Here's the deal. AVR pins are not meant to source more than 40mA TOPS, and you are sourcing nearly 14x that much. I'd be very surprised if it still works.
So... I should use external power source to power anything greater than 40mA? Alright, thanks. 
Until you gain more knowledge and experience, be very careful measuring current. Measuring ohms (only with power off) and voltage (only with power on Wink ) are much less intrusive and dangerous, but current measurement can be very destructive if done incorrectly.
Will do, thanks.
