Well I have done some tests and found that I can get over 250mA from an output pin of an Arduino. Of course this will / has damaged my Arduino but it is still actually working. I did this to to investigate what sort of currents are being drawn by connecting an LED direct without a resistor. This fo…

oh and this is the best quote imo

"Does my Arduino still work after this? Yes it does! Have I permanently damaged it? You bet I have!"

lol
