Responding to Repl #10
It seems to me if you have a resistor in series with the capacitor it will "resist" the flow of current to your servos - the very opposite of what you want - but I confess this is not something I am confident about.
The idea of the resistor between the servo signal and GND is to deal with the short period while the Arduino is going through its reset process and has not yet got to the code
myServo.write(pos)
Up to that point the signal line may be floating and some servos behave strangely in that situation. I found the resistor was helpful in preventing unwanted excursions during the startup period. If the servo is not trying to move it may draw less current.
