Thawj qhov uas yuav tsum tau ua, thiab tam sim no kuv tau nkees tab sis tsim nyog, peb yuav tsum ntsuas LEDs. Txhawm rau ua qhov ntawd, peb yooj yim txuas cov khoom siv hluav taws xob piv txwv li 9V Roj teeb thaiv nrog clip rau lub nkoj loj. Raws li koj tuaj yeem pom hauv daim duab 3 tus Pin ntev tshaj plaws ntawm LEDs yog Anode (+) yog li koj txuas tus pin no rau +9V ntawm lub roj teeb. Tam sim no ua ntej txuas GND rau tus kheej xim Cathodes (Liab, Ntsuab, Xiav) ntxiv 220Ohm resistor rau txhua tus cathode kom txwv qhov tam sim no. Tam sim no muaj kev lom zem sim txhua xim ntawm txhua 216 LEDs.

Hauv cov kauj ruam tom ntej peb yuav npaj cov ntsuas LEDs kom peb tuaj yeem yooj yim sib sau ua ke hauv kab tom qab.

Kauj Ruam 3: LED Kab

Ua ntej peb tuaj yeem tso cov LEDs rau hauv lawv cov kab sib txawv peb yuav tsum khoov thiab txiav cov hlau lead.

Raws li koj tuaj yeem pom hauv thawj daim duab kuv tau yooj yim rub lub 8mm qhov (rau 8mm LEDs) rau hauv ib qho ntoo thiab drilled 3 qhov kev xyaum me me mus rau sab laug ntawm lub qhov LED thiab lwm mus rau sab xis ntawm lub qhov. Cov kev xyaum no yog cov cim rau khoov cov coj kom raug thiab yuav tsum muaj qhov deb li ntawm 1cm ntawm nruab nrab ntawm lub qhov rau LED.

Cov txheej txheem no tau tshoov siab los ntawm Steve Manley, koj tuaj yeem pom cov vis dis aus ntawm nws ua qhov no hauv kev hloov pauv me ntsis hauv YouTube.

Ua ntej koj txiav thiab khoov txoj hauv kev ib puag ncig kev xyaum raws li pom hauv daim duab 2 thiab 3, nco ntsoov tias kev taw qhia ntawm cov coj coj mus rau daim duab 1 (Xiav nyob rau sab saum toj mus rau sab laug, tom qab ntawd ntsuab, tom qab ntawd anode + mus rau sab xis, thiab liab sab laug dua). Lub voj voos uas koj khoov rau hauv txoj hauv kev yuav tsum muaj lub taub loj txaus kom haum rau cov xaim tooj liab xaim (0.8mm). Cov kauj ruam no ua rau nws zoo nkauj yooj yim dua los ua kom cov LEDs nyob hauv qhov chaw zoo.

Tam sim no tias txhua qhov LED tau npaj, peb xav sau lawv ua kab ntawm 6 qhov twg Anodes (+) txuas nrog:

1. Ua tus jig me me raws li pom hauv daim duab 6, laum 6 qhov (txoj kab uas hla 0.8mm) nrog qhov nrug ntawm 2.5cm mus rau lub qhov tom ntej. Qhov no tso cai rau peb haum 6 LEDs ib lub sijhawm rau hauv jig
2. Txhawm rau txuas cov anodes peb xav tau qhov ncaj tinned tooj liab xaim ntawm ~ 16cm ntev (nrog qee qhov npoo ntxiv). Txhawm rau kom tau cov xaim zoo thiab ncaj koj tuaj yeem txuas ib kawg ntawm cov xaim mus rau piv txwv li siv lub laum hluav taws xob, ruaj ntseg txog 2m ntawm cov xov hlau ib zaug ntawm lub rooj, tom qab ntawd tuav lub laum kom xaim tau nthuav dav thiab nruj thiab muaj zog ntawm qhov laum rau ob peb feeb nrog ncaj tawm cov xaim nrawm heev. Tom qab ntawd koj tuaj yeem txiav xaim txoj cai ntawm qhov chaw koj ruaj ntseg daim. Koj kuj tseem tuaj yeem siv ob rab riam thiab kaw qhov xaim me me ntawm ib lub sijhawm, tab sis qhov ntawd yog qhov ntau dua
3. Thaum koj muaj 16cm cov xov hlau ntev koj coj lawv hla Anode (+) qhov ntawm LEDs hauv lub jig thiab muab cov kab xaim Anode txuas rau xaim (Daim duab 7)

Rau tag nrho lub voos xwmfab peb yuav xav tau 6x6 = 36 ntawm cov kab LED no

Kauj Ruam 4: Txheej Los Ua Ke

Raws li kuv tau hais ua ntej, peb yuav ua ntau txheej txheej ntawm lub voos xwmfab, tab sis rau kev sib dhos nws yooj yim dua los tsim 6 Phab Ntsa ntawm 6x6 LEDs thiab tom qab ntawd sib sau ua ke lawv ib sab thiab yooj yim khiav ib lub xaim tooj liab xaim txuas nrog anodes ntawm kab hauv ib txheej ua ke.

Ceev faj tias cov kauj ruam no siv sijhawm ntau thiab ua siab ntev txhawm rau ua kom raug, nyob rau hauv tag nrho koj yuav tsum tau sib dhos ib puag ncig 1000 cov laug txuas rau kev tsim yog li siv koj lub sijhawm!

Txhawm rau tsim LED Phab Ntsa:

1. Rau jig: Peb xav tau ib daim ntoo nrog 6 kab txua ntoo kom haum 6 kab ib kab saum toj ib sab los tsim phab ntsa. Koj tuaj yeem pom jig nws tus kheej hauv daim duab 2 (nrug ntawm kab: 2.5cm)
2. Koj haum rau 6 kab ntawm LEDs rau hauv daim duab, nrog Anode xaim lub ntsej muag nqes mus rau hauv kab txua ntoo, kom 3 Cathodes (R, G, B) ntsej muag
3. Txhawm rau txuas Cathodes uas nyob saum ib leeg ib leeg (saib daim duab 2) peb xav tau qee cov xov hlau ntxiv (yog li peb ntxiv 6 Kab x 3 Cathodes x 6 Phab Ntsa = 108 tinned xaim xaim raws li tau piav qhia hauv kauj ruam kawg))
4. Xaub cov xov hlau los ntawm hauv qab ntawm kab ntawv los ntawm lub qhov ntawm Cathodes mus rau kab saum toj kawg nkaus thiab muab cov xaim txuas tso rau ntawm txhua qhov LED

Koj ua qhov no 6 zaug kom tau 6 phab ntsa ntawm LEDs.

Tam sim no peb tuaj yeem sib dhos Cov Phab Ntsa mus rau hauv lub voos xwmfab nws tus kheej. Tab sis kom tuav lub voos xwmfab, peb yuav tsum tsim qee yam ntawm lub dav hlau hauv av. Txog qhov no kuv tsuas siv qee cov plywood nyias thiab drilled me 0.8mm qhov rau hauv nws, kom haum cov xov hlau dai los ntawm qis LED Kab (rau txhua 6 LED Phab Ntsa). Kev ntsuas ntsuas rau lub qhov ntawm ib qho LED tau sau tseg hauv Kauj Ruam 3 thiab qhov kev ncua deb ntawm txhua LED yog 2.5cm.

Nrog lub qhov nyob hauv qhov chaw tam sim no peb coj thawj phab ntsa thiab txav nws mus rau hauv lub qhov ntawm sab laug ntawm lub plywood. Cov kab LED nyob hauv qab yuav tsum zaum sab xis ntawm cov ntoo, yog li thaum kawg txhua phab ntsa tau sib dhos zoo ib yam.

Kuv ntxiv sau AnimationCreator siv JavaFX thiab Java3D.

Nws ua rau tsim thiab kho cov kev cai Animations yooj yim heev los ntawm kev muab qhov yooj yim nkag siab UI.

Koj tuaj yeem tsim, kho, hloov npe thiab rov teeb tsa Cov Duab rau 4x4x4, 6x6x6 lossis 8x8x8 LED Cubes

Txhawm rau tsim cov Animation tshiab yooj yim ntaus Cov Ntaub Ntawv> Tshiab, hauv qab "Cube" koj tuaj yeem xaiv lub Cube loj, los teeb Cov Xim ntawm LED xaiv cov xim uas koj xav tau nrog Cov xim xaiv nyob rau sab laug thiab tom qab ntawd nyem rau ntawm LEDs koj xav tau xim ntawd rau tus ncej ntawd. Txhawm rau ntxiv Lwm Tus Ntaus "Tom ntej" lossis "+". Tus so ntawm UI Kev Tswj yog qhov piav qhia tus kheej heev, lub npov nyob ib sab ntawm Cubes Layers yog txhawm rau txheeb xyuas Cov Txheej Txheem twg yuav tsum cuam tshuam los ntawm kev hloov pauv thiab "Khaws Ncej". Tsuas yog sim nws thiab koj yuav xam tawm txhua yam nyob rau hauv tsis muaj sijhawm.

Ib qho ntxiv los sim qhov Animation koj tuaj yeem nyem lub pob "View 3D" uas qhib lwm lub qhov rais nrog Java3D Qauv ntawm Lub Cube. Koj tuaj yeem tig lub Koob Yees Duab thaum tuav sab laug nas khawm (Nias R kom rov kho lub Koob Yees Duab). To ua si/ncua lub Animation ntaus P Key, kom rov pib ua Animation ntaus Q. TextField hauv qab "View 3D" buttondenotes tam sim no FrameTime, ua qhov nrawm ntawm koj qhov kev ua yeeb yaj kiab.

Thaum koj ua tiav nrog Animation muab nws lub npe thiab ntaus Cov Ntaub Ntawv> Txuag Raws li … thiab khaws cov Animation rau tib daim nplaub tshev zoo li Cubo_Control.ino Sketch.

Txhawm rau suav nrog koj cov Animation tshiab hauv Sketch qhib Cubo_Control.ino thiab ntxiv cov cai hauv qab no rau saum Sketch:

#suav nrog "RGBit.h" // Hloov

Nqes mus rau BTEvent () thiab ntxiv cov ntaub ntawv cov ntaub ntawv mus rau qhov hloov pauv-rooj plaub ntawm cov animations

hloov (curAnim) {

… Case 10: animation = & ani_cubesmove [0] [0]; FRAME_TIME = ANI_CUBESMOVE_FRAMTIME; maxCount = ANI_CUBESMOVE_FRAMES; tawg; rooj plaub 11: // KOJ YUAV TSUM NYEEM TSHIAB animation = & ani_rgbit [0] [0]; FRAME_TIME = RGBIT_FRAMETIME; maxCount = ANI_RGBIT_FRAMES; tawg; }

Kauj Ruam 13: Bluetooth App

Txhawm rau tswj lub Cube, ua tsaug rau HC-05 Module nws yooj yim heev los tsim Bluetooth app los txuas koj Xov Tooj rau Cube.

Txuas mus rau App: Github

Lub App tau qhib qhov chaw yog li xav tau ntxiv ntxiv Animations/nta koj tus kheej.

• Pib App, nws nug koj kom qhib Bluetooth
• Nyem "Tshawb nrhiav" thiab cov npe muaj Bluetooth sib txuas tshwm. Txheeb xyuas HC-05 Module los ntawm Cube thiab nyem rau ntawm nws.
• Yog tias muaj qhov ua yuam kev thaum sim txuas rau Lub Cube, sim ua khub HC-05 tus qauv hauv Bluetooth teeb tsa tus kheej
• Thaum txuas nrog App hloov mus rau Lub Vev Xaib Tswj thiab Bluetooth txuas tau tsim

Tswj

• Ceev & Ci ntsa iab: Hloov qhov ntsuas qhov ntsuas kom nrawm dua/qeeb Animation lossis hloov qhov ci ci
• Animations: Nyem rau ntawm lub pob kom hloov qhov Animation, los ntawm lub neej ntawd Animations tau rov ua dua (Pib los ntawm sab laug sab laug lub pob sib xws rau currAnim)
• Text Scroll: Nyem rau "Text" khawm uas coj los sib tham los nkag rau qee cov ntawv uas yuav raug nqes los ntawm lub voos xwmfab
• Hais kom ua: Koj tuaj yeem nkag mus ua lus txib tus kheej nrog Command TextField (saib mus rau hauv BTEvent () txoj kev ntawm Cubo_Control.ino rau syntax)
• Snake: Game Snake classic (liab: apple, ntsuab: nab Lub taub hau, xiav: sneak Tail) (Kev tswj: 4 lub khawm qhia, nce thiab nqis yog tshwm sim los ntawm kev xa Xov Tooj rau pem hauv ntej (Up) lossis rov qab (Down))
• Suab Visualizer: MSGEQ7 siv los pom 6 lub suab band los ntawm AUX Jack (Khawm rau Animation 7)
