I configured an AWS dashbutton that calls a Lyft ride to the address of my next google calendar event. I wrote a script that calls five APIs, maintaining the constraint of no written user input or output. To store my credentials for those APIs, I am using a DynamoDB and an AWS lambda function to configure the button.
How it works?
- The button lives next to my door.
- I push the button.
- The physical push connects the button to my wifi and wakes up the serverless AWS lambda function.
- The lambda function just calls the python script.
- The script will go to my google calendar and check my next event and grab that address.
- The next function will grab that address and convert it to a tuple of longitude and latitude.
- The next API call will request a Lyft ride from my home to that point.
- The next API call will send me a Twilio notification with the result of the process.
- The lambda function in the AWS server will go back to sleep.
The script can also:
- Import and save my different credentials in a DynamoDB.
- Request new tokens when a credential has expired.
- Thanks to the AWS server, save some usage statistics.
- Python. All the calls to the different Apis are written in Python.
- AWS lambda for responding to the Dashbutton push.
- Twilio for alerting the user when an error happens.
I’m using a number of APIs to work properly:
- Google Credential
- Google Calendar API
- Google Maps Requests
- Dynamodb (I’m using boto3 to work with the dynamoDB)
- Lyft API (I’m using the lyft_rides library to work with the Lyft API)
- Twilio API (I’m using the twilio.rest library to work with this API)
All the dependencies are listed in requirements.txt.
This project was completed in under a month, so there are definitely areas for improvement. Specifically:
- Tests are needed.
- Functionality for setting up the button from different “homes”.
- Functionality for setting up different buttons.
Hi! My name is Cristina Rodriguez , and I am a software engineer. I received training from Hackbright Academy, an engineering bootcamp for women in San Francisco (graduation: March 2017). I used to work as a project manager for a software company, and there I got interested in learning Python and being able to create my software projects. I’m currently seeking a front-end developer role in the San Francisco Bay Area. If you have a role that I should hear about, feel free to email yosola at gmail.
