Using Arduino and 8 servos!? What type of power source? Answered
Hey Arduino guys! I got a question.
I am using 8 servos with my Arduino. All the servos are hooked up parallel to the 5v and GND on the Arduino. All the control wires are hooked up on pins 2-9. I'm using 6 AA batteries as my pack. Is this OK for my Arduino? With all these servos moving at once, I want to make sure I'm not frying my board.
Oh, and, got another question.
The 6 AA batteries are too heavy for my robot spider, so I want to use two 9v batteries instead. But, this delivers 18v. Arduino and only go up to 12v. So, what can I use to bring my 18 volts from two 9v batteries down to 9v or 5v? What can I use? A voltage divider with resistors? A voltage regulator (whatever that is :P)?
