Best method for powering 6x servo motor Arduino robotic arm

Hi Sam
Where do you expect these spikes. The output of the power supply should be clean and should not require any conditioning. You certainly don’t want capacitors across servo control signals as if you distort them too much the servos will quit.
Not a good idea to just throw capacitors around willy nilly anyway because given the right conditions you can get some very interesting and usually unwanted results.
