Weird servo twitching

EagleEyeEric:
Oh gotcha. Sorry. But having more amps than necessarily isnt a bad thing? It wont damage or do anything weird?

You can have a problem if you have too few amps - but never with too many (except a problem for your wallet, perhaps).

Here is a diagram of my wiring. The only difference is I have 4 AA batteries instead of the one shown on the diagram

You have the button powered from the 6V servo supply, thus frying(*) the Arduino. The button must
be from the Arduino 5V logic supply, its a logic signal.

(*) unless you were particularly lucky.

How do I use the power supply transformer? It doesnt look like it comes with a plug to plug into the wall. What kind of plug do I need to correctly plug it into the wall?

Also could I use this(5V 10A switching power supply : ID 658 : $29.95 : Adafruit Industries, Unique & fun DIY electronics and kits) to plug into my Arduino and it will supply the power to the servos? or does it not work like that?

Connect the wires associated with whatever AC wall plug you want to the "L" (line, hot) and "N" (neutral, ground) terminals on your power supply.

In the US, white wires are often "N" and black are often "L". In Europe the wires are often blue and brown.

Hmmm. It is also just possible to cut off the end of the wires on this power supply and get the power and ground wires from there? It has the same 5V and 10 A as the transformer from ebay.
