RC servo bozulurmu?

[gambit1244]

merhaba ustalarım bir rc servo için kod yazdım aşağıdaki kod isiste düzgün olarak çalışıyor fakat kite attıgımda servo en sona kadar gitip cazur cuzur otüyor sadece
geri gelmesi gerekirken geri gelmiyor neden boyle yapar servo motoru bozmuş olabilirmiyim
(servo motor hareket ediyor fakat saçmalıyor)
