I have Arduino zero and I'm using two continous parallax servos for movement. I have 2x5AA batteries, 5 for arduino and 5 for servos (1.5V each battery).
In code I only use servo.attach(pin) nothing else and the moment I plug the servo to arduino pin it starts moving when I plug 2 servos noone of them move. Changing speed in code doesn't effect servos they always move full speed in one rotation.
I cannot figure out what is wrong since this same setup worked but I've changed batteries for servos today to new ones and everything seems to be going wrong.
Here is how it looks like Imgur: The magic of the Internet (there isn't a wifi shield on the top anymore). So one battery pack is underneath the whole robot and one battery pack is underneath the arduino.
