I know everyone has done it at least once: that moment where you hit your alarm and think to yourself “just five more minutes of relaxing and then I'll get out of bed” only to realize you’ve slept for an hour or so and completely missed your mark.
This is a problem that plagues many people, and one we were looking to combat with our new alarm clock. An issue with alarms in general is they only take one button to stop, something so easy most can just hit and go back to sleep without much thought; we wanted to create an alarm clock that requires movement and voice to stop, something that makes you get up and move in order to solve. Our method has 3 parts that help make it work. Our first part is a button that will activate the alarms/sensors, which someone can use to wake up a sleeping friend. Our second sensor is a motion sensor, which will activate once it detects the person getting out of bed. Our third sensor is a microphone, located away from the bed, that a person will have to walk over and yell into in order to send the final signal back to the main board to stop the alarm.
This solution makes sure the person has to actually get out of bed, move, and speak to stop the alarm, helping them wake up more and ensure they won’t just get back to snoozing. Using our IOT skills we are able to switch states to activate and deactivate alarms and lights when our sensors pick anything up, document movement throughout the night to see how the person sleeps using thingspeak, and most importantly, have boards communicate with each other to ensure that our setup can be used anywhere in different rooms. The only current difficulty is getting the alarms to work, so currently we will be using LEDs as placeholders to show when the alarm has been activated and deactivated by the microphone and ultrasonic sensor.

ThingSpeak Live Data
The sensor we chose to hook up to live data was our ultrasonic sensor, this way we can track if the individual is having a restless night, moving around a lot, or is frequently getting up through the night.
