Alarm Pillow

Description:
For this assignment I wanted to tackle the biggest painpoint in my life: waking up in the morning. I decided to use a daily object: the pillow, to wake a person up. Every night when the person sleeps on the pillow, the pillow will check if the person is awake after 8 hours. After 8 hours it will start ringing to wake the person up. I tried to hook up a photocell to the circuit, so that if it is 8 hours later and it is daylight time, the pillow plays a harsher tune. But I was unable to wire the photoresistor to the pillow, due to lack of long cables. I think that would be a great addition.
Code:
