Vim li cas koj thiaj xav saib cov duab me me lossis cov me me LCD yog tias koj tuaj yeem ua nws loj?

Nov yog cov lus piav qhia ib kauj ruam ntawm yuav ua li cas tsim koj tus kheej Giant sized Spectrum analyzer.

Siv cov vuas luaj acrylic thiab coj kab txaij los tsim chav ua kom pom lub teeb pom kev siv 280+ qhov loj me ntawm LED

Vim li cas nws me me yog tias koj tuaj yeem ua nws loj ….

Khoom siv

Koj yuav xav tau arduino Mega, pheej yig zaus board SI5351 thiab puv tes ntawm qee qhov me me.

Cia peb pib

Kauj ruam 1: Taw qhia

• 40Hz - 16Khz
• Kab hauv
• Microphone hauv
• Hom sib txawv thiab xim
• Tswj lub teeb
• Tswj kev nkag siab
• Ncov ncua kev tswj

Cov khoom tseem ceeb:

• Arduino Mega 2560 Pro
• Si5351A pawg thawj coj tawm
• WS2812 (74Leds/meter)
• Acryl 10 hli

Koj yuav xav tau kev nkag mus rau lub tshuab txiav laser kom txiav tawm tag nrho 280 pobzeb acrylic lossis koj yuav tau muab tso rau hauv mais ntxiv los ua txhua yam ntawm tes.

Txoj haujlwm rub tawm: Txhua yam khoom siv kho vajtse, software thiab lwm yam yog "raws li yog" thiab koj tuaj yeem hloov kho nws raws li koj xav tau. Tsis muaj ib qho ntawm cov khoom siv tau raug sim rau CE ua raws thiab lwm yam. Yog tias koj txiav txim siab siv ib yam dab tsi los ntawm kev tsim qauv no, koj ua li ntawd ntawm koj tus kheej txoj kev pheej hmoo. Coding, PCB thiab cov duab kos yog muaj rau rub tawm. Yog tias koj nyiam txoj haujlwm no, thov qhia cov vis dis aus no rau koj cov phooj ywg thiab tsis txhob hnov qab nyem lub pob zoo li thiab sau npe yuav!

Nws ua haujlwm li cas

Muaj ob lub microcontrollers koom nrog tab sis ib qho yog xaiv tau vim tias nws tau siv rau lub logo flashing nkaus xwb.

Lub hauv paus tseem ceeb hloov pauv ib puag ncig Arduino Mega 2560 (Pro version nyiam vim tias hneev taw me dua). Arduino siv lub rooj sib tham zaus SI5351 los tsim ob qho kev sib txawv ntawm qhov sib txawv. Txhua zaus siv los tsav lub moos ntawm lub tshuab hluav taws xob MSGEQ7. MSGEQ7 yog 7 channel spectrum analyzer nti uas faib cov teeb liab nkag mus rau hauv 7 qhov sib txawv ntim. Nyob ntawm cov tswv yim, cov teeb liab tso tawm ntawm txhua lub thawv sib txawv. Txhua lub ntim ntim tau xa mus rau cov chips tawm DAC qhov uas lawv tau nthuav tawm ib ntu dhau ib qho. Vim tias nws yog 7 channel nti, kev dag yog siv los sab hauv hloov pauv ntau zaus ntawm cov ntim los ntawm kev hloov lub moos zaus ntawm cov nti ntawd.

Yog tias koj xav tau cov ntaub ntawv ntau ntxiv txog yuav ua li cas, cov ntaub ntawv ntau ntxiv muaj nyob hauv youtube.

Arduino nyeem DAC ntawm MSGEQ7 chips tas li thiab txhais cov ntim khoom rau tus lej ntawm ib lub teeb rau ib tus pej thuam acrylic. Cov leds no tau tsav ua ntu tab sis tseem nrawm txaus, txawm tias muaj 240 leds!

Kauj Ruam 2: Sau Koj Qhov

PCB cov

Hloov tshiab: TSHIAB TSHIAB VERSION HAUV NO:

tam sim no version muaj nrog ua ntej ua ke SMD cov khoom

Cov ntaub ntawv Gerber suav nrog hauv Cov Lus Qhia no. Xav tias dawb siv lawv los xaj koj tus kheej PCB rau lwm qhov.

Koj lub Cheebtsam tseem ceeb yog

• Arduino Mega 2560 Pro
• Si5351A pawg thawj coj tawm
• WS2812 (74Leds/meter) coj kab
• Acryl 10 hli
• MSgEQ7 nti

Thawj peb yam uas kuv tau txais los ntawm alieexpress thiab txheeb cov vev xaib zoo ib yam. Nws yuav siv sijhawm qee lub sijhawm nws yuav xa tawm tab sis nws yuav txuag koj qee cov nyiaj.

Cov acryl uas kuv siv los ua cov vuas, Kuv yuav hauv zos.

Rau IC's MSGEQ7 ceeb toom !!! Kuv xaj ob peb chav los ntawm sib txawv (Tuam Tshoj) thiab cov muag hauv zos tab sis tsis muaj ib qho ntawm cov ua haujlwm. Qhov kuv tau xaj los ntawm Mouser (Sparkfun) qhov twg tsuas yog ib qho uas ua haujlwm. Yog li, yuav ntse raws li koj tuaj yeem siv koj cov nyiaj ib zaug.

Kauj Ruam 3: Siv Breadboard lossis Txais PCB

Txawm hais tias kuv tau tsim PCB rau kuv teeb tsa, koj tseem tuaj yeem txiav txim siab siv lub khob cij yooj yim ntawm kev teeb tsa simular.

Yog tias koj xav tau, koj tuaj yeem xaj koj lub pcb ntawm koj tus neeg xa khoom. Cov ntaub ntawv gerber kom xaj nws suav nrog. Kuv xaj kuv li ntawm

JLCPCB.com

Xijpeem teeb tsa koj tab tom siv, xyuas kom tseeb tias koj muab tshuaj txhuam ntawm cov khoom siv kom raug.

PCB txheej txheem thiab cov npe khoom siv rau pcb suav nrog

Kauj Ruam 4: Ua Haujlwm Txhua Yam

Yeej, Nws yog qhov nrug nruab nrab ntawm cov leds ntawm daim kab xev uas ua kom qhov loj me ntawm cov vuas koj xav siv. Yog tias koj xav tau cov vuas loj dua ntawm qhov sib nrug ntxiv, koj yuav tsum tau txais cov kab ntawv sib txawv lossis txiav nws sib nrug thiab rov ua dua.

Hauv kev xav, koj tuaj yeem ua kom koj teeb tsa siab npaum li lub tsev koj nyob hauv txawm hais tias kev txuas xov tooj tuaj yeem dhau los ua qhov teeb meem hauv qhov xwm txheej ntawd. Kuv teeb tsa yog li 50cm hauv qhov siab thiab nws yog 82cm dav. Qhov ntawd yog qhov loj dua li lub vijtsam me me ntawm kuv lub mp3 player! Kuv zoo super loj nws!

Xijpeem, Kuv tau siv cov tub ntxhais kawm ntawv ntawm autocad uas muaj pub dawb tom qab sau npe. Cov ntaub ntawv suav nrog. Koj yuav tau hloov kho lawv rau koj teeb tsa tab sis nws yuav ua rau koj pib paub tseeb.

Kuv siv kuv lub tuam txhab lub tshuab txiav laser los ua cov vuas tab sis yog tias koj muaj sijhawm txaus ntawm koj txhais tes, koj tuaj yeem ua nws ntawm tes …

Kauj Ruam 5: Muab Nws Txhua Qhov Ua Ke

Muab nws tag nrho ua ke feem ntau muab faib ua:

1. sib dhos ntawm cov yees acrylic suav nrog. cov ledstrips

2. sib dhos ntawm lub hauv paus

3. sib dhos ntawm lub logo ledstrip (yeem)

4. sib dhos ntawm cov yees mus raws

5. thaiv tag nrho cov kab ke

Txhua yam no yog qhov zoo tshaj plaws hauv youtube video

Hloov tshiab:

Tshiab version ntawm firmware muaj. Nws suav nrog hom kev debug los ntsuas cov cuab yeej:

Kauj ruam 6: Coding

Tus lej tseem ceeb nws daim duab txuas nrog.

Yog tias koj siv lub cim flashing, koj tuaj yeem siv logoblink los ua haujlwm me me arduino

Hloov tshiab !! Raws li ntawm version 2.0 ntawm PCB, ntxiv arduino Tiny rau lub logo tsis xav tau ntxiv lawm.

Ib qho ntxiv tso tawm muaj thiab tuaj yeem txuas ncaj qha rau lub logo ledstrip

Kauj Ruam 7: Txaus Siab Qhia Nws Rau Koj Cov Phooj Ywg

Tom qab muab txhua lo lus nyuaj no koj yuav tsum qhia nws rau lub ntiaj teb! Qhia rau koj cov phooj ywg txog nws thiab tsis txhob hnov qab qhia nws tawm hauv is taws nem.

Ua tibzoo saib kuv cov vis dis aus kom pom tias kuv tsim thiab tsim nws li cas.
