I am wanting to control eight micro servos. I have an idea on how I am going to power them wihth an arduino uno. I found a shield made by ADAFRUIT. NEW PRODUCT – Adafruit 16-Channel 12-bit PWM/Servo Shield – I2C interface « Adafruit Industries – Makers, hackers, artists, designers and engineers! Would this work for what I am looking for. Then put a 6 volt power source to the arduino jack and to the servos?
Would this work for what I am looking for.
Possibly. But, it isn't needed. An Arduino can CONTROL 8 servos without any shields. It can't POWER one, with or without a shield.
I feel this would make it easier if I for some reason, wanted to add more servos. Will I need different libraries for this or will it work with the servo library?
Does anybody have a circuit they can show me, that shows how to hook up 8 servos to an Arduino Uno and it having an external power source?
It's a matter of taking all the reds to the + side of the power supply, the blacks to the - of the power AND to the Arduino GND of course, and each yellow to a suitable different digital pin on the Arduino.
The pic attached (source: zoomkat) shows just one, but follow my words above and you'll be good. Budget 1A for each servo though...
I have hear things about needing a capacitor. Is that true?

What for ?
Where did you hear these rumours ?
Finally got round to doing a multi-servo pic, based on zk's iconic one... see attached.
Add no it does not work with the servo lib.
