   Programma kodini arduinoga yuklash uchun quyidagi rasmdagi
   

instrumentga sichqoncha ko’rsatkichini olib borib bosing.

Tizim kompilyatori dasturni tekshirib xatosiz bo’lsa kontrollerga yuklaydi va programma ishga
tushadi. LED dioddan tuzilgan svetaforni berilgan vaqt oralig’ida o’chib yonishni boshlaydi.
Agar dastur kodida xatolik bo’lsa kompilyator bu xatolikni qizil rang bilan yoritib ko’rsatadi. Xatolikni tuzatib dasturni qayta yuklanadi.

   Topshiriqlar:
   

1. 
   LEDni yonib o’chish vaqtlarini sketch (dasturda) o’zgartirib ko’rib svetaforni yashil va qizil ranglgrini yonib turish vaqtlarini i kuzating.
   
2. 
   Kontrollerdagi chiqish kontaktigini (pinini) dasturda va mos xolda kontrollerda ulanishini o’zgartirib ishni bajarib ko’ring.
