maximum amperage for arduino uno


hello,
i've got arduino uno , want connect 2m led strip. since voltage stays equal individual led, amperage has increase, correct?
now i'm afraid break arduino applying amperage - possible or have safety mechanism?
if can break it, whats maximum amperage , how 1 led need?

thanks in advance,
flap

a 5v strip?  depends on how powering uno , if using jack or vin voltage.

usb limited 0.5a total normally, , if power jack 12v say, you're generating (12 - 5) x i
watts of heat if pulling current of 5v, @ point on-board regulator shutdown
due overheating.
