2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:27

Xav hla cov khoom siv hluav taws xob thiab cov hniav nyiaj hniav kub - nws yog qhov qub heev. Yog li thaum peb nco txog nws, tshawb nrhiav tau muab ntau txoj haujlwm los hais txog qhov no. Txawm li cas los xij, feem ntau, cov khoom siv hluav taws xob txhais tau tias yog cov hniav nyiaj hniav kub los ntawm cov khoom siv hluav taws xob - cov khoom them nqi hnav hauv epoxide, cov ntsiab lus, pendants chips.

Peb xav ua cov hniav nyiaj hniav kub LED. Tsis yog xws li hauv Suav cov khoom ua si uas muag ntawm txhua qhov tig vim tias hauv lawv txhua yam yog qhov tsis nyiam - muaj ntau qhov haujlwm ntawm ntsais muag hloov los ntawm lub pob, thiab qee yam nyuaj dua thiab nthuav dua. Piv txwv li, cov hluav taws kub hnyiab ua rau lub teeb pom kev ib puag ncig kub hnyiab ntau dua hauv qhov tsaus ntuj thiab uas tab tom loj tuaj ntawm qhov pom kev. Los yog flickering hauv ib kauj ruam rau cov nkauj ib puag ncig. Los yog hloov xim nyob ntawm qhov kub nyob ib puag ncig. Los yog qhia qhov sov sov ntawm tus neeg nqa khoom. Hauv lwm lo lus, peb xav tau qee yam tshuaj tiv thaiv.

Kauj ruam 1: Npaj

Rau kev rov ua dua ntawm cov khoom siv hluav taws xob nws yuav xav tau rau koj:

• teeb rau cov laug (tus kav hlau, tus txhuam hniav, cov laug, cov pos hniav, chaw ua haujlwm, hluav taws xob);
• Attiny85 programmer (nws tuaj yeem sau tau ntau raws li kev qhia - lossis yuav kom tiav);
• Arduino IDE;
• cov ntaub ntawv pov thawj qhov project thiab qhov chaws - txhua yam tau pom tawm ntawm Github;
• teeb tsa ib feem, nws yog BoM (nws tuaj yeem rub tawm los ntawm no rau version 1, lwm qhov yuav txawv me ntsis) los ntawm tus naj npawb ntawm cov cuab yeej siv nrog nees nkaum feem pua saum toj no, cov ntsiab lus zoo muaj cov khoom yuav ploj thiab nws yog qhov tsim nyog yuav khoom;
• lub tsev lag luam hluav taws xob nyob ze lossis tom qab muaj nyob;
• tus kws tshaj lij hluav taws xob paub txog nyob ze uas tuaj yeem tshaj tawm cov lus qhia hauv qab no.

Ua tib zoo mloog! Kev teeb tsa cov khoom siv tshwm sim los ntawm kev siv cov hlau txuas, ua tib zoo saib xyuas uas tuaj yeem ua rau kub hnyiab thiab hluav taws kub. Thov, zam kev sim yog tias koj tsis muaj kev paub txaus hauv cheeb tsam no.

CEEB TOOM CEEB TOOM: koj tuaj yeem pom v1, v2 thiab v3 cov ntawv tais ceev tseg hauv qhov chaw cia khoom. Peb pom zoo kom siv qhov tseeb tshaj plaws ua rau nws tsis muaj kab laum.

Kauj Ruam 2: Ua Txoj Hauv Kev

Cov theem ua ntu zus kom tau txais cov cuab yeej ua haujlwm raws li hauv qab no:

1. Txhawm rau pib nws yog qhov yuav tsum tau xaj cov ntawv xov xwm hluav taws xob luam tawm:

   1. ua raws SeedStudio Fusion Gallery project nplooj ntawv - v1, v3
   2. nias lub pob xaj xaj - lub vaj huam sib luag uas nws yuav tsum tau xaiv ib qho nkaus xwb. Feem ntau nws yooj yim dua kom xaj 10 daim - yuav tsis ua tsawg dua.
   3. them thiab tos rau kev tsim khoom thiab xa khoom (feem ntau yog 3-4 lub lis piam);

2. Xaj cov khoom los ntawm BOM cov ntaub ntawv

   1. txiav txim rau lub tsev lag luam hluav taws xob nyob ze tshaj plaws. Kev saib xyuas tshwj xeeb yuav tsum tau them rau ntawm daim ntawv foos ntawm cov neeg tiv thaiv thiab cov condensers thiab tseem muaj ntau. Nws ua rau kev nkag siab los ua txhua txoj haujlwm nrog nees nkaum feem pua - kom tsis txhob poob thiab sib yuav;

   2. nws ua rau kev txiav txim siab xaj qee txoj haujlwm ntawm AliExpress lossis qee yam zoo li nws:

      1. SK2812 mini (ntawm lub vev xaib raug cim ua 3535)
      2. photoresistors;
      3. Cov neeg siv roj teeb CR2032.

3. npaj chaw ua haujlwm:

   1. nruab Arduino IDE;
   2. teeb tsa kev txhawb nqa ntawm Attiny microcontrollers hauv IDE - nws yog qhov zoo tshaj plaws los ua nws raws li cov lus qhia;
   3. rub tawm cov phiaj xwm phiaj xwm;
   4. qhib light_jewelry.ino (ore lwm.ino cov ntaub ntawv rau tam sim no) cov ntaub ntawv hauv Arduino IDE;
   5. xaiv hauv qhov ntsuas ntawm "Attiny85, 8 MHz", ua tus programmer - tswj tus programmer uas koj siv (raws li txoj cai - "Arduino as ISP");
   6. sim ua ke thiab xaws lub microcontroller uas tau yuav ntawm theem dhau los;
   7. yog tias txhua yam ua haujlwm tau zoo thiab IDE tsis muab tawm - nws muaj peev xwm txhawm rau lwm yam microcontrollers thiab dhau mus rau theem hauv qab no;

4. Thaum luam tawm cov phiaj xwm hluav taws xob tau los txog nws yog qhov tsim nyog los teeb tsa (soldering) ntawm cov khoom, suav nrog cov hauv qab no:

   1. tus yuam sij ntawm OLED ntawm lub rooj tsavxwm yeej yog nyob rau hauv ib qho rov qab ntawm ib lub xwmfab (tsim kev ua yuam kev hauv version 1, tsau hauv version 3), piv txwv li nws yog qhov tsim nyog yuav tsum tau tig nrog tig 180 degrees;
   2. nws yog qhov zoo dua los tawm ntawm ob txhais ceg ntawm lub microcontroller ua ntej kev teeb tsa ntawm qhov nqaim tshaj, yog li cov nti yuav nyob ntawm qhov tsawg kawg nkaus;
   3. nws yog qhov zoo dua los teeb lub photoresistor ntawm ob txhais ceg ntev uas tom qab ntawd nws tuaj yeem khoov nws kom tsis txhob tso tus kheej tawm;
   4. nws yog qhov zoo dua los tawm ntawm ob txhais ceg ntawm qhov hloov pauv uas tsis koom nrog hauv txoj haujlwm;
   5. lub roj teeb tuav ua ntej soldering nws yog qhov tsim nyog kom du tawm kom raug hauv thaj chaw ntawm kev sib cuag, nws txhim kho cov laug;
   6. nyob rau hauv rho tawm kev sib cuag ntawm lub roj teeb, nws yog qhov zoo dua los thov me ntsis solder ntawm lub platform - cov hlau uas twb muaj lawm tsis muab kev sib cuag zoo;
   7. tsis txhob hnov qab ntxuav tom qab teeb tsa cov pos hniav thiab, tej zaum, txhawm rau npog lub vaj huam sib luag pem hauv ntej nrog cov xim pleev xim tiv thaiv;
5. Yog tias tag nrho cov ntsiab lus dhau los ua tiav, tom qab teeb tsa lub roj teeb hauv lub cuab yeej thiab suav nrog LEDs ntawm lub vaj huam sib luag yuav ua kom pom kev liab, ntsuab thiab xiav - qhov taw qhia tias lub microcontroller tau pib ua tiav. Txwv tsis pub, theem zoo siab ntawm kev debugging yog qhov tsim nyog rau koj, ua ntej tshaj plaws, nws yog qhov tsim nyog los tshuaj xyuas qhov kev sib txuas ntawm cov khaubncaws sab nraud povtseg ntawm lub nkoj (peb raws li koj nco qab, muaj kev tsim khoom tsis raug).

Kauj Ruam 3: Ntxiv Kho Kom Zoo Nkauj

Feem ntau, cov cuab yeej npaj tau tuaj yeem pab tau tom qab sib dhos. Tab sis nws yuav tsis zoo nkauj li yog muab nws ib yam ntawm cov khoom tiav, tau siv txoj hauv kev ib txwm tsim los ntawm cov hlaws dai hniav nyiaj hniav kub.
