With this project, I aim to be fully able to see the data collected by an arduino in my house and to be able to insert new data with some specific measurements I have to do myself. The specifications for this app come in at least 3 levels. For the Mobile Computing with App Inventor – CS Principles Mooc, I started the project with level 1 specifications.
This post is part of the serie App Inventor Project : android app to interact with a google spreadsheet. The tutorials will go over these parts. In the first one, I described the context. In this one, I describe the specifications. In the following ones I will explain how I coded with App Inventor 2 so as to meet the specifications.
Level 1 specifications
Click on the screen shots to enlarge them.
 |
App Start Screen – shows the user interface at the top and the data already stored in our database (the google spreadsheet). |
 |
Check « line chart » View and the display changes from table to line chart. There may be a delay before the new display. |
 |
See every details with the google charts API. It works with a tablet or a phone : touch the display and it shows the data at this point. |
 |
The date picker is user friendly. |
 |
The app inventor 2 time picker |
 |
Notice time and date display at the left of the date picker. The keyboard appears when user wants to fill the level she measured |
 |
Response 200 : it worked ! |
 |
Make sure the data is here ! |
Level 2 and above specifications
The app will be able to display the temperature data, and the boilure on duration on my devices. The display will use the same functions the level 1 uses. The only difference is that the user will be able to specify some options and they will be sent to the html/javascript template and included in the JSON data used to generate the displays.
So now let’s design the app and code it !
