Here are instructions on how to log data to a Google Sheet from JavaScript.
Contents
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 step 1.
If you are using Python, got to https://developers.google.com/sheets/api/quickstart/python and follow step 1.
Either way put the credentials.json file in the sheets directory.
Run the example
JavaScript
- Edit demo.js and change the sheetID string to the string you noted above.
- Load the API
bone$ npm install googleapis
- Then, run the example on your Bone. The arguments are the values to be logged on the sheet.
bone$ ./demo.js 3.14 10
Python
- Edit demo.py and change the sheetID string to the string you noted above.
- Load the API
bone$ pip3 install --upgrade google-api-python-client oauth2client
- Run
Then, run the example on your Bone. The arguments are the values to be logged on the sheet.
bone$ ./demo.py 3.14 10
Go to your Google sheet and the new data, and a time stamp should be there.
Plot the Data
- 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.
