How to use Google docs for data logging

Step 2: Use Google docs to collect data of a micro controller.

To use Google docs you need an account, if you make your project for somebody else then make for that project a new account.
Login and go in  google docs to new-->form
Very importantvVia this form the data is collected and put in the spreadsheet.
No form, No spreadsheet.

For every parameter you will follow, make a field.
(# means a number
 : means "this will be" "in the URL")

Standard HTML:
Text field : entry.#.single
textarea    : entry.#.single
radio     : entry.#.group  // Same group number belongs to the same group.
checkbox   : entry.#.group  // Same group number belongs to the same group. entry.3.group=value1&entry.3.group=value2
option/select : entry.#.single

Special:
scale     : based on type radio on a row
grid     : based on type radio in a grid

The most used fields would be a text field for values and radio button for boolean.
