Nyob zoo cov neeg! Kuv rov qab nrog Lwm Cov Lus Qhia.

Thaum tsim cov phiaj xwm hluav taws xob, lub zog siv hluav taws xob yog ib qho tseem ceeb tshaj plaws ntawm tag nrho txoj haujlwm thiab ib txwm xav tau ntau lub zog hluav taws xob tso tawm. Qhov no vim tias cov ntsuas sib txawv xav tau qhov sib txawv ntawm qhov hluav taws xob thiab tam sim no kom ua haujlwm tau zoo. Yog li niaj hnub no peb yuav tsim qauv Lub Hwj Huam Muaj Ntau Lub Hwj Chim. Lub Hwj Huam Fais Fab yuav yog Arduino UNO Cov Khoom Siv Hluav Taws Xob uas yuav tso tawm ntau qhov hluav taws xob xws li 3.3V, 5V, thiab 12V. Cov ntaub thaiv npog yuav yog Arduino UNO cov ntaub thaiv npog nrog txhua tus pin ntawm Arduino UNO tuaj yeem siv nrog tus pin ntxiv rau 3.3V, 5V, 12V thiab GND.

Kauj Ruam 1: Yuav Tsum Kho Vajtse

Cov hauv qab no tau siv:

1. LM317 - 1 Chav Nyob

2. LM7805 - 1 Chav Nyob

3. LED - 1 Chav

4. 12V DC Barrel Jack - Chav

5. 220Ω Resistor - 1 Chav

6. 560Ω Resistor - 2 Chav

7. 1uF Capacitor - 2 Chav

8. 0.1uF Capacitor - 1 Chav

9. Burg Pins (20 hli) - 52 Chav Nyob

Kauj Ruam 2: Circuit Schematic & Ua Haujlwm

Daim duab qhia chaw thiab cov phiaj xwm rau Arduino Lub Hwj Huam Fais Fab Shield yog qhov yooj yim zoo nkauj thiab tsis muaj ntau qhov kev tso ua ke. Peb yuav siv 12V DC Barrel Jack rau lub zog hluav taws xob nkag rau tag nrho Arduino UNO Shield. LM7805 yuav hloov 12V rau 5V tso tawm, zoo ib yam, LM317 yuav hloov 12V rau 3.3V tso tawm. LM317 yog qhov nrov Voltage regulator IC tuaj yeem siv los tsim qhov sib txawv ntawm qhov ntsuas qhov ntsuas hluav taws xob.

Txhawm rau hloov 12V rau 3.3V peb tab tom siv 330Ω thiab 560Ω ua qhov faib hluav taws xob faib hluav taws xob. Nws yog ib qho tseem ceeb los tso lub capacitor tso tawm ntawm LM7805 thiab hauv av. Zoo sib xws ntawm LM317 thiab Av. Nco ntsoov tias txhua thaj chaw yuav tsum yog ib qho thiab qhov xav tau dav yuav tsum tau xaiv nyob ntawm qhov tam sim no ntws los ntawm Circuit Court.

Kauj Ruam 3: PCB Tsim

Tom qab ua qhov Circuit Court npaj txhij, nws yog lub sijhawm los mus tom ntej nrog tsim peb PCB siv PCB tsim software. Raws li tau hais ua ntej kuv tab tom siv Eagle PCB Designer, yog li peb tsuas yog xav hloov cov txheej txheem rau PCB Board. Thaum koj hloov cov phiaj xwm rau hauv pawg thawj coj, koj kuj yuav tsum tau muab cov khoom sib dhos tso rau hauv qhov chaw raws li qhov tsim. Tom qab hloov cov txheej txheem rau pawg thawj coj, kuv PCB zoo li cov duab tau hais los saum no.

Kauj Ruam 4: Kev Txiav Txim Siab rau PCB Tsim

1. Kab dav tuab yog yam tsawg 8 mil.

2. Qhov sib txawv ntawm lub dav hlau tooj liab thiab tooj liab yog qhov tsawg kawg yog 8 lab.

3. Qhov sib txawv nruab nrab ntawm kab mus rau kab yog yam tsawg kawg ntawm 8 mil.

4. Qhov me me qhov loj me yog 0.4 hli

5. Txhua txoj kab uas muaj txoj hauv kev tam sim no xav tau cov kab tuab

Kauj Ruam 5: Tshaj Tawm Gerber ntawm LionCircuits

Peb tuaj yeem kos PCB Schematic nrog ib qho software raws li koj qhov yooj yim. Nov kuv muaj kuv tus kheej tsim thiab cov ntaub ntawv Gerber.

Tom qab koj tsim cov ntaub ntawv Gerber koj tuaj yeem xa nws mus rau cov chaw tsim khoom. Raws li koj txhua tus paub, leej twg tau nyeem kuv Cov Lus Qhia yav dhau los, Kuv nyiam LIONCIRCUITS.

Lawv yog cov chaw tsim khoom PCB online. Lawv lub platform tau siv lub tshuab ua haujlwm tag nrho, koj yuav tsum tau xa cov ntaub ntawv Gerber thiab cov lus hais tuaj yeem pom tam sim. Lawv muaj cov kev pabcuam tsim tus nqi qis uas yog qhov muaj txiaj ntsig zoo rau cov haujlwm no. Sim lawv. Pom zoo heev.

Ntu-2 ntawm cov lus qhia no yuav tso tawm sai sai no. Txog thaum ntawd nyob twj ywm.
