Kauj Ruam 3: Npaj Pawg Thawj Coj

1/8 fiberboard (hardboard, masonite, xijpeem koj xav hu nws) yog ob txhais taw los ntawm plaub ko taw raws li nws los ntawm lub khw. Kom meej meej peb yuav tsum coj nws los me me me me. Qhov zoo ntawm kev ua haujlwm nrog yam no ntawm lub rooj tsavxwm yog nws zoo li cov ntawv tuab thiab tuaj yeem txiav tau yooj yim nrog rab riam muaj txiaj ntsig. laj kab rau rab riam. Siv ob peb daim hla nrog rab riam, siv koj lub sijhawm, tsis muaj kev maj nrawm. Tshwj tsis yog tias koj yuav tsum ua tiav qhov no los ntawm Christmas thiab koj tseem tsis tau paub tias koj yuav tsum ua kom txog thaum txog lub Kaum Ob Hlis 16 … Tseem, koj cov ntiv tes muaj nqis ntau dua qhov phiaj xwm, yog li ceev faj!

Thaum koj tau txais lub rooj txiav tawm, tsoo cov npoo nrog koj cov ntawv lossis ntawv txhuam kom nws tsis ntse. Tiag tiag, cov khoom no muab cov ntawv txiav tsis zoo tshaj plaws … Tom qab ntawd ntsuas haum nws hauv koj tus ncej thiab ua cov ntaub ntawv/xuab zeb ntug raws li xav tau kom haum haum nrog tsuas yog qhov tsim nyog. Ib zaug ntxiv, siv koj lub sijhawm thiab ua kom haum rau thawj zaug. Nws nyuaj heev kom muab cov khoom ntoo rov qab rau ntawm daim uas tau txiav me me dhau.

Nyob ntawm kev tsim khoom zoo ntawm tus ncej koj tau txais koj yuav xav sim tsuas yog tig lub rooj tsavxwm ib puag ncig thiab pom yog tias nws haum rau lwm txoj kev. Kuv lub thav duab tsis yog plaub fab thiaj li ua kom yuam kev no ua haujlwm nrog qhov ua tsawg kawg. Yog tias koj pom koj tus cwj pwm zoo ib yam, nco ntsoov kos qhov kawg ntawm ob daim, nws yuav muaj teeb meem thaum nws los txog sijhawm los teeb thiab tho qhov lub qhov.

Tam sim no koj xav nqa cov ntawv ntsa uas koj luam tawm hauv cov kauj ruam kawg thiab muab tso rau saum koj daim ntawv fiberboard thiab muab nws ua kom tag nrho. Nws yuav tsum yog hais txog qhov loj me. Thaum nws tau kab, siv koj cov pokey ntse tshaj plaws txhawm rau txhawm rau los ntawm qhov nruab nrab (-ish) ntawm txhua lub teeb thiab muab qhov faib rau hauv fiberboard. Qhov kev faib tawm no yuav yog lub cim uas koj laum 5/16 qhov hauv lub rooj tsavxwm kom cov LEDs ci los ntawm. Yog tias koj twb tau txiav lub qhov muag teeb tawm ntawm daim ntawv ntsa koj tuaj yeem kwv yees qhov chaw laum lossis siv ib qho ntawm cov ntawv xeem. Kuv tau pom nws yooj yim me ntsis rau qhov muag qhov muag ntawm cov khoom no los ntawm kev kos lub voj voog me ntsis nyob ib ncig ntawm txhua qhov faib nrog tus xaum.

Lub sijhawm los ua qee cov chips. Siv cov cuab yeej laum twg los xij uas koj muaj thiab 5/16 "laum kom tso 26 qhov rau hauv pawg thawj coj saib. Kuv tus menyuam laum xovxwm yuav tsis tsoo lub qhov hauv nruab nrab … yog li kuv yuav tsum siv lwm lub tshuab ntaus nrig. Koj hais yog lawm, kuv lub qe me me yuav tsis tuav 5/16 "laum, tab sis nws yuav chuck li 9/32" zoo xwb;-) Lub qhov tshiab yuav tawg me ntsis yog li coj koj cov ntaub ntawv lossis ntawv txhuam thiab txhuam lawv cov ntug ib yam. LED yuav tsum tsuas yog haum los ntawm lub qhov kom PCB tso ncaj rau tom qab ntawm lub rooj tsavxwm.

Yog tias koj tseem tsis tau txiav cov qij tawm, tam sim no yog lub sijhawm. Tua tawm X-Acto riam thiab txiav ntoo thiab mus rau hauv nroog. Kuv tus tub hais tias txiav ib qho X duab rau hauv txhua lub teeb thiab tom qab ntawd txiav tawm cov duab peb sab uas ua haujlwm tau zoo.

Kauj Ruam 4: Muab qee Cov Sparkles tso rau hauv

Nws yog lub sijhawm los pib LED qhov kawg ntawm txoj haujlwm no. Txiav tawm 26 ntawm WS2812Bs thiab kab lawv ntawm lub rooj tsavxwm. Koj xav kom ntseeg tau tias lawv txhua tus pw ncaj. Qhov no kuj yog lub sijhawm zoo los sim lawv txhua tus zuj zus ua ntej yuav muag tag nrho pawg kom pom tias muaj ib qho yeej nyob rau ntawd. Kuv tau txuas qhov yooj yim Arduino kos duab uas tsuas yog spits tawm xim xim hauv WS2812-hais lus. Koj tuaj yeem siv lub cable servo, lossis kab xov txuas, lossis cov xaim xaim xaim uas koj yuav muaj nyob ib puag ncig txhawm rau txhawm rau ntsuas kab. Tsuas yog lo 3-pin me ntsis ntawm tus pin header rau hauv kab thiab koj tuaj yeem tuav qhov ntawd ntawm "hauv" pawm ntawm LEDs 'PCBs. Txhua LED yuav tsum teeb pom kev, thiab tsuav yog koj tsuas yog kuaj ib zaug xwb Arduino lub zog muab khoom tuaj yeem ua haujlwm tau yooj yim.

Thaum koj paub tseeb tias txhua lub LEDs tau ua haujlwm tau zoo koj tuaj yeem pib ua cov xov hlau. Kuv tsuas yog siv qee qhov qub 20 ntsuas ntsuas tso tseg hlau txuas kuv tau txais thaum Xov Tooj Cua Shack tseem nyob ib puag ncig. Koj yuav tsum ua 23 txhua qhov liab, dub, thiab ntsuab, lossis xim twg koj xav siv rau lub zog, hauv av, thiab cov ntaub ntawv. Kuv tsis muaj qhov ntev los muab qhov ntev ntawm cov xov hlau. Kuv nyuam qhuav tuav ib daim hlau ntawm ob peb LEDs thiab pib txiav pawg mus txog qhov ntev ntawd. Muaj ob peb tus nyob hauv nruab nrab uas zoo li ntev me ntsis dua li lwm tus, yog li khaws qhov muag rau qhov ntawd.

Tom qab koj cov xov hlau raug txiav mus tom ntej thiab hle me ntsis los ntawm txhua qhov kawg, tsuas yog txaus kom yaj mus rau cov pawm ntawm PCBs. Peb yuav tsis txuas H rau kuv, lossis Q rau R tam sim no. Tua qhov kawg ntawm cov xov hlau, thiab xaum cov ntaub qhwv ntawm LEDs. Tom qab ntawd npaj rau cov txheej txheem uas nyuaj rau hu nkauj lub ntsis ntiv tes thiab muab cov xov hlau txuas rau hauv PCBs. Rov ua qhov zoo li kaum ib txhiab lub sijhawm, txawm tias nws zoo li 155 thaum kawg.

Tom qab koj tau txais tag nrho peb kab uas tau muag lawm, koj yuav tso cov ntaub ntawv xov hlau ntev los ntawm H mus rau kuv, tom qab ntawd los ntawm Q rau R., yog li A, kuv, thiab R txhua tus muaj lawv tus kheej cov xov hluav taws xob. Saib daim duab thiab cov duab thiab nws yuav ua rau txhua tus nkag siab. Koj tseem yuav tso ib qho ntawm 1000μF lub kaus mom rau lwm qhov kawg ntawm txhua kab, ntawm H, Q, thiab Z, kom khaws lub zog cia rau txhua txoj hlua. (Kuv tsis tuaj yeem cog lus tias nws tsim nyog, tab sis nws paub tseeb tias tsis ua mob dab tsi.) Thaum kawg koj yuav ua lub jumper hlau los ntawm A cov ntaub ntawv hauv ncoo uas yuav mus rau Arduino. Tsuas yog siv lub jumper ib txwm thiab txiav nws hauv nruab nrab, tom qab ntawd solder R1, 220 txog 470 Ohm resistor, inline thiab npog nrog cua sov ntsws. Cov laug ib sab rau DIN ncoo ntawm thawj LED, thiab lwm qhov kawg mus rau Arduino tus pin 6 (nws tsis tas yuav yog 6, nws tuaj yeem yog tus pin tiag tiag).

Thaum koj tau txais tag nrho koj cov LEDs ua ke ua ke, thiab cov xov hluav taws xob txuas ntawm ib kawg ntawm txhua kab, thiab cov khoom sib txuas ntawm lwm qhov, nws yog lub sijhawm mus tom ntej thiab kub kua nplaum txhua yam rau hauv pawg thawj coj saib. Siv koj lub sijhawm, tsis txhob txhuam koj cov ntiv tes rau ntawm lub rooj tsavxwm. Kuv siv zoo li peb lossis plaub daim nplaum lo kom ntseeg tau tias txhua yam nyob qhov twg kuv tso nws, suav nrog txhim kho me ntsis ib ncig ntawm cov khoom siv hluav taws xob thiab cov xov hluav taws xob los ua kom muaj zog.

Koj yuav pom ob lub rooj sib txawv sib txawv hauv cov duab. Ib qho muaj Arduino Pro Mini thiab HC-05 Bluetooth module, lwm qhov muaj, zoo, tseem tsis tau muaj dab tsi. Ib qho nrog Pro Mini yog qhov uas tau mus rau kuv tus ntxhais xeeb ntxwv uas kuv tsis tau txais cov duab tsim txaus. Nws tseem yog ib qho uas tau piav qhia hauv kab ntawv txuas nrog. Qhov faib hluav taws xob uas txo qis Arduino's 5v TX mus rau HC-05's 3.3v RX tsuas yog tsim rau hauv kab uas txuas ob. Koj tuaj yeem tsuas yog kaw qhov xaim thiab txuas R2, tus tiv thaiv 1k7, hauv kab. Tom qab ntawd txuas R3, 3k3 resistor, los ntawm HC-05 kawg ntawm R2 mus rau xaim mus rau hauv av. Lossis koj tuaj yeem tsim qhov ntawd mus rau tus protoboard yog tias koj xav tau.

Lwm lub rooj tsavxwm hauv cov duab yog kuv li thiab yuav siv Raspberry Pi Zero W hloov chaw ntawm HC-05. Arduino ib qho muaj lub rooj tsav xwm faib hluav taws xob kuv khob ua ke ntawm tus tiv thaiv kab thaiv. Nws tsuas yog ob peb kab ntawm lub taub hau thiab lwm 1000µF lub tshuab hluav taws xob txuas mus rau lub zog txuas hluav taws xob. Kuv tawm tshiab ntawm lub hwj chim cable jack zoo li ntawd rau Pi version yog li kuv tsuas yog tau txais yam zoo nrog cov ntsia hlau txuas ntawm qhov kawg thiab ntsia tag nrho lub zog ua rau qhov ntawd. Kuv yuav zaum tsim lub tsev kom zoo me ntsis, thiab kuv yuav xaus ntxiv qhov 1000µF cap ib yam.

Kauj Ruam 5: Muab Nws Qee Qhov Ntsej Muag - Txoj Kev Arduino

Tam sim no ib feem peb txhua tus tau tos, ua rau nws ua tau ib yam dab tsi. Hmoov zoo rau koj Kuv twb tau siv ob peb hmo dhau los sau cov cai rau txoj haujlwm no. Txhua yam koj yuav tsum tau ua yog rub tawm cov ntawv zip, rho tawm nws rau koj lub khoos phis tawj qhov twg, qhib nws hauv Arduino IDE, thiab xa nws mus rau koj Arduino. Hmoov zoo rau kuv kuv yog hmo ntuj, hmo lig tsis yog qhov loj (nws yog 4 teev sawv ntxov thaum kuv sau qhov no).

Arduino qhov kawg ntawm qhov no yeej yog rau daim ntawv hauv daim nplaub tshev npe "rudLightsArduino." Cov ntaub ntawv zip uas muaj lawv tau txuas nrog cov kauj ruam no. Xwb, koj tuaj yeem tau txais nws los ntawm GitHub chaw cia khoom. Txawm li cas los xij koj txiav txim siab kom tau txais cov ntaub ntawv, ib zaug lawv nyob hauv koj lub computer qhib rudLightsArduino.ino hauv Arduino IDE. Uas yuav tsum thauj tsib lwm cov ntaub ntawv raws li tabs hauv IDE ib yam. Yog tias koj txuas koj li WS2812B LED cov ntaub ntawv tus pin rau Arduino tus pin uas tsis yog tus pin 6 koj yuav xav nrhiav kab "#define LED_PIN 6" thiab hloov 6 rau tus pin koj siv.

Tom qab ntawd koj tuaj yeem hloov mus rau lub tab uas sau tias "daVars.h" thiab nrhiav ib feem rau cov hlua nyuaj uas tau nthuav tawm ntawm lub rooj tsavxwm. Cov no yog cov kab pib nrog "const char string_X PROGMEM blah blah" ze rau saum cov ntaub ntawv. Hloov cov no raws li xav tau, tsuas yog xyuas kom lawv yog txhua tus CAPs thiab tsis muaj cov cim tshwj xeeb (zoo li lub sijhawm, tus lej, thiab lwm yam …) Qhov chaw zoo xwb.

Koj tuaj yeem ntxiv kab ntau ntxiv los ntawm kev luam kab uas twb muaj lawm, muab nws tso rau hauv qab ntawm lwm tus, thiab hloov tus lej hauv ntu "string_X ". Tsuas yog nce tus lej txhua lub sijhawm. Koj tuaj yeem kwv yees kwv yees ntau kab raws li yuav haum rau hauv Arduino lub flash cia. Cov txuj ci tseem ceeb ntawm PROGMEM ib feem txhais tau tias cov hlua no tsis yog txhua qhov khaws cia hauv RAM, lawv tau nyeem ncaj qha los ntawm lub cim xeeb flash xwb. Kuv yuav tsis nkag mus ntxiv, tab sis koj tuaj yeem kawm paub ntau ntxiv ntawm Arduino nplooj ntawv siv. Thaum koj ntxiv lossis tshem tawm kab nyob ntawd koj yuav tsum tau hloov kho ob peb ntu ib yam nkaus. Nrhiav ntu txuas ntxiv nrog "ref table rau cov hlua saum toj no" thiab ntxiv/tshem tawm "string_X" raws li xav tau los ntawm nruab nrab ntawm {kab zauv kab}. Thaum kawg, nrhiav kab "int string_count = X" thiab hloov tus lej kom yog cov hlua ntawm cov lus saum toj no. Tus lej no yog suav qhov tseeb, piv txwv li tsis pib ntawm xoom. Yog tias muaj xya "const char string_X" kab ces muab 7 ntawm no.

Tam sim no suav thiab xa cov cai rau koj Arduino. Koj yuav tsum tau txiav tawm HC-05 txhawm rau ua li ntawd raws li Bluetooth module siv tib TX/RX kab ib yam li khoos phis tawj-> Arduino cov cuab yeej tsim khoom. Tom qab tus lej tau muab tso rau, tshem tawm 'duino los ntawm lub khoos phis tawj thiab rov txuas koj li BT module.

Tam sim no koj tuaj yeem thaum kawg sib sau cov pawg uas mus rau hauv tus ncej. Cov iav ua ntej, tom qab ntawd cov duab tsis zoo nrog lub teeb txiav tawm. Tom ntej no los ob daim ntawv ntawm vellum ua lub diffuser. Kuv tau xaus ntxiv lwm txheej ntawm kev nthuav tawm los ntawm lo ib daim ntawv ntawm cov ntawv luam ntawv ib txwm nyob hauv ib yam. Thaum kawg koj tuaj yeem tso daim ntawv fiberboard puv ntawm cov khoom zoo rau hauv tus thav duab, ua kom ntseeg tau tias nws tau qhia ncaj ncees rau daim ntawv ntsa.

Dab tsi los tom ntej nyob ntawm qhov koj tau siv rau lub thav duab, thiab yuav ua li cas cov khoom ua tau zoo nyob hauv cov kab ntawd. Koj tuaj yeem pom hauv daim duab ntawm qhov ua tiav ib qho uas kuv yuav tsum tsim kev txuas mus rau lub thav duab kom muaj qhov siab ntxiv ntawm txhua yam. Qhov txuas ntxiv no tsuas yog 1/2 los ntawm 3/4 ntoo thuv sawb, mitered ntawm cov ces kaum, thiab glued mus rau tom qab ntawm tus ncej nrog ntoo kua nplaum. Tom qab ntawd kuv tau siv qee daim duab me me uas zoo li daim duab ntawm daim txiag ntoo los ua lub ntsej muag sab hauv lub thav duab uas tuav hauv qhov thaub qab. Rau cov uas kuv glued qee qhov sawv ntsug ntawm cov ntoo thuv los tsim lawv tawm mus rau sab nraub qaum ntawm tus thav duab txuas ntxiv. Tom qab ntawd kuv tau drilled qee qhov kev sim tsav thiab rub lub thav duab qub thaub qab mus rau qhov tsis pom kev. Thaum kawg kuv tsav-drilled thiab ntsia qhov ntev ntawm cov hlua txuas txuas mus rau tus ncej txuas ntxiv los ua tus khuam khawb ncaws. Yog tias koj siv lub thawv duab ntxoov ntxoo lossis lub thav duab tuab koj yuav tsis tas yuav hla txhua qhov kev lom zem ntxiv no.

Thaum kawg kawg, ntxeev nws thiab ntsaws rau hauv AC adapter thiab saib lub teeb pom kev pib. Thaum kuv tus ntxhais thawj zaug ntsaws nws hauv nws ntsais tawm "Zoo siab heev Christmas." Koj li yuav sau kab ntawv twg los xij koj muab tso rau hauv "const char string_0 " lossis "RUDLIGHTS ALPHABET BOARD" yog tias koj tseem tsis tau hloov pauv txoj cai.

Yog tias koj hla HC-05 Bluetooth module ib feem ntawm qhov no, nrog koj zoo siab, koj ua tiav! Kuv vam tias koj tau txais ntau mais ntawm koj kev sib tham nrog Upside Down:-)

Yog tias koj mus rau Bluetooth tus qauv, mus rau kauj ruam tom ntej rau, qhov kuv ntseeg yog, qhov txias, thiab vim li cas kuv thiaj li pib ua txoj haujlwm no es tsis yog yuav kuv tus ntxhais xeeb ntxwv lwm tus menyuam roj hmab.

Kauj ruam 6: App (!)

Yog, koj nyeem qhov yog. Muaj tus khub Android app rau rudLights uas tso cai rau koj los tso saib, thiab txawm tias txuag, kev cai cov lus ntawm koj lub rooj tsavxwm. Christmas kawg peb tau muab kuv tus ntxhais xeeb ntxwv tso rau Amazon Fire ntsiav tshuaj. Yog li ib qho ntawm cov ntsiab lus tseem ceeb ntawm txoj haujlwm no yog kom muaj txoj hauv kev rau nws siv lub ntsiav tshuaj ntawd los cuam tshuam nrog rudLights Alphabet Board. Kuv tau xaus ntawm Thunkable uas tau muab txoj hauv kev zoo, yooj yim ntawm kev tsim app rau tus txiv leej tub uas tsis tau ua Android app ua ntej. Kuv tswj hwm los ua ke ib yam uas ua txhua yam kuv xav tau hauv ob peb hnub xwb. Koj tsis tas yuav ua li ntawd, koj tsuas tuaj yeem rub tawm lub app los ntawm kuv tus neeg rau zaub mov lossis GitHub chaw cia khoom. Los ntawm ib qho chaw twg koj tseem tuaj yeem rub lub app txoj haujlwm.aia cov ntaub ntawv uas koj tuaj yeem siv ntawm Thunkable los ua koj tus kheej version ntawm rudLights App. Xav tias dawb los yog tshem tawm ib yam dab tsi, rov tsim dua, hloov cov duab, koj muaj dab tsi.
