Nyob zoo, phooj ywg.

Hauv kab lus no kuv yuav qhia koj yuav siv Led Matrix siv Arduino li cas.

Led Matrix yog sau los ntawm LEDs nyob rau hauv daim ntawv ntawm arrays. Led Matrices muaj ntau yam kab thiab kab, nyob ntawm hom. Los ntawm kev nthuav tawm ob peb LEDs nrog kev sib xyaw ua ke, Led matrix tuaj yeem tso saib tus lej cim, ntawv, cim, thiab lwm tus Lwm lub npe rau Led Matrix yog Dot Matrix.

Txoj haujlwm ua haujlwm ntawm Led Matrix zoo ib yam li "7-Segment Display" uas kuv tau tsim nag hmo. Qhov sib txawv ntawm ob yog daim ntawv ntawm qhov pom xwb.

Kauj Ruam 1: Cov Lus Qhia Tshwj Xeeb ntawm Led Matrix

Nov yog qhov tshwj xeeb ntawm Led Matrix:

• Cov LEDs: 64
• Tus naj npawb ntawm kab: 8
• Cov nab npawb: 8
• Ua haujlwm voltage: 4.7V - 5V DC
• Ua Haujlwm Tam Sim No: 320mA
• Max Ua Haujlwm Tam Sim No: 2A

Kauj Ruam 2: Cov Cheeb Tsam Xav Tau

Yuav tsum muaj cov khoom siv:

• Coj Matrik
• Arduino Nano Cov
• Jumper Hlau
• USBmini
• Pawg Thawj Coj

Yuav tsum muaj tsev qiv ntawv:

LedControl

Txhawm rau ntxiv lub tsev qiv ntawv rau Arduino IDE, koj tuaj yeem pom hauv kab lus no "Ntxiv Cov Tsev Qiv Ntawv rau Arduino"

Kauj Ruam 3: Txuas Led Matrix rau Arduino IDE

Saib cov lus piav qhia hauv qab no lossis saib daim duab saum toj no:

Coj Matrix rau Arduino

VCC ==> +5V

GND ==> GND

DIN ==> D6

CS ==> D7

CLK ==> D8

Kauj ruam 4: Programming

Nov yog qhov piv txwv piv txwv uas tuaj yeem siv los sim ua tus lej matrix:

// Peb ib txwm yuav tsum suav nrog lub tsev qiv ntawv#suav nrog "LedControl.h"

/*

Tam sim no peb xav tau LedControl los ua haujlwm nrog. ***** Cov lej tus lej no tej zaum yuav tsis ua haujlwm nrog koj lub khoos phis tawj ***** tus pin 6 txuas nrog rau DataIn tus pin 8 txuas nrog CLK tus pin 7 txuas nrog LOAD Peb tsuas muaj ib qho MAX72XX nkaus xwb. */
