I´m using the Megaservo library. I use pin 9 and pin 10 for the servos.
The program just moves the servos from 0º to 180º. If I connect just one servo it works perfectly, but when I connect both of them the Arduino board seems to reboot every 2 seconds.
I´ve tried powering with the usb cable and with 2 9v battery in parallel, but nothing worked.
I suppose the problem is that is not enough current for 2 servos. I wanted to do a something like a line following robot, so I can not use a wall adapter.
What is the problem? How do you power 2 servos?
