Circadian Rhythm Light Watch

The proposed biological clock is a mechanism that is designed to help adapt to environments embedded in our genes cycling from sleepiness to alertness close to a 24-hour period. Majority of the clocks used daily display time in units of days, hours, and seconds, omitting the periodic cycle of our biological clock. Performing routines with respect to the circadian rhythm has shown to be beneficial to the metabolism, and overall health. The lighting system shall keep time and provide circadian rhythm lighting output. An Arduino programmed watch using a periodic function given circadian rhythm parameters is displayed through a neopixel L.E.D. lighting system displaying it as a function of time over a 24-hour period. Red, blue, and purple colors are used to represent the different levels of alertness throughout the day to measure and verify the body's circadian rhythm. The effectiveness of the system against system requirements is presented and future modifications are suggested.
