How to power-up SD Card manually with digital pins to control its power consump.

Using Arduino Storage

Thanks PaulS for the idea. I see, 40mA of current is not enough to power up the card. This is what I did then; I set the pinModes of D2,3,4,5,6 to output and turn them to HIGH. I connected all these pins to +v of the card. (Crazy stuff) And it worked!

I am very carefull with my code because all D2,3,4,5,6 pins are directly connected to each other.

Thanks again paul!
