School Project Help

I should have been more precise with my last question:
In what intervalls can the data been uploaded to the PC? Will that be done by

  • USB
  • Ethernet
  • Xbee
  • SD card
  • other
    ?

You have around 2,500 bytes available on a 328 and you want to store 10x10 bits = around 12 byte/100ms = 120 byte/s => 20 seconds..

So you should consider an SD card shield....
