Hey Guys,
I followed a guide on youtube to get my multiple servos to be controlled one by one for my robot arm. But every time i control one, all the other one starts jerking around like crazy.
- I am using bluetooth to control via android
- I have separate power supply for servo/uno
- I used toroids on pretty much all the wires
- Tried with 6v/5v ubec and also tried straight 12v with no regulator for servos
I am only getting the issue when i am using a slider to move them, if i use a button that presents its destination like say 100 degrees, its fine. nothing jitters, only that one servo moves like it should.
I am assuming the problem is in the code itself. But what gets me is how does it work fine for the guy on youtube but not me. I even DL his exact code and APK for android, still happening.
Any kind of suggestions would be wonderful. thanks!
