Custom IoT Alarm System
One of several projects I have been working on lately is a door alarm system with text message alerts using an Arduino, 1x sensor, a little code, and Twilio's Programmable SMS API.
I've even gone as far as adding a smoke alarm for text message smoke alerts.. in case my home is burning down while I am not home.
Which I am designing a custom interface to display relevant information and feed back from these alarms and sensors that I keep on display via a small monitor on my desk. The icons turn colors as the corresponding sensors are triggered.
