruam 4: Transistors !

Tam sim no mus rau cov khoom siv. Nws xub muaj 3mm LED's tab sis cov no yuav tsum tau muab tshem tawm. Tom qab ntawd, kuv tshuaj xyuas qhov Circuit Court. LED thaum xub thawj tau siv qhov zoo ib txwm thiab lub nti hloov pauv qhov tso tawm kom pom lub teeb ci LED.

Qhov no txhais tau tias kuv xav tau PNP transistor. Nkag mus rau qhov yooj yim tab sis siv tau BC558. Qhov tseeb yuav ua dab tsi ntawm no. Txhua tus neeg yuav tsum muaj ntau ntawm cov no hauv lawv cov tub rau khoom. Yog tsis yog, zoo, koj yuav tsum tau mus qee yam. 10, qhov tseeb. Tom qab nrhiav tau lawv, koj yuav tsum txiav lawv cov coj mus rau hauv cov duab tshwj xeeb. Tsis yog 100% tsim nyog, tab sis ua rau lub neej yooj yim dua. Saib cov duab kom paub ntxiv. Khoov cov neeg sau khoom mus rau 90 ° ° tom qab lawv. Muab lawv tso rau hauv lawv cov qhov sib xws thiab muab lawv tso rau hauv.

Kuv siv ntoo li sawv ntsug rau cov zaub. Koj tuaj yeem siv lwm yam khoom, tab sis kuv muaj cov khoom seem uas nyob ib puag ncig. Koj siv koj li jigsaw, txiav lawv ua tej daim txog 5cm dav. Kuv qhov ntev txog 50 cm. Kos cov haujlwm ntawm qhov chaw koj xav tau koj li LED. Kuv tau splayed rau saum, deb ntawm TV. Drill lub qhov siv me ntsis zoo ib yam li koj li LED's. NCO TSEG: Kuv muaj 5 mm qhov muag teev, thiab kuv tau tswj kom pom me ntsis uas zoo li 4.9mm. LED haum zoo heev rau hauv lub qhov, yog li tsis muaj cov kua nplaum yuav tsum tau. Ntxuav lub qhov, thiab tom qab ntawd yog tias koj xav tau, muab rau pem hauv ntej lub tsho loj ntawm cov tshuaj tsuag xim dub matte. Le tawm cov phiaj ib sab kom qhuav.

Tom qab koj cov ntoo tau qhuav, nws yog lub sijhawm los ntxig thiab xaim cov LED. Thawb lub qhov muag mus rau tom qab ntawm lub plank. Yog tias lawv xoob me ntsis, tso ib qho kua nplaum PVA tso rau tom qab. Lawv tuav kom zoo.thov cov coj raws li qhia hauv daim duab. Tom qab ntawd ntxiv cov kab hauv av ib txwm. 5e Ethernet cable nyob ze, yog li kuv rub tawm qee qhov, tshem tawm cov rwb thaiv tsev thiab muab nws tso rau hauv cathode ntawm txhua qhov LED. Pom lub voj me me ntawm kab hauv av. Qhov no yog ua kom txuas tau yooj yim dua.
