Hi
Yes i am. I saw already many of your responses in the forum SurferTim.
I even tried to put pin4 low and pin10 HIGH in "void setup"
And with pin53 as pinMode(53, OUTPUT) with and without digitalWrite(53, HIGH); after.
I also tested the second code that puts them all in HIGH in the begining of "void setup".
/*
SD card test
This example shows how use the utility libraries on which the'
SD library is based in order to get info about your SD card.
Very useful for testing a card when you're not sure whether its working or not.
The circuit:
* SD card attached to SPI bus as follows:
** MOSI - pin 11 on Arduino Uno/Duemilanove/Diecimila
** MISO - pin 12 on Arduino Uno/Duemilanove/Diecimila
** CLK - pin 13 on Arduino Uno/Duemilanove/Diecimila
** CS - depends on your SD card shield or module.
Pin 4 used here for consistency with other Arduino examples
