Hi i need to do some project with arduino right now but i need to arduino make an power output of 12V and 0.3A, and my question, arduino is capable of doing that??? because i need to power more than 300 electrodes with it, its possible to do it with transformers conected to arduino board?? thanks in advanced

No. Not without help. You need a 12V power supply and a transistor. You can not do it with transformers.

Here is a driver circuit.

You will need a 12V power supply (not just a "transformer").   Transformers are AC.

What?   Do you need 300 individually-controllable 12V/300mA outputs?

@DVDdoug, your link don't work, try:
Driver Link

You should use external power supply, 12V 3A but do not directly to arduino.

The Arduino has no 12V output.  Only a 5V output.  So, you could use a 12V power supply and connect it both to the Arduino via the power jack, AND to whatever you've got going on with those 300 "electrodes". 

Resurrecting something?
