Aiki 1 – Saitunan Lamba (Matsa Dijital da Zuciya)

Katin cikakken zanen da ke gudanar da Project 1 ana loda shi kai tsaye a ƙarƙashin wannan labarin a gidan yanar gizon. A nan muna mai da hankali ne kawai kan mahimman saitunan da kuke iya canzawa: pin, adadin pixels, haske, launi, da saurin motsi. Ga animation na zuciya kuma muna nuna yadda ake sarrafa launi da kuma ko zuciyar tana da ƙarfi ko kuma an zana ta kawai.

LED Pin da Adadin Pixels

A wannan module, matrix 8×8 RGB an haɗa shi da GPIO 14 na ESP32-S3. Jimillar adadin pixels shine 64 (8 × 8). A cikin code ɗinku, ya kamata ku ga wani abu mai kama da wannan:

 
// Pin da aka haɗa da matrix 8×8 RGB 
const int MATRIX_PIN = 14;
 // dole ne ya zama 14 akan wannan module 
// Jimillar adadin LEDs (matrix 8 × 8) 
const int NUMPIXELS = 64; // canza kawai idan kuna amfani da girman matrix daban

Idan da gangan kuka bar NUMPIXELS a 16 (daga ainihin misalin NeoPixel), kashi ɗaya cikin huɗu na matrix kawai za a yi amfani da shi kuma animation ba zai cika dukkan allo 8×8 ba.

Tsarin Launi da Nau'in LED

Daban-daban na LED strips da matrices na iya amfani da tsarin launi daban-daban (misali, GRB maimakon RGB). Matrix ɗin da ke kan wannan board yana tsammanin tsarin RGB. A cikin maginin NeoPixel ko NeoMatrix, tabbatar da cewa an saita nau'in launi daidai:


 // Misali na abu mai kama da NeoPixel: 
Adafruit_NeoPixel pixels( NUMPIXELS, MATRIX_PIN, NEO_RGB + NEO_KHZ800 // tabbatar da wannan ya dace da tsarin launi na matrix );

Idan kun lura cewa ja da kore an musanya su akan nuni, duba wannan layin da farko kuma gyara tsarin launi.

Saurin Animation (Jinkiri Tsakanin Matakai)

Saurin motsin digo yawanci ana sarrafa shi ne ta hanyar ƙimar jinkiri mai sauƙi a milliseconds. Ƙaramin jinkiri yana nufin saurin motsi; babban jinkiri yana nufin jinkirin motsi. Nemi wani canji mai kama da:

 
// Jinkiri tsakanin motsin digo (a milliseconds)
 int dotDelayMs = 50; // 50 ms yana da sauri sosai

Gyare-gyare na yau da kullun:

Saita dotDelayMs = 20; don digo mai motsi da sauri sosai.
Saita dotDelayMs = 100; ko sama da haka don motsi mai jinkiri, mai natsuwa.

A cikin aikin loop(), wannan ƙimar yawanci ana wucewa zuwa delay(dotDelayMs); bayan kowane sabunta frame.

Launin Digo da Haske

Launin RGB na digo mai motsi ana sarrafa shi ne ta hanyar ƙimomi uku a cikin kewayon 0–255 (ja, kore, shuɗi). Misali:

 
// Launin digo (R, G, B) daga 0–255 uint8_t dotRed = 255; // cikakken ja 
uint8_t dotGreen = 0; // babu kore 
uint8_t dotBlue = 0; // babu shuɗi

Wannan zai samar da digo mai haske ja. Wasu haɗuwa masu amfani:

Ja zalla: (255, 0, 0)
Kore zalla: (0, 255, 0)
Shuɗi zalla: (0, 0, 255)
Rawayen: (255, 255, 0)
Fari: (255, 255, 255)

Hasken gabaɗaya yawanci ana sarrafa shi ne ta hanyar aikin haske daban:

 
// Hasken matrix gabaɗaya (0–255) 
uint8_t matrixBrightness = 40; // kiyaye shi ƙasa don guje wa ƙyalli mai yawa // A cikin setup(): matrix.setBrightness(matrixBrightness);

Ƙimar kusan 30–60 yawanci tana da kyau don amfani a cikin gida.

Saitunan Siffar Zuciya

Baya ga digo mai motsi, kuna iya nuna ƙaramin zuciya akan matrix lokacin da board ɗin ya fara kunna. Code ɗin misalin labarin (wanda aka loda a ƙasa) ya haɗa da saituna masu kama da:

 
// Launin zuciya (zuciya mai ƙarfi) 
uint8_t heartRed = 255; 
uint8_t heartGreen = 0; 
uint8_t heartBlue = 0; 
// Na zaɓi: yanayin bakan gizo ko zane kawai 
bool showOutlinedHeart = false; 
// gaskiya = zane kawai 
bool useRainbowHeart = false; 
// gaskiya = canza launuka akan lokaci

Amfani na yau da kullun:

Saita showOutlinedHeart = false; da useRainbowHeart = false; don zuciya mai ƙarfi ja.
Saita showOutlinedHeart = true; don nuna zanen zuciya kawai.
Saita useRainbowHeart = true; don ci gaba da canza launin zuciya ta hanyar tasirin bakan gizo.

Ana zana zuciyar ta amfani da ayyukan haɗin gwiwar NeoMatrix a cikin code ɗin da ke ƙarƙashin labarin. Kuna buƙatar canza canje-canjen da ke sama kawai don keɓance kamanninsa.

Taƙaitawa

Project 1 yana ba ku mafari mai sauƙi amma mai ƙarfi tare da ESP32-S3 RGB LED Matrix: kuna koyon yadda ake magance dukkan pixels 64, sarrafa launi, daidaita haske, da saita saurin motsi. Kuna kuma ganin yadda yake da sauƙi a canza daga digo mai motsi zuwa zuciya mai tsaye ko mai motsi akan wannan hardware ɗin.

Tabbatar da kallon cikakken bidiyon da aka saka akan wannan shafin don cikakken nunin mataki-mataki na motsin digo da animations na zuciya, tare da sauran ayyuka biyar. Cikakken code ɗin tushe yana samuwa a ƙarƙashin wannan labarin, kuma kuna iya tallafawa ayyukan gaba ta hanyar siyan module ɗin ta hanyar hanyoyin haɗin affiliate da aka jera a ƙarƙashin sashin code.
