Mashruuca Saacadda Shabakadda ee LED Matrix RGB ee ESP32-S3 - 3 Midab Habeen ah oo leh Taariikh

SaaS-ga S3 RGB NeoMatrix Internet Clock oo leh Iftiinka Maalinta/Habeenka Tooska ah

Mashruucani waa SaaS-ga S3 RGB Matrix Internet Clock kaas oo si toos ah u hagaajiya iftiinka maalinta iyo habeenkii. SaaS-ga S3 wuxuu ku xidhmaa Wi-Fi, wuxuu la midaynayaa waqtiga hadda jira ee NTP server, wuxuuna ku wareejiyaa waqtiga qaabka HH:MM ee 8×8 RGB NeoMatrix. Saacaddu waxay sidoo kale taageertaa midabbo RGB go'an ama wareegaya oo loogu talagalay qoraalka bandhigga.

Waxa saacaddani samayso

Ka dib marka la shido, SaaS-ga S3 wuxuu ku xidhmaa shabakaddaada Wi-Fi wuxuuna ka soo qaadaa waqtiga maxalliga ah ee hadda jira internetka. Waqtigu wuxuu si habsami leh ugu wareegayaa matrix-ka LED. Saacadaha habeenkii, bandhigu wuxuu si toos ah u yareeyaa iftiinka, halka maalintii uu dib ugu noqdo heer iftiin sare ah.

Maktabadaha la isticmaalay

Sketch-kani wuxuu isticmaalaa maktabadahan soo socda:

#include <WiFi.h>
#include "time.h"
#include <Adafruit_GFX.h>
#include <Adafruit_NeoMatrix.h>
#include <Adafruit_NeoPixel.h>

Ku rakib Adafruit NeoMatrix oo ka yimid Arduino Library Manager. Dhammaan ku-tiirsanaanta loo baahan yahay sida Adafruit GFX Library iyo Adafruit NeoPixel si toos ah ayaa loo rakibi doonaa.

Qaabaynta isticmaalaha ee muhiimka ah

Wi-Fi SSID iyo password (xarfaha waaweyn iyo kuwa yar)

Ku beddel qiimaha soo socda aqoonsigaaga Wi-Fi:

const char* WIFI_SSID     = "WiFi";
const char* WIFI_PASSWORD = "passW0rd";

Muhiim: Wi-Fi SSIDs waa xarfaha waaweyn iyo kuwa yar. SSID lagu magacaabo "Book" ma aha mid la mid ah "book". Haddii xarfaha waaweyn aan si sax ah u qoran, SaaS-ga wuxuu ku guuldareysan doonaa inuu ku xidhmaa.

NTP server, time zone, iyo daylight saving

Saacaddu waxay waqtiga ku midaynaysaa iyadoo la isticmaalayo NTP server-ka soo socda:

const char* ntpServer = "pool.ntp.org";

Waqtiga maxalliga ah waxaa lagu xisaabiyaa iyadoo la isticmaalayo offsets-yadan:

const long  gmtOffset_sec     = -5 * 3600; 
const int   daylightOffset_sec = 3600;

• gmtOffset_sec wuxuu qeexayaa UTC offset-kaaga ilbiriqsi
• daylightOffset_sec wuxuu ku darayaa saacad marka daylight saving time uu shaqeeyo (isticmaal 0 haddii aan loo baahnayn)

Qiimahaan waxaa lagu dabaqayaa:

configTime(gmtOffset_sec, daylightOffset_sec, ntpServer);

Iftiinka maalinta/habeenka tooska ah

Iftiinka bandhiggu wuxuu si toos ah isu beddelaa iyadoo ku xidhan saacadda hadda jirta:

const int DAY_BRIGHTNESS = 40;
const int NIGHT_BRIGHTNESS = 5;
const int NIGHT_START_HOUR = 22; // 10 PM
const int NIGHT_END_HOUR = 6;    // 6 AM

Inta u dhaxaysa 10 PM iyo 6 AM, iftiinka matrix-ka waa la yareeyaa si looga dhigo mid ku habboon jawiga mugdiga ah. Marka ka baxsan saacadahaan, iftiinka buuxa ee maalintii waa la soo celiyaa. Waxaad hagaajin kartaa qiimahaan si ay ugu habboonaadaan iftiinka qolkaaga.

Qaabaynta midabka RGB

Midabka qoraalka saacaddu waxaa lagu qeexayaa iyadoo la isticmaalayo qiimayaasha RGB (Red, Green, Blue), halkaas oo kanaal kastaa uu u dhexeeyo 0 ilaa 255. Midabbo badan ayaa lagu kaydin karaa array-ga waxaana si toos ah loo wareejin karaa:

uint8_t userColors[][3] = {
  {17, 43, 171},  // Light Blue
  {255, 0, 0},    // Red
  {0, 255, 0},    // Green
  {255, 165, 0},  // Orange
  {255, 0, 255}   // Magenta
};

Haddii useFixedColor lagu dejiyo true, saacaddu had iyo jeer waxay isticmaashaa hal midab. Haddii lagu dejiyo false, midabku si toos ah ayuu isu beddelaa ka dib markii waqtigu si buuxda u wareego.

Si dhakhso ah ugu helid qiimayaasha RGB ee saxda ah ee midab kasta, isticmaal qalabka RGB Color Picker: Color Picker .

Bandhigga waqtiga iyo wareejinta

Waqtiga hadda jira waxaa loo qaabeeyaa HH:MM waxaana lagu kaydiyaa buffer-ka xarfaha yar. Sababtoo ah bandhigu wuxuu uun yahay 8 pixels oo ballaadhan, qoraalku wuxuu si habsami leh uga wareegayaa midig ilaa bidix. Marka waqtigu si buuxda uga baxo bandhigga, midabka xiga (haddii la awoodo) ayaa loo xushaa wareegga xiga.

Muuujin

Ka dib marka la soo geliyo sketch-ka:

• SaaS-ga S3 wuxuu ku xidhmaa Wi-Fi
• Waqtiga waxaa laga midaynayaa internetka
• Waqtiga hadda jira wuxuu ku wareegayaa matrix-ka RGB
• Iftiinku si toos ah ayuu isu beddelaa maalinta iyo habeenkii
• Midabka qoraalku wuxuu ahaanayaa mid go'an ama wuu wareegayaa iyadoo ku xidhan dejintaada

Soo dejinta iyo linkiyada

Koodhka buuxa ee asalka ah ayaa hoos lagu bixiyay maqaalkan. Linkiyada qaybaha, qalabka, iyo xogta farsamada ayaa hoos ka heli kara maqaalkan.
