RTC, logging shield

Development Suggestions for the Arduino Project
1

Good Morning, evening, what ever :slight_smile:

Refering to this (nice and easy one):

qouting
I did post the following question:
Nice and easy project, thank you.
What I like to do, but do not have the knowledge to do, is to stack another shield,
"XD-204 Data Logger Shield | RTC | Data Logger for Arduino UNO" from ebay.
I did try to write my code myself, but ........
Anyone outthere can help out with that, will be most appreciated :slight_smile:
end qouting

The instructables is quite old, so I did not get any answer, I am sure this is an easy one
for most of you out there, so I hope some kind soule can help me out :slight_smile:

Thank You.

Here is a sketch I have so far, an Arduino UNO, RTC logging shield and a key pad LCD shield stacked.
And a BMP180 sensor.
This one works, but suggestions to add logging to this.
I did try meny things but non of them works, so a clue how to do it would be nice.

Thank You.
