Processing ile Rgb Led Kontrolü

Rgb led ismini baş harflerinden (red, greer, blue) gelen ana renklerden alır.Bu renkler karıştırılarak diğer ara renkler oluşur.Çalışma mantığı bu şekildedir.4 tane bacak bulunur.Bu bacaklardan 3 tanesi kırmızı, yeşil ve mavi renk bacakları diğer bacak ise ortak anot ise artı ortak katot ise eksi bacaktır.Bu projemizde processing ile rgb led kontrolü programdan kontrol edip istediğimiz rengi almamızı sağlayacağız.

Malzemeler:

1. Arduino
2. Rgb led
3. Direnç (100×2 ,180×1)
