# Smart Mat Alarm Clock 

Alarm clock on smartphone that is turned off only by standing on a pressure sensitive mat for 10 minutes




## Summary

 - This project had 3 different pieces

   - The smart mat  

     - Pressure sensitive mat that acts as button of sorts - when stepped on, its resistance drops to nearly zero and allows current to flow through.

     - Raspberry Pi Zero W that runs a python script which sends HTTP requests to the API hosted on my server

       - Sends periodic "heartbeat" POST request every 30 seconds

       - Sends POST request whenever the state of that mat changes

       - Has ghosting/accidental step off prevention - mat's state must change for >5 seconds before POST request gets send to API 

   - The alarm clock software and automation on my phone  

     - "Wake me up!" Android app provides the alarms that are monitored and triggered by "Tasker"  

     - "Tasker" Android app monitors and triggers alarms provided "Wake me up!"   

     - The Tasker app is where all of the logic lives:

         - Request current state of the mat (stood on / not stood on) every minute

         - If mat is not being stood on, retrigger the alarm and reset the minutes stood on counter  

         - If 10 consecutive iterations (each 1 minute long) occur where the mat is stood on, then disable the alarm

   - The public API hosted on my server 

     - Node.Js with Express 

     - Receives the mat's current state and filters out false positives
