> 4. Would servo controller like this be effective in doing what I need to do? http://www.pololu.com/catalog/product/1356No because it uses a USB input and the Arduino can control servos by itself without a "controller".
•Three control methods: USB, TTL (5V) serial, and internal scripting.
And considering the amount of power needed, what kind of power adapter would you recommend? I have been googling for suitable power adapter but there doesnt seem one spec at 18A or higher
Is there anyway to go about knowing how much current I would actually need for 18 of them?
