This is an AWS Lambda function to be used in association with an AWS IoT button. It configures the IoT button to send customized email and text messages using the Amazon Simple Notification Service (SNS).

1. Download the iot_button_notifications.js file

2. Copy and paste the entire code in your Lambda function on the AWS console, and make the following three changes- a. Find const TOPIC_ARN in the code and replace the existing ARN text string with your SNS topic ARN

   b. Find var localTimeZone in the code and enter the UTC time offset of your local time zone.

   c. Find var emailSubject in the code and edit the message if you prefer a different subject for your notification emails.

This code can also be modified and used for other use-cases involving the AWS IoT button.
