Story

Our project began with very little knowledge and understanding of how to write code to run in a particle Argon. However, our team wanted to create something practical for everyday use, but maintain a simple design. We discussed several different possibilities, but most of our ideas were too complicated for us to create as beginners. So, we decided to create an emergency alarm communication system that will allow the user to call for help simply by speaking into a virtual assistant program.

An Amazon Echo Dot was used to recognize a trigger word, “Alexa trigger call help”. The Echo Dot would then send an output response to the IFTTT program set up so the Particle code could send a signal through an Argon. At the same time, a notification is sent to a phone number saying that the user is in an emergency and requires immediate help. A second Particle Argon receives the transmitted signal from the first Argon and lights up a red LED indicating there is an emergency.

To reset Alexa and stop the LED, say “Alexa trigger cancel help” and both Particle Argons will reset. We hope this project helped and inspired others to pursue IOT projects!

        digitalWrite(D7, HIGH);

        digitalWrite(D7, LOW);
