I have a Netduino+ hooked up on the Internet with data logging via Google docs.
Before i found this i was collecting the data via a SD card, on the Netduino.
I read almost every day Hackaday here i stumbled up at http://hackaday.com/2012/05/31/data-logging-directly-to-google-docs-google-drive/
But this didn't work for me, but i knew i was on the right trail.
After a lot of googleling it worked for me, this (story) is how i did it.
I have tried to simply the whole thing in only text, with links to more relevant documents.
Please ask in the comments and i will try to answer these.
If something relevant is asked i maybe will change this instructable to clarify some streps, so please read first then ask.
This way of collecting is also useful with writing software with a database, you don't need a server with SQL or other language.
Step 1: Filling a Spreadsheet
Filling a spreadsheet in google docs goes always via a form:
After hitting the Submit button on this form the URL is send to Google docs:
When you change the URL with the right values then you can send your data from a micro-controller or software to the spreadsheet.
