Kauj Ruam 2: Daim duab Circuit Court

Thawj kauj ruam koj yuav tsum tau ua nws yog saib ntawm daim duab qhia chaw, qhov no yog txoj hauv kev koj yuav txuas koj cov khoom siv kom ua haujlwm tau zoo. Yog tias koj tsuas yog siv tus protoboard nrog qee cov xov hlau tsuas yog tev qee cov hlua thiab txuas. Tab sis yog tias koj siv PCB Pawg Thawj Coj mus rau kauj ruam tom ntej. Kuv muab qee cov ntaub ntawv teev tseg los ntawm cov khoom tsis sib xws los ua kom yooj yim rau koj.

Kauj Ruam 3: PCB Board

Yog tias koj tau txiav txim siab los ua PCB Pawg Thawj Coj ua raws cov kauj ruam no, kom ua tiav qhov no, peb yuav tsum ua 5 yam:

1. Thawj qhov yog luam tawm lub Circuit Court, tsis txhob txhawj xeeb kuv txuas daim ntawv PDF nrog nws, koj yuav tsum luam tawm hauv daim ntawv Couche.
2. Qhov thib ob yog hlau txuas rau hauv PCB Pawg Thawj Coj, tsuas yog muab daim Couche ntawv tso rau sab tooj liab ntawm PCB Pawg Thawj Coj thiab kho kom haum kom haum, thaum koj pom tias cov kab hluav taws xob cov kab txuas mus rau PCB Pawg Thawj Coj kom raug tsuas yog tso tseg nws thiab tso PCB Board hauv qee qhov dej los ntxuav PCB Board.
3. Tom qab ntxuav lub Rooj Tswjhwm Saib PCB, muab qee cov Ferric Chloride Acid tso rau hauv cov yas tau txais qee cov dej, thiab tso rau hauv PCB pawg thawj coj, Ferric Chloride Acid yuav tsum npog tag nrho saum npoo ntawm lub rooj tsavxwm.
4. Thaum koj tsuas pom cov kab hluav taws xob khiav ntawm PCB Pawg Thawj Coj tshem tawm nws los ntawm Ferric Chloride Acid, ntxuav lub rooj tsavxwm nrog qee cov dej thiab xuab zeb nws nrog cov hlau tsis txhuam.
5. Thaum kawg, koj tsuas yog yuav tsum tau laum cov khoom tiv thaiv qhov.

Kauj Ruam 4: Kev Ua Haujlwm thiab Logic

Muaj nuj nqi:

Peb lub Hnub Ci Teeb pom kev zoo yuav ua haujlwm raws li cov xwm txheej hauv qab no:

HNUB:

Yog tias peb tus tswj xyuas pom lub hnub ci nws yuav txheeb xyuas tus nqi ntawm lub roj teeb, yog tias lub roj teeb nws ua tiav nws zoo, tab sis yog tias lub roj teeb nyob qis lossis nruab nrab them tus tswj yuav pib them lub roj teeb kom txog thaum nws pom tias nws ua tiav.

Hmo ntuj:

Yog tias peb tus tswj hwm tsis pom lub hnub ci nws yuav tig lub teeb ci LED, tab sis tsuas yog tias lub roj teeb nws nyob nruab nrab lossis ua kom tiav, tus tswj xyuas qhov tseeb ntawm tus nqi thaum hmo ntuj los ua qhov no. Yog tias lub roj teeb tau them qis, tus maub los tua lub teeb LED kom txuag lub zog thiab them lub roj teeb rau hnub tom ntej.

Logic:

Txhawm rau ua peb lub hnub ci teeb pom kev zoo peb yuav siv PIC12F675 microcontroller thiab nws zoo ib yam rau cov hloov pauv tus lej, peb yuav siv lawv txhawm rau txheeb xyuas tus nqi ntawm lub roj teeb thiab lub xeev ntawm hnub (Hnub lossis Hmo ntuj), ntxiv rau kev txheeb xyuas qhov ntsuas hluav taws xob tus nqi rau stablishing qib roj teeb (Ua kom tiav, Nruab Nrab, thiab Roj Teeb Tsawg), txhua qhov nyeem yuav siv qhov kev faib hluav taws xob nrog cov neeg tawm tsam lossis siv lub zog ntsuas (50k). Ntxiv rau qhov ntawd peb yuav siv 2 tus pin tawm rau qhib lub teeb thiab pib them lub roj teeb.

Kauj Ruam 5: Cov laug cam PCB

Thaum kawg koj tsuas yog yuav tsum tau muab cov khoom sib dhos tso rau ntawm PCB Pawg Thawj Coj thiab nws tau ua tiav!
