Pillowcase Alarm – Connor Gallaher

For my warm-up project, I chose to create an alarm embedded into a pillowcase.  I wanted to combine input via a light sensor to activate the alarm, driving output through the LEDs and the buzzer.  In doing so, the purpose is to wake the user up gently.  When the light sensor detects light at a certain level, the alarm goes off.  This is to emulate light coming into a room in the morning, which would then prompt the alarm to go off and wake the user.

If I had more time, I would have implemented a switch to allow the user to turn the alarm off.  As a student pointed out in class, the user could simply turn off the switch on the board, but reaching underneath the pillowcase (I sewed the main board on the inside of the pillowcase) to reach this switch is not very practical.  A switch on the outside of the case near the light sensor, for example, would have solved this issue.  Additionally, for testing purposes, I set the outputs to be activated at a high level of light (as can be seen in the video I shine a lamp directly on to it – a very high level of light).  But, I would have liked to play around with the numbers more in order to simulate a more accurate environment in which this would be used.
