Using AWS IoT Button and Nexmo to Make a Phone Call

The author, a father, wanted to allow his 8-year-old son to make a phone call to the teacher stationed in the cafeteria before school starts, but was hesitant due to the cost and potential for him to lose it. He discovered an AWS IoT Button, which is a cheap device that can be linked to Amazon Web Services, and used it to send an email when clicked. To connect this with making a phone call, he integrated the Nexmo Voice API, which enabled him to make automated calls. The author created a Lambda function using the AWS IoT Button blueprint, and then connected it with the Nexmo code to create a fully functional system that allows his son to make a phone call by clicking a button on the IoT device. This innovation has saved him time in his morning routine and given his son more independence.
