Thanks a lot Korman
! ..also for the 'direct battery supply' advice
In order to make it 12 servos, I am planning to use 10 PWMs for 10 Servos, but 2 specific PWM signals to drive the remaining 4 servos, because (out of 14) there are 2 servos that will always have the same orientation as another 2 servos. i.e. I will be connecting one
PWM signal wire from a pin, with the yellow (signal) wires of two
different servos (twice).Please correct me if I am wrong
Yes, you are totally wrong and you really should stop using acronyms you don't understand. To repeat for the uninitiated:
On the Arduino you control hobby servos only
with the Servo library and you never, never use the hardware PWM on them. It simply wont work otherwise.
So please, forget about PWM or PPM when speaking about those hobby servos of yours. It'll create only confusion in your mind.
Also, drive all
your servos with the Servo library, you don't have the knowledge to drive servos with your own code directly. If you need more than 12 servos, get an Arduino Mega.
As to the example, use Google and look for Arduino and Hexapod robot. They use lots of servos, usually 2 per leg for a total of 12.
