This is flower shaped LED chaser using Arduino Nano and 132 LEDs.
Each LED bar contain 11 LEDs, connected together in parallel, and used 100 ohm resistors for LEDs protection.

Parts list:
1-Aluminum plate with 0.7mm thickness
2-Drill bit 5mm(for 5mm LEDs)
3-LEDs 5mm blue, white, red, green, yellow
4-Black color spray
5-100 ohm resistors
6-Connecting wire
7-Arduino Nano
8-Power supply 5v 500mA

You can change the flashing speed by changing the number that written after "delay" in the programming code.

Arduino Nano ile 132 LED'li Ultra Flasher Projesi​

Arkadaşlar, bu proje sadece bir "lamba yak söndür" işi değil; Arduino Nano'nun PWM çıkışlarını ve dijital pinlerini maksimum verimle kullanma sanatıdır. İster araç arkası çakar, ister atölye tabelası, isterseniz dekoratif bir aydınlatma olarak kullanın; 132 LED'in gücü her yerden fark edilecektir.

Teknik Kurulum ve Mantık:​

  • Kontrol Ünitesi: Arduino Nano (ATmega328P), küçük boyutuyla projenin beynidir.
  • Sürme Yöntemi: Arduino'nun pinleri 132 LED'in toplam akımını taşıyamaz. Bu yüzden LED'ler genellikle Transistör (BD139/140) veya MOSFET (IRFZ44N) üzerinden sürülür.
  • Grup Kontrolü: 132 LED genellikle paralel/seri gruplar halinde (örneğin 11'li 12 grup veya 22'li 6 grup) bağlanarak yönetilir.
  • Efektler: Kod içerisindeki delay() veya millis() fonksiyonları ile polis çakarı, yavaş dolan ışık (knight rider) veya ritmik flaşör efektleri verilebilir.

Usta Notu:​

Bu projede en kritik konu besleme ve ısınmadır. 132 LED, rengine göre (örneğin beyaz veya mavi ise 20mA'den) toplamda 2.6 Amper civarı akım çekebilir. Bu akımı sakın Arduino üzerinden geçirmeye kalkmayın, Nano'yu anında yakarsınız! LED'lerin artı (+) hattını doğrudan 12V veya 5V beslemeye bağlayın, Arduino sadece transistörlerin 'Gate/Base' ucunu tetiklesin. Ayrıca direnç hesaplamasını her grup için ayrı yapın ki LED'lerin ömrü uzun olsun.

132 LED Flasher: Kısa ve Akıllı Kod (V2)​

Bu kod, for döngüsü kullanarak aynı işi sadece birkaç satırda yapar. En büyük avantajı, en baştaki hiz değerini değiştirerek tüm animasyonu hızlandırıp yavaşlatabilmektir.
Kod: 
/* uydudoktoru.com - 132 LED Ultra Flasher (Kısa Versiyon)
  Pinler: 2'den 13'e kadar (12 Grup)
*/

int hiz = 100; // Tüm animasyonun hızı (ms cinsinden). Değiştirerek dene!

void setup() {
  // 2'den 13'e kadar olan tüm pinleri çıkış yapıyoruz
  for (int i = 2; i <= 13; i++) {
    pinMode(i, OUTPUT);
  }
}

void loop() {
  // 1. ANİMASYON: Sırayla Yak ve Söndür (Knight Rider)
  for (int i = 2; i <= 13; i++) {
    digitalWrite(i, HIGH);
    delay(hiz);
    digitalWrite(i, LOW);
  }

  // 2. ANİMASYON: Tersten Sırayla Yak ve Söndür
  for (int i = 13; i >= 2; i--) {
    digitalWrite(i, HIGH);
    delay(hiz);
    digitalWrite(i, LOW);
  }

  // 3. ANİMASYON: Hepsini Yak, Hepsini Söndür (Flaşör Etkisi)
  for (int i = 2; i <= 13; i++) { digitalWrite(i, HIGH); }
  delay(hiz * 2);
  for (int i = 2; i <= 13; i++) { digitalWrite(i, LOW); }
  delay(hiz * 2);
}

Usta Notu:​

bu kısa kodun güzelliği şurada: Eğer animasyonun çok yavaş olduğunu düşünürsen sadece int hiz = 100; kısmını 50 yaparsın, tüm devre mermi gibi hızlanır. Eski kodda bin tane delay satırını tek tek değiştirmen gerekirdi. Ayrıca bu yapı sayesinde Arduino'nun hafızasında çok daha az yer kaplar, işlemciyi yormaz.
