שיעור 9 - לדים ומנגינות

ברוכים הבאים לשיעור התשיעי!

השיעור מורכב מסדרה של סרטונים, צפו בהם לפי הסדר.

תהנו 🙂

חלק 1: מתחילים!

חלק 2: מסך לדים

חלק 3: ספריית FastLED

  #include <FastLED.h>
  #define NUM_LEDS 16
  #define DATA_PIN 33   
  CRGB leds[NUM_LEDS];

void setup() {
  // put your setup code here, to run once:
  FastLED.addLeds<NEOPIXEL, DATA_PIN>(leds, NUM_LEDS);
}

void loop() {
  // put your main code here, to run repeatedly:
  leds[0] = CRGB::Red; 
  FastLED.show(); 
  delay(30); 
}

חלק 4: מדליקים עוד לדים!

  #include <FastLED.h>
  #define NUM_LEDS 16
  #define DATA_PIN 33   
  CRGB leds[NUM_LEDS];

void setup() {
  // put your setup code here, to run once:
  FastLED.addLeds<NEOPIXEL, DATA_PIN>(leds, NUM_LEDS);
}

void loop() {
  // put your main code here, to run repeatedly:
  leds[0] = CRGB::Blue; 
  leds[4] = CRGB::Red; 
  leds[9] = CRGB::Pink; 
  FastLED.setBrightness(50);
  FastLED.show(); 
  delay(30); 
}

חלק 5: לדים רצים

void setup() {
  // put your setup code here, to run once:
  FastLED.addLeds<NEOPIXEL, DATA_PIN>(leds, NUM_LEDS);
  FastLED.setBrightness(50);

}

void loop() {
  // put your main code here, to run repeatedly:
  // Turn the first led red for 1 second
  leds[0] = CRGB::Red; 
  FastLED.show();
  delay(1000);
  
  // Set the first led back to black for 1 second
  leds[0] = CRGB::Black;
  FastLED.show();
  delay(1000);
}

חלק 6: סיפריית מנגינות

#include <melody_player.h>
#include <melody_factory.h>

int buzzerPin = 14;

MelodyPlayer player(buzzerPin);

void setup() {
  String notes[] = { "C4", "G3", "G3", "A3", "G3", "SILENCE", "B3", "C4" };
  Melody melody = MelodyFactory.load("Nice Melody", 175, notes, 8);
  player.play(melody);
}

void loop() {}

חלק 7: פתרון המשימה

  //Melody library
  #include <melody_player.h>
  #include <melody_factory.h>
  int buzzerPin = 14;
  MelodyPlayer player(buzzerPin);
   
  //FastLED Library
  #include <FastLED.h>
  #define NUM_LEDS 16
  #define DATA_PIN 33   
  CRGB leds[NUM_LEDS];

void setup() {
  String notes[] = { "C4", "G3", "G3", "A3", "G3", "SILENCE", "B3", "C4" };
  Melody melody = MelodyFactory.load("Nice Melody", 175, notes, 8);
  player.play(melody);
  
  FastLED.addLeds<NEOPIXEL, DATA_PIN>(leds, NUM_LEDS);
  FastLED.setBrightness(50);
}

void loop() 
{
    for(int dot = 0; dot < NUM_LEDS; dot++) 
    { 
        leds[dot] = CRGB::Red;
        FastLED.show();
        // clear this led for the next time around the loop
        leds[dot] = CRGB::Black;
        delay(30);
    }
}
