EBC Exercise 37 Logging to Sheets

Here are instructions on how to log data to a Google Sheet from JavaScript or Python.

Create a new Sheet
Create a new sheet by:
 * Going to https://sheets.google.com and clicking to Start a new spreadsheet, Blank
 * Give the sheet a meaningful name
 * Enter some column labels
 * Note the sheetID in the path

Get Credentials
Go to the class repo and change to the sheets directory bone$ cd exercises/iot/google/sheets

If you are using JavaScipt, go to https://developers.google.com/sheets/api/quickstart/nodejs and follow steps 1 and 2.

If you are using Python, got to https://developers.google.com/sheets/api/quickstart/python and follow steps 1 and 2.

Either way put the credentials.json file in the sheets directory.

JavaScript
bone$ ./demo.js 3.14 10
 * Edit demo.js and change the sheetID string to the string you noted above.
 * Then, run the example on your Bone. The arguments are the values to be logged on the sheet.

The first time you will have to paste a URL into your browser and paste a string back to the Bone.

Python
bone$ ./demo.py --noauth_local_webserver bone$ ./demo.py 3.14 10
 * Edit demo.py and change the sheetID string to the string you noted above.
 * Run the example on your Bone. The arguments are the values to be logged on the sheet.

The first time you will have to paste a URL into your browser and paste a string back to the Bone. You can leave off the --noauth_local_webserver after the first time.

Plot the Data
Go to your Google sheet and the new data, and a time stamp should be there.


 * Select the A column and select Format:Number:Date time
 * Select all the columns and click Insert chart
 * Select Line chart
 * Select Use row 1 as headers
 * Select Use column A as labels

Your data should be plotted. Try running your script again and the chart will update.
