I need some help with a project where I am making a humanoid robot. So I have planned to use 12 S9G0 micro servo motors connected to a servo driver and to the Arduino UNO board.
The problem is that I was originally going to use a 5V battery, but I did some research and some people have said about using a 12V battery? I am unclear because how much volts would each the servo motors have then if my battery was 12V?
I am new to Arduino, so apologies.
BTW, here's the servo driver that I am going to be using Overview | Adafruit PCA9685 16-Channel Servo Driver | Adafruit Learning System
