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

Kuv tau sau ntau lub tshuab luam ntawv, vim li cas… vim tias nws pheej yig dua los yuav cov tshiab tsis tu ncua dua li yuav tus lej rau tus qub. Txawm li cas los xij, Kuv tau nkees nkees ntawm kev teeb lawv ntawm kaum ces txiav txim siab rub lawv sib nrug. Lawv yog cov khoom muaj nqis ntawm cov khoom, suav nrog cov raj zoo LED. Tom qab kev tshawb fawb ze dua, Kuv pom qhov tshwm sim yog 3528 RGB LEDs ntawm ib kawg ntawm lub raj. Thaum pib, Kuv muaj qee qhov SN74HC595N tso ncig thiab tau siv cov no ua ke nrog cov LEDs. Kuv kuj tau tshwm sim kom muaj qee qhov SK6812 RGBNW LEDs ntawm tes ib yam nkaus. Kuv tau ua kom haum nrog SK6812 LEDs thiab lawv tau ua kom haum yog li kuv txiav txim siab siv cov no tsis yog txhua qhov cuam tshuam nrog SN74HC595N hloov npe.

Kuv xav txog kev ua lub taub hau teeb ntau lub taub hau tab sis tom qab kuaj lub raj nrog lub ci ci tag nrho thiab muab piv rau cov teeb kuv twb muaj lawm kuv xav tias nws yuav ua lub rooj zoo dua.

Kauj Ruam 1: XEEM & TOOLS

Qhov:

- SK6812 RGB-NW LED lossis WS2811/WS2812b

- LED raj los ntawm lub tshuab luam ntawv nrog lub tshuab luam ntawv

- Digispark (ATtiny85) lossis Arduino lwm txoj hauv kev

- 22 ~ 24 AWG xaim

- USB txiv neej lub mloog pob ntseg lossis USB cable uas muaj txiv neej lub taub hau twb txuas lawm.

- Cov tshuaj tsuag xim dub

- Cov neeg pleev xim kab xev

Yeem:

- 750 Paracord (550 yog tias koj siv lub ntsuas cua me dua 24 ~ 26 AWG)

- 4 Zip-Ties

- Heatshrink tubing

Cov Cuab Yeej:

- 3D Tshuab Luam Ntawv

- Soldering hlau

- Qhov Nruab Nrab/Qhov D D me lossis Cov Lus C Me

- Tub Rog

- Cov kab hluav taws xob ua kua (xaiv tau, tab sis pom zoo)

- Cov kab hluav taws xob

- Multimeter los txheeb xyuas qhov ntsuas hluav taws xob thiab txheeb xyuas kom tsis muaj ib qho txuas nrog uas yuav tsum tsis yog!

- Kub kua nplaum phom

Kauj ruam 2: Npaj lub Tube

Xim:

Kuv tsis yog tus kiv cua ntawm kev zoo nkauj ntawm lub raj hauv nws lub xeev ntuj vim nws muaj qee yam seem ntawm cov kua nplaum uas lawv siv los tuav nws hauv lub tshuab luam ntawv. Kuv txiav txim siab pleev xim nws dub nrog qee qhov xim dub matte Kuv tau tshuav los ntawm qee qhov haujlwm. Kuv xav hais kom pleev xim nws ua ntej koj lo rau ntawm tus coj. Kuv tau tshwm sim los ua nws txoj hauv kev nyuaj thiab lo cov LED ntawm ua ntej pleev xim yog li kuv tau muaj qee qhov kev npaj ua xim ntxiv. Nco ntsoov tias koj tsis pleev xim sab tsis raug ntawm lub raj, uas yuav twv yuav raug hu ua lub damper ntawm txoj haujlwm.

LED:

Kuv txuas SK6812 LED nrog qee qhov superglue, koj tsis tas yuav siv superglue, tab sis nws tau ua kom yooj yim rau txuas; kua nplaum kub tseem yuav ua haujlwm. Cia nws tawv ua ntej messing nrog nws. Nco ntsoov tsis txhob muab kua nplaum rau ntawm lub ntsej muag LED lossis lub ntsej muag ntawm lub raj.

Kauj Ruam 3: Ua Lub Thawv

Kuv txuas cov STL cov ntaub ntawv kuv tsim. Lub thawv qhov ntev yog kwv yees li 35mm x 35mm x 35mm LxWxH, tsis txhob hais kuv. Kuv muaj lub khw nrog Stratasys Mojo luam tawm qhov no rau kuv yog li kuv tsis tuaj yeem hais tau zoo npaum li cas qhov no yuav luam tawm rau lwm tus. Thaum lub thawv ua tiav kub kua nplaum lub raj LED los ntawm sab saum toj. Lub qhov yuav tsum tsuas yog tuaj yeem haum lub raj ib ntawm ob txoj hauv kev, tab sis qhov tsis muaj teeb meem ua rau koj tuaj yeem tig lub hau yog tias koj lo nws tig mus rau lwm txoj kev. Cia cov kua nplaum kub zaum thiab tawv ib pliag ua ntej koj pib tso siab rau nws. Thaum cov kua nplaum kub tau teeb tsa koj tuaj yeem txuas rau peb lub xov tooj xav tau los khiav LED, Kuv yuav hla qhov no hauv cov kauj ruam tom ntej.

Kauj ruam 4: Muab tag nrho ua ke

Thaiv:

Thaum xaim SK6812 LED mus rau Digispark nco ntsoov ua kom cov xov hlau luv vim lawv txhua tus yuav tsum haum hauv qhov chaw me me.

Digispark => SK6812

Pin 0 => Data Pin

Pin 2 => GND Pin

5V Pin => 5V Pin

Kuv ua tus Pin 2 tus GND tus pin yog li yog tias koj xav ua haujlwm rau yav tom ntej kom tua ntawm lub sijhawm koj tuaj yeem ua los ntawm teeb tsa nws siab. Kuv paub nws tsis yog txoj hauv kev zoo tshaj plaws hauv kev ua thiab hauv kev coj ua, Kuv yuav tsum tau muab 5V Pin ntawm SK6812 rau Pin 2 thiab teeb tsa nws siab, Kuv xav tias thaum xub thawj txuas qhov no Kuv txhawj xeeb txog rub ntau mA los ntawm kuv/ O tus pin ntawm ATtiny85. Kuv yuav mus tom ntej thiab ua qhov no yav tom ntej yog li txoj kab thaiv kab mob zoo tshaj yuav tsum yog …

Digispark => SK6812

Pin 0 => Data Pin

Pin 2 => 5V Pin "+"

GND => GND Pin "-"

** Hloov kho cov cai yuav tsim nyog los ua haujlwm tam sim no tias Pin 2 yuav HIGH thaum nyob ntawm qhov hloov LOW.

Sleeving:

Yog tias koj zoo li lub paracord saib qhov no yuav tsum tau ua ua ntej khiav thiab txuas txhua yam. Kuv qhov lus pom zoo nkaus xwb yog siv cov xaim hluav taws xob me me ua rau cov xaim loj xaim yog qhov mob rub los ntawm. Kuv sim gluing cov xaim ua ke rau hauv ib lub xaim txhawm rau ua kom yooj yim rub los ntawm qhov tsis yog ntiv tes-cuam tshuam txhua yam; thaum kawg cov hlau tawg 80% ntawm txoj kev ntawd. Luckily, Kuv tuaj yeem nti-worm seem ob peb ntiv tes kuv tau sab laug. Yog tias nws muaj ntau dua li qhov kuv yuav tau muab tshem tawm qhov kev tua thiab pom lub USB qub cable los siv dua. Tom qab rub cov xov hlau los ntawm kab lus, Kuv tau sau tseg lub siab tias kuv yuav mus nrog qhov kev xaiv siv lub USB pigtail ua ntej rau cov haujlwm yav tom ntej. Cov xov hluav taws xob USB yuav tsum tau khiav hla lub qhov nyob rau sab ntawm lub thawv ua ntej koj muab nws txuas rau lub digispark txwv tsis pub… koj yuav pom nws. Kuv siv tus zip-khi los tuav lub xov tooj hauv lub thawv.

Kauj ruam 5: Coding

Kuv tau txuas cov cai kuv siv, tab sis koj yuav xav tau qee yam kom nws ua haujlwm.

1. Rub tawm txhua yam khoom tsim nyog kom tau digispark ua haujlwm (google tshawb nrhiav qhov no)

2. Rub lub tsev qiv ntawv Adafruit neopixel

3. Rub lub tsev qiv ntawv txhais cov xim txuas nrog

Tam sim no txhua yam ua haujlwm txoj cai yuav tsum ua kom nkag siab.

Teeb meem:

Xyuas kom tseeb tias digispark tsis txuas rau kom txog thaum tom qab koj nias lub pob upload.

Nco ntsoov tias digispark ua haujlwm nrog qee qhov qauv piv txwv.

Xyuas kom tag nrho koj cov kev sib txuas tau ruaj khov thiab koj cov kev sib txuas USB tsis thim rov qab.
