That draws too much current only a regular standard 5mm led can be powered by ezb , get you one of those relay kits for arduino and it will use signal from ezb to trigger on.

#2  

but it states it runs on less than 5v......

#3  

Volts is not the problem , 25 ma (thats .025 amps) is what ezb is rated for from a single output which is the average led. A laser probably draws between 100 ma - 300 ma maybe more. Just check the current draw on your laser diode and make sure its not more than the servo output current rating. It's in ezb manual.

Use a switching transistor. $3 at Radio Shack. TIP120 Darlington Transistor.

how do i use it? the transistor i mean....i would love to add a laser pinter....

this transistor like the infamous hall monitor.....i dont know how to use them,

@hoolagen1, Go to the URL that Choyster lists. That will tell you how to use the transistor. Also DJ had a really slick jpg of the TIP 120 showing a wireing diagram but I tried going back to get it for you but it had been moved. May be DJ will put it up agian.

Here's the diagram Bookmaker is talking about.
