Koj puas tau ua haujlwm nrog npaj ua 8x8 LED matrix raws li qhia? Lawv tuaj ntawm ntau qhov ntau thiab zoo heev los ua haujlwm nrog. Qhov loj tuaj yeem npaj tau loj yog nyob ib ncig ntawm 60mm x 60mm. Txawm li cas los xij, yog tias koj tab tom nrhiav rau qhov loj dua npaj tau ua LED matrix, koj yuav tsis muaj hmoo.

Txog qhov haujlwm no, peb yuav tsim ib lub xim loj loj LED matrix zaub uas yog ua los ntawm ob peb loj loj 8x8 LED 10mm matrix modules daisy-chained ua ke. Txhua ntawm cov 8x8 LED matrix modules no nyob ib puag ncig 100mm x 100mm loj.

Kauj Ruam 1: Tau PCB

Txhawm rau kom tau PCB koj tuaj yeem tsim nws ncaj qha rau PCBWAY, yuav ua li cas thiaj xaj tau yooj yim heev thiab koj yuav tau txais 10 Pcs PCB rau $ 5 nrog PCB zoo heev.

Kauj Ruam Kom Txiav:

1. SignUp/Nkag mus rau hauv pcbway.com

2. Qhib PCB qhov project txuas 8x8 BIG LED Matrix

3. Nyem Ntxiv rau lub laub

4. Yog tias pom lub npov "Thov sau rau txheej txheej ntawm saum toj mus rau hauv qab ntawm no" nyem kaw lub thawv sib tham.

5. Ntawm PCB Cov Lus Hais hauv nplooj ntawv xaiv qhov loj sau 100x100mm thiab hauv txheej txheej xaiv "2Layer", saib daim duab kom ntxaws.

Kauj Ruam 2: Yuav Tsum Muaj

Nov yog cov khoom uas koj yuav xav tau los ua qhov haujlwm no:

• (64) LED 10MM
• (1) IC MAX7219CWG (SMD)
• (1) R 10K OHM (SMD 0603)
• (1) C 0.1UF (SMD 0603)
• (1) C 47UF (SMD 1206)
• (1) 1X5 MALE PIN HEADER

Kauj ruam 3: Schematic

Kauj Ruam 4: Thawj Lub Sij Hawm Soldering LED D30

1. Txiav ob txhais ceg coj tsis pub dhau PCB sab nraum

2. Solder LED rau hauv PCB nrog lub npe D30.

Kauj Ruam 5: Cov Khoom Siv SMD Solder

Tom qab ua tiav qhov muag LED D30, tom qab ntawd txhuam tag nrho cov SMD Cheebtsam IC MAX7219CWG, R 10K ohms, C 0.1uf & 47uf.

Kauj Ruam 6: Txuas thiab Muab Tshuaj Txhuam Tag nrho LEDs

Nruab tag nrho cov LEDs uas tseem tshuav ntawm D1 txog D64.

Kauj Ruam 7: Txiav Tag Nrho Cov LED

Kauj Ruam 8: Solder Txiv Neej Tus Pin Header

Solder txiv neej tus pin header ntawm INPUT sab nraub qaum ntawm PCB.

Koj tuaj yeem txuas ib lossis ntau PCB los ua ntu, feem ntau yog 4 lossis 8, yog li koj tuaj yeem tsim lub rooj tsav xwm coj los coj ua cov ntawv nyeem. Txhawm rau txuas INPUT rau OUTPUT ib leeg los ntawm kev sib txuas tus txiv neej tus pin lub taub hau kaw ua ke, kev saib xyuas yuav tsum tau siv lub thav duab ntev nyob tom qab kom txhua PCB tuaj yeem ruaj ntseg los ntawm cov ntsia hlau.

Kauj Ruam 9: Xeem

Txhawm rau ntsuas nrawm, koj tuaj yeem siv Wemos D1 lub rooj tsavxwm me me los ntawm kev rub lub firmware siv ESP Matrix Offline App, tom qab ntawd txuas lub xov tooj ntawm PCB 8x8 BIG LED Matrix rau Wemo board (CLK rau D5, CS rau D6, DIN rau D7, VCC rau 5V & GND rau G)
