Yog tias koj yog tus pib thiab xav tau PCB nrog cov qauv kev cai … lossis lwm yam… qhov kev qhia no yog rau koj!

Peb yuav siv ob lub software zoo heev:

1. Inkscape: yog tus pub dawb thiab qhib qhov vector duab editor. Peb yuav siv nws los ua PCB cov duab, uas yuav siv tom qab hauv Fritzing los tsim PCB.

2. Fritzing: kuj yog pub dawb thiab qhib-qhov, yog cov cuab yeej peb yuav siv los tsim cov PCB (npaj cov ntu, ua cov txheej txheem, xa cov ntaub ntawv los tsim PCB).

Ob peb cov ntawv ua ntej pib…

1. Rau qhov kev qhia no, Kuv tsim PCBrain, uas yog PCB zoo li lub hlwb, raws li kuv li YouTube channel logo.

2. Lub hom phiaj ntawm qhov kev qhia no yog qhia koj li cas kev cai tuaj yeem ua tau yooj yim … yog li, tsis nco qab qhov yooj yim ntawm PCB nws tus kheej … nws yog kev kos duab ntau dua thiab tsuas yog piv txwv ntawm cov duab.

3. Txawm hais tias yooj yim siv software, Fritzing tsis txwv rau kev tsim qauv yooj yim … koj kuj tuaj yeem tsim PCBs nyuaj dua.

Ntawm no peb mus!

Kauj Ruam 1: Tsim Tus Qauv Zoo Nrog Inkscape

Inkscape muaj ntau yam cuab yeej rau tsim cov duab, piv txwv li: ellipses, arcs, polygons, hnub qub, spirals, kab dawb.

Koj tseem tuaj yeem ntsaws cov duab thiab siv nws ua "hauv paus" rau koj daim duab (zoo li kuv tau ua hauv PCBrain).

Tom qab ua tiav daim duab, ua raws cov theem hauv qab no kom tau txais cov ntaub ntawv nrog cov yam ntxwv xav tau.

1.1. Kho kom raug> Nyiam> Tus Cwj Pwm> Qhov pib yooj yim> 0, 0001

1.2. Txoj Kev> Yooj Yim

(Nco ntsoov tias tsis muaj dab tsi hloov pauv hauv daim duab. Tab sis yog tias koj tsis ua, cov duab yuav hloov pauv thiab cov chaw tsim khoom yuav tsis tuaj yeem tsim cov PCB. Yog li ntawd, tsis txhob hla cov kauj ruam no.)

1.3. Ntxiv sublayer lub npe hu ua "board" nrog rau daim qauv ntawm daim duab/duab.

1.4. Ntxiv sublayer lub npe hu ua "silkscreen" nrog rau daim qauv ntawm daim duab/duab.

(Cov "silkscreen" sublayer yuav tsum nyob saum "board" sublayer. Rho tawm daim duab hauv "txheej" txheej - rau "txheej" txheej "Kuv txhais tau tias" Txheej 1 ", uas inkscape twb muaj nyob hauv daim ntawv tshiab lawm.)

1.5. Sau thiab Stroke rau "silkscreen": tsis muaj sau, mob stroke dawb, dav ntawm tus mob stroke 0, 008 nti.

1.6. Sau thiab Stroke rau "board": ntsuab sau, tsis muaj mob stroke.

1.7. Xaiv ob daim duab thiab mus rau "Kho thiab faib", thiab "Chaw ntawm txoj kab ntsug", tom qab ntawd "Chaw ntawm kab rov tav".

1.8. Cov Ntaub Ntawv> Cov Khoom Siv Khoom> Hloov nplooj ntawv rau cov ntsiab lus> Hloov nplooj ntawv rau kos duab lossis xaiv

1.9. Nrog XML Editor, hloov tus lej ID ntawm "pawg thawj coj saib" npe nws li "board".

1.10. Hloov tus ID ntawm "silkscreen" txheej npe nws li "silkscreen".

1.11. Hloov tus ID ntawm txoj hauv kev hauv "pawg thawj coj" txheej, npe nws li "boardoutline".

1.12. Txuag cov ntaub ntawv li Plain SVG (File> Save As…).

Kauj Ruam 2: Tsim PCB nrog Fritzing

Raws li kuv tau hais ua ntej, Fritzing yog qhov yooj yim heev rau siv txawm tias rau cov pib tshiab … tab sis tau kawg kev paub tsawg kawg ntawm cov khoom siv hluav taws xob xav tau.

Fritzing muaj ob peb ntu uas koj tuaj yeem rub thiab poob rau hauv PCB. Koj kuj tseem muaj kev nkag tau rau ntau yam Sparkfun cov khoom txheej txheem, Arduino cov laug cam thiab cov txheej txheem thaiv.

Tom qab koj txoj haujlwm Fritzing tiav, ua raws cov theem hauv qab no.

2.1. Txoj Kev> Tsim Txoj Cai Txheeb Xyuas (DRC)

2.2. Cov Ntaub Ntawv> Export> rau Ntau Lawm> Ntxiv Gerber (RS-274X)

Kauj Ruam 3: Hloov Txoj Haujlwm mus rau qhov tseeb PCB (Los Ua Ke thiab Ua Haujlwm)

Koj tuaj yeem khawb PCB koj tus kheej hauv tsev. Tab sis kuv xaj PCB nrog cov chaw tsim khoom lag luam (JLCPCB - https://jlcpcb.com), uas muab tus nqi pheej yig thiab tsim khoom zoo. Yog li ntawd, tsis muaj laj thawj ua li ntawd hauv tsev. Ntxiv rau koj yuav muaj kev tshaj lij saib PCB tsim los ntawm koj!

Tom qab tau txais cov phiaj hauv kuv lub rooj cob qhia, kuv tsuas xav tau qee cov ntaub ntawv thiab cov cuab yeej teev hauv qab no los sib sau ua ke.

Cov khoom siv hluav taws xob:

• 8x 3 hli LED;
• 8x 270 ohm 1/4W resistor;
• tus pin headers.

Cov ntaub ntawv:

• soldering hlau;
• soldering flux muab tshuaj txhuam;
• kab xev

Cov Cuab Yeej:

• soldering hlau;
• txiav pliers

Kev sib dhos thiab sib dhos ntawm txoj haujlwm no yog qhov yooj yim heev.

Pib los ntawm kev tso thiab siv cov LEDs, tom qab ntawd tus tiv thaiv thiab tus pin taub hau. Kuv siv me ntsis ntawm cov tshuaj txhuam cov tshuaj txhuam kom ua haujlwm yooj yim dua. Cov tshuaj txhuam ua kom PCB tsis huv. Txhawm rau ntxuav nws, Kuv siv lub paj rwb swab nrog acetone.

Kauj ruam 4: Arduino Code

PCBrain muaj tus pin teeb tsa los txuas rau Arduino UNO board.

Txhawm rau ua kom tiav txoj haujlwm no, Kuv tau tsim txoj cai yooj yim rau ntsais lub teeb LEDs, simulating lub hlwb sib txuas.

Cias txuas Arduino rau lub PC, qhib Arduino IDE nrog cov lej nkag, thiab xa mus rau lub rooj tsavxwm.

Vam tias qhov no tuaj yeem pab tau rau ib tus neeg.

Koj tuaj yeem siv txhua cov ntaub ntawv sib qhia ntawm no thiab muaj mus rau koj tus kheej.

Txawm hais tias tam sim no cov theem tau yooj yim, nws tau siv sijhawm me ntsis rau txhua yam los ua haujlwm … yog li kuv tau sim sau tag nrho cov lus qhia ntawm no kom nws yooj yim heev rau cov uas tab tom nrhiav txoj hauv kev yooj yim ntawm kev tsim cov qauv kev cai.

Thov kuj saib cov vis dis aus… nws yuav tsum qhia meej ntxiv cov kauj ruam. Thiab yog tias koj nyiam nws, txiav txim siab tso npe rau kuv tus YouTube channel: youtube.com/mechdickel

Ua tsaug!
