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

Blank Google Sheet

  • Note the sheetID in the path

SheetID

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.

Run the example

Python

  • 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.
bone$ ./demo.py 3.14 10

The first time you will have to paste a URL into your browser. When you see

Appnotverified.png

go to Advance and click the Go to Logging Data (unsafe). It's unsafe since Google hasn't verified our app.

Finally paste the string back to the Bone.

JavaScript

  • 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.
bone$ ./demo.js 3.14 10

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

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

Formatting the Date

  • Select all the columns and click Insert chart

Insert chart

  • Select Line chart
  • Select Use row 1 as headers
  • Select Use column A as labels

Chart formatting options

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