In image above we have MOSI MISO SCK Pins mentioned in lower side of Arduino image in a pack of six pins together
Are they all can be applied for SD Card module to get it work as a WAV Player ??
those are the same pins as on 11, 12 and 13
The ICSP header (the 6 pins) has the exact same signals as pins 11, 12 & 13 - they are connected.
That means it's all the way safe to connect a Card module there ????
Are all the in parallel with 11 12 & 13 ???
yes. it is the SPI header used for shields even for boards which have SPI on other pin numbers or even don't have SPI on the side headers at all
Yes. You will also need to connect CS to another Arduino pin.
So Suppose I apply this MOSI MISO SCk pins here in case . .
Then is it possible to use 11 12 and 13 for other purpose like input / output ?????
No. They are connected to the same pins of the processor.
I see . . Well !!
