Merhaba, arduino devre elemanlarını tanımaya ve onların bağlantı şekillerini öğrenmeye devam ediyoruz. Bugün Arduino – 9g Micro Servo Devresi kuracağız.
Görselde gösterildiği gibi bir devre kuracak olursanız devrenin tamamlanmış olduğunu göreceksiniz.
Test Kodu
// Include Libraries
#include "Arduino.h"

#define SERVO9G_PIN_SIG 2
// Global variables and defines
