I tried to control servo motor by using servo library in Arduino and it is working fine. But when I use separate power supply and function generator, it is not working. It is go to end which means 180 degree.
I used SG90 servo motor. Separate power supply voltage is 5V like arduino. I used PWM 50Hz in Function generator and duty cycle 3%. If I set 1% duty cycle, it is also going to end. PWM peak voltage is 5V.
