Txiav ib daim iav
Txiav ib daim iav

Koj puas paub tias koj tuaj yeem siv tsuas yog lub microcontroller rau koj cov phiaj xwm Arduino? Koj tsis xav tau lub rooj sib tham xiav loj uas tuaj yeem nyuaj rau suav nrog! Thiab ntau tshaj qhov ntawd: nws yooj yim dua!

Kuv yuav qhia koj li cas los tsim PCB nyob ib puag ncig koj Arduino, tab sis ntawm iav!

Muaj ntau txoj hauv kev los ua iav PCB:

  • Koj tuaj yeem pleev xim tooj liab ntawm iav thiab tom qab ntawd siv cov PCB sib sau ua ke
  • Koj tuaj yeem txiav ib daim ntawv ntawm tooj liab nplaum nrog lub tshuab tshwj xeeb (lossis txawm tias yog lub tshuab luam ntawv 3D) thiab tom qab ntawd lo rau iav
  • Lossis… koj tuaj yeem ua nws ntawm tes thiab muab ib qho los ntawm ib qho txhua kab nrog kab xev tooj liab.

Cia peb pib!

Khoom siv

Rau qhov haujlwm no koj yuav xav tau:

  • ib daim iav (ua ntej txiav lossis tsis)
  • ntoo rau sawv ntsug
  • tooj liab daim kab xev
  • yooj yim SMD ib feem (LEDs, resistors, capacitors)
  • ib leeg zuj zus Arduino (µC + quartz) thiab tus programmer (FTDI)
  • ib opp
  • ib lub tshuab electret microphone

Thiab kuj qee yam cuab yeej los txiav iav (yog xav tau) thiab tsim cov ntoo sawv ntsug.

Kauj Ruam 1: Txiav Ib Daim iav

Txiav ib daim iav
Txiav ib daim iav

Rau qhov haujlwm tshwj xeeb no, koj yuav xav tau daim iav ntev ntev, tab sis koj tuaj yeem siv ib qho twg!

Siv cov cuab yeej tig thiab iav txiav daim disk, uas yooj yim zoo nkauj, tab sis koj yuav tsum maj mam maj mam.

Tom qab ntawd nrog cov ntawv xuab zeb, lossis cov cuab yeej siv txhuam, txhuam cov npoo ntawm daim iav.

Nws yuav siv qee qhov kev sim siab thiab ua yuam kev kom tau txais txiaj ntsig zoo (lossis txawm tias muaj txiaj ntsig txhua), yog li siv koj lub sijhawm thiab xyuas kom tseeb tias koj muaj iav txaus! Tus kheej, Kuv scavenge lub iav pane ntawm cov qub scanners, nws yog tuab thiab pheej yig.

Kauj Ruam 2: Laum Lub Qhov

Qhov qhov drilling yog qhov nyuaj tshaj plaws ntawm txoj haujlwm no!

Kuv kawm tau dab tsi:

  • Siv qhov tsom iav kom zoo
  • Pib nrog daim ntawv ntoo, txoj kev no, koj yuav tsis plam
  • Siv dej ntau thaum drilling
  • Laum maj mam
  • Thaum ib nrab mus, tig ib ncig ntawm daim iav thiab laum los ntawm no, txoj hauv kev no, koj yuav muaj lub qhov zoo

Thaum koj ua tiav nrog iav, koj tuaj yeem pib txheej txheem ntawm cov khoom.

Tso tsuas yog qhov loj, kom muaj lub tswv yim ntxhib ntawm qhov uas yuav tsum yog.

Tsis tas li, txiav ib co kab tooj liab me me (kwv yees li 1 txog 2 hli dav).

Kauj Ruam 5: Tiv thaiv/ua kom zoo nkauj iav Sawb

Ib kauj ruam ntxiv ua ntej pib tiag tiag!

Yog tias ib qho ntawm koj cov npoo tsis ncaj ncaj, koj tuaj yeem ntxiv tooj liab los nkaum nws.

Kauj Ruam 6: Thawj Cheeb Tsam

Thawj Cheeb Tsam!
Thawj Cheeb Tsam!

Nws yog lub sijhawm rau kev lag luam loj! Peb yuav muab tso ua ke thawj feem.

Pib los ntawm kev tso cov khoom tseem ceeb (zoo li lub microcontroller), thiab kos kab nrog tus cwj mem tsis ruaj khov uas koj yuav tsum muab tooj liab.

Tom qab ntawd, txiav me me ntawm koj daim ntawv tooj liab, thiab tso nws, tab sis nco ntsoov lwv koj kab ua ntej! Vim tias nws tuaj yeem pom tom qab.

Tam sim no koj tuaj yeem tso koj cov khoom sib xyaw thiab muab tshuaj txhuam rau nws, tsis txhob siv cov hlau kub dhau, thiab qeeb, lossis iav tuaj yeem tawg.

Nco ntsoov sim koj lub Circuit ntau zaus!

Kauj ruam 7: Auj! Tawg

Ouch! Tawg!
Ouch! Tawg!

Yog tias koj muab cov lus qhia kub dhau los nrawm rau ntawm iav, qhov kub ntawm qhov kub yuav siab dhau thiab iav muaj qhov muaj zog yuav tawg. Thiab nws tseem phem dua yog tias koj nyob ze thaj chaw uas tsis muaj zog lawm (zoo li ntug uas koj tau txiav, lub qhov, lossis lwm qhov tawg).

Txhawm rau zam qhov tawg zoo tshaj plaws, sim ua kom sov lub khob kom sib npaug thiab maj mam, los ntawm qhov ntxeev ntawm koj cov hlau rau nws.

Kauj Ruam 8: Tsoo Ib puag ncig iav

Warp ncig iav

Yog tias ib txheej tsis txaus, koj tuaj yeem mus tom qab lub iav, los ntawm kev ua rog nyob ib puag ncig.

Kauj Ruam 9: Kaum

Kaum
Kaum

Yog tias koj xav ntxiv lub kaum sab xis rau koj kab zauv (thiab tej zaum koj yuav xav tau nws), koj tuaj yeem ua tau

  • Khaws ib txoj kab rau saum lwm tus, thiab muab nws tso rau: yooj yim, tab sis tsis zoo tiag tiag IMO
  • Khoov kab, nws ntxiv ntim, thiab kuv pom nws zoo nkauj dua, tab sis nws nyuaj rau ua li ntawd, thiab nws tuaj yeem muaj zog dua
  • Siv ib feem los koom nrog ob txoj hauv kev

Kauj ruam 10: Lub sijhawm rau Arduino

Ok, tam sim no, peb yuav xav tau qee yam los tuav lub iav.

Nrhiav ib daim ntoo me me loj dua iav, thiab tseem ntev txaus kom haum rau 9V roj teeb.

Nrog lub laum xovxwm thiab lub kaum ntse ntse, ua qee qhov kom pib lub qhov uas iav yuav haum.

Tom qab ntawd, siv lub cuab yeej tig los hloov lub qhov, thiab xyuas kom lub iav tuaj yeem haum, tab sis tsis xoob dhau.

Nws yog lub sijhawm los ua hmoov av! Koj yuav tsum tau kos lub qhov rau lub roj teeb 9V thiab tus tswj hwm 5V.

Pib los ntawm kos cov duab plaub uas koj yuav kos, xyuas kom tseeb tias lub roj teeb yuav haum, thiab ntxiv qee cov npoo.

Tom qab ntawd, nrog lub router, kos tus duab ntawm lub duab plaub, thiab pib kos duab!

Nco ntsoov teeb tsa qhov kawg-nres kom raug, vim koj tsis xav hla mus rau lwm sab!

Kauj Ruam 18: Ntxiv Hloov
