I am planning to build a System that logs Data from an accelerometer on a SD Card and an Arduino UNO.
Atm I try to get the SD logger working shown below:
My sketch right now shall only create a file called “data.txt” and write a “10” into it.
What it actually does is to create the file, it gives out the “10” at the serial monitor at the FIRST run only but it does not write anything into the file. I have formatted the SD several times with different Programs and just don’t know out anymore. :~
