2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:24

Siv cov txhab nyiaj fais fab pheej yig los txhawb koj lub Arduino cov hluav taws xob ua rau muaj kev ntxhov siab heev nrog lawv cov hluav taws xob qis, pib tawm hluav taws xob.

Yog tias lub txhab nyiaj tsis pom lub zog txaus txaus-lawv tsuas yog kaw tom qab 30-40 vib nas this. Cia peb hloov kho Tus Kws Kho Mob lub cuab yeej kom rov sau dua qhov tsis txaus ntseeg no txuag lub zog.

Kuv tsim cov kab hluav taws xob me me uas kos tsuas yog ob peb mA ntawm qhov tam sim no thiab xav kom muaj peev xwm ua kom lawv los ntawm cov txhab nyiaj hluav taws xob yooj yim uas peb txhua tus tau pw ib puag ncig. Hauv Kev Qhia Niaj Hnub no, peb yuav hloov kho Tus Kws Kho Mob kom nyob mus ib txhis.

Peb tab tom yuav ntxiv ob tus tiv thaiv hla lub zog thiab cov pins hauv av kom ua rau lub zog me me ntawm lub txhab nyiaj hluav taws xob uas yuav dag nws kom nyob twj ywm tsuav yog Tus Kws Kho Mob Tus Kheej no tau ntsaws.

Khoom siv

Cia peb sau cov khoom peb yuav xav tau:

• Power Bank (ib qho yuav ua - Kuv nyiam cov no ib yam lossis ua koj tus kheej)
• Tus Kws Kho Mob (tus qauv no ua haujlwm zoo tshaj, tab sis lwm tus yuav ua haujlwm ib yam)
• Ob 200 Ohm resistors (1/4 watt loj)
• Qhov Chaw Nres Tsheb
• Qee cov laug (qhov no yog cov khoom siv zoo zoo)
• Polyimide High-Temperature Xev (aka. Kapton Daim Kab Xev) (tuaj yeem siv daim kab xev hluav taws xob lossis kua nplaum kub ib yam)

Kauj Ruam 1: Qhib Peb Tus Kws Kho Mob

Tus Kws Kho Mob uas kuv tau muab txiav ua ke siv plaub qhov yeeb yaj kiab me, ua rau lawv yooj yim heev qhib thiab hloov kho.

Siv lub ntswj taub hau me me, ua tib zoo cais cov ntu yam tsis ua rau lawv tawg. Siv koj lub sijhawm; nws yuav los sib nrug.

Ib zaug sib nrug, koj yuav pom tias muaj ib qho ntawm cov yeeb yaj kiab tiv thaiv hla cov duab LED. Tam sim no yog lub sijhawm zoo los tshem nws thiab txhim kho qhov pom los ntawm cov yas yas npog.

Tsis tas li, nco ntsoov tias peb muaj ntau qhov chaw ntxiv nyob hauv qab ib nrab ntawm Tus Kws Kho Mob kom ntxiv cov tshuaj tiv thaiv.

Kauj Ruam 2: Ntsuas Qhov Ntsuas Qhov Ntsuas

Siv lub ntsuas ntsuas, txheeb xyuas tus pin twg yog 5V thiab GND ntawm koj lub USB ntsaws. Qhov no yuav zoo ib yam ntawm txhua lub USB ntsaws, tab sis yog tias koj tsis paub nrog tus pin teeb, nws yog lub tswv yim zoo los tshuaj xyuas.

Hauv kuv qhov kev sim, kuv pom tias peb xav ntxiv 100 Ohm tsis kam hla 5V thiab GND pins - peb yuav tham txog lub zog xa tawm hauv ib feeb.

Hauv theem no, koj tuaj yeem tsoo ntawm 100 Ohm resistor nyob rau hauv qhov chaw thiab sim nws nrog koj lub txhab nyiaj hluav taws xob. Koj tuaj yeem siv 100 Ohm resistor lossis ob 200 Ohm resistors nyob rau hauv ib txhij, raws li kuv tau ua ntawm no.

Tej zaum koj yuav muaj lub txhab nyiaj fais fab uas yuav xav tau tus nqi tiv thaiv sib txawv. Yog tias yog qhov xwm txheej, sim txo tus nqi tiv thaiv thiab tom qab ntawd txheeb xyuas lub zog tawm mus, raws li peb yuav ua hauv cov kauj ruam tom ntej.

Kauj Ruam 3: Ntsuas Lub Hwj Chim

Ua ntej peb cog lus rau peb qhov kev tiv thaiv zaum kawg qhov tseem ceeb, cia peb ua lej rau ntawm peb lub zog tawm mus thiab xyuas kom peb nyob hauv qhov tshwj xeeb ntawm peb li 1/4 watt resistors.

Siv Ohm's Law, cia peb xam qhov tam sim no:

Kuv = V/R (Ohm txoj cai)

V = 5V R = 100Ohm I = 5/100 = 50mA

50mA yog tam sim no hla peb cov khoom, tam sim no cia peb suav lub zog:

P = 5V * 50mA = 250mW lossis 1/4 Watt

Siv ib 100 Ohm resistor yuav dissipate 1/4 watt uas yog nyob hauv thaj tsam ntawm peb cov lus qhia tshwj xeeb.

Txawm li cas los xij, kom muaj kev nyab xeeb txij li nws tau muab ntim rau hauv cov ntaub ntawv yas, cia siv ob lub 200 Ohm resistors ua ke. Qhov teeb tsa no yuav muab rau peb 100 Ohm tab sis nrog 1/2 watt dissipation.

Kauj Ruam 4: Kev Tso Tawm Kawg Kawg

Tam sim no peb paub peb tus nqi tiv thaiv kawg yuav tsum yog 100 Ohm, cia mus tom ntej thiab muab nws tso rau hauv qhov chaw.

Txij li thaum cov laug ntawm cov pob qij txha qub yog tej zaum tsis muaj cov laug, ua kom sov cov pob qij txha txuas tam sim no thiab ntws hauv qee qhov tshiab cov laug, qhov no yuav ua rau nws yooj yim dua los ua haujlwm nrog. Yog tias koj xav tau, koj tuaj yeem tshem tawm qhov qub qub thiab pib tshiab, tab sis nws tsis tsim nyog.

Kuv muab ob lub 200 Ohm resistors ua ke thiab muab lawv tso rau hauv qhov chaw.

Ceev faj tsis txhob ua tus choj txuas ntawm lwm tus pin, uas nyob ze heev. Tsis tas li, khaws tus tiv thaiv tus coj los ntawm kev kov qhov seem ntawm lub Circuit Court raws li nws yuav luv tawm tag nrho pawg thawj coj saib.

Hauv theem kawg, peb yuav ntxiv qee daim kab xev Kapton los tiv thaiv cov neeg tawm tsam.

Kauj Ruam 5: Ntxiv Qee Daim Kab Xev

Ntxiv ib daim me me ntawm polyimide high-temperature daim kab xev (Kapton daim kab xev) nyob ib puag ncig thiab nruab nrab ntawm tus tiv thaiv kab mob coj los tiv thaiv lawv kom tsis txhob luv. Yog tias lawv ua luv luv, nws yuav ua rau muaj kev tiv thaiv luv-Circuit hauv lub txhab nyiaj, thiab lub Circuit Court yuav kaw tag nrho.

Yog tias koj tsis muaj daim kab xev polyimide, daim kab xev hluav taws xob dub yooj yim yuav ua haujlwm, lossis koj tuaj yeem siv cov kua nplaum kub los tuav cov hlau lead hauv qhov chaw thiab tiv thaiv lawv kom tsis txhob kov lub rooj tsavxwm.

Kuv kuj nyiam kos npe rau Kuv Tus Kws Kho Mob los qhia tias lawv tau hloov kho. Muab ib daim me me ntawm daim kab xev daj tso rau tom qab ntawm tus kws kho mob them nqi ua qhov taw qhia.

Kauj Ruam 6: Xeem & Ua tiav Hack

Ntsuam xyuas koj tus kws kho mob uas tau hloov kho tshiab nrog koj lub txhab nyiaj fais fab. Thiab tam sim no nws yuav tsis muaj hwj chim rau koj.

Kuv sim kuv tus kws kho mob them nqi kho mob hauv tsib lub txhab nyiaj sib txawv thiab nws ua haujlwm zoo rau txhua tus ntawm lawv.

Txaus siab rau hack thiab tshaj tawm cov duab ntawm koj cov ntawv hauv qab no.
