# ST B-L072Z-LRWAN1 - Button to AWS Example
|
||
|
||
This is an example code for building an AWS IoT application that sends you text messages using Twilio.
|
||
|
||
You'll need:
|
||
* ST-B-L072Z-LRWAN1
|
||
* An AWS account
|
||
* A Twilio account
|
||
|
||
You need to load this sketch onto the ST-B-L072Z-LRWAN1. The sketch will send a heartbeat every 15 seconds and will asyncronously send an alert whenever the button is pressed.
|
||
|
||
Once you confirm that the device is connecting and sending data via Helium Console, you'll want to setup an integration to AWS IoT.
|
||
|
||
Once you do that, you want to create a Lambda function using the Python file here: lambda_button_text.py
|
||
|
||
You'll need to set environmental variables to make it work:
|
||
* TWILIO_AUTH_TOKEN: get this from your Twilio dashboard
|
||
* TWILIO_ACCOUNT_SID: get this from your Twilio dashboard
|
||
* TWILIO_ASSIGNED_NUMBER: get this from your Twilio dashboard
|
||
* USER_NUMBER: this is the cell phone number which will get text message alerts when the button is pressed
|
||
|
||
Once you save the lambda function, you will simply need to connect the lambda function to an AWS IoT trigger. Use the rule query statement: SELECT * FROM "helium"
|
||
|
||
Now you're done! Press the button and you should get a text message.
