I bought 2 "RC Hobby Sub Micro Servos 9g Torque Servo" on ebay.
I'm not familiar with them, and I tried to test them with the knob demo. I downloaded the library, uploaded the program, twisted the pot to one side and then to the other. Nothing happened. I uploaded the sweep program, nothing happened. The servo's voltage range is from 4.8v to 6.0v.
If anyone knows about these servos or some solution, please let me know. THX.
