Connecting to a phone app via a Bluetooth connection enables this remote control operation for the system. This way users can set an alarm from the comfort of their bed. In addition to functioning as a standalone device, one additional requirement is that the alarm clock should have an option for remote control of the system. An LCD screen displays the time and displays the menus for the alarm, and a three-button interface with a rotary encoder provides all the user input and feedback needed to run the alarm clock as a standalone device. A physical user interface with buttons and a screen was also required. It is very annoying and is sure to wake even the heaviest of sleepers. A simple piezo buzzer fits this requirement perfectly. The system also needed a backup audio alarm in case the sunrise wasn’t enough to wake you.

This mode would allow the user to utilize the system as a “night light” if they wake up in the middle of the night, or simply to enable using the full spectrum LED as a traditional light source in the room.Ī functioning sunrise alarm clock can lead to more restful sleep and a more gentle wake-up experience through the simulation of a natural sunrise by utilizing a full spectrum LED. It also required an alternate mode where the user could utilize the light as a normal light source outside of the sunrise alarm function of the clock. The LED also required analog dimming, which prevents the annoying flicker that is characteristic of most PWM methods. This was intended to not only create a pleasing light but also help combat Seasonal Affective Disorder on those dark winter mornings. It required a full spectrum LED to mimic sunlight. This sunrise alarm clock ( Figure 1) adheres to several design requirements. For the busy professional person or student, the sunrise alarm clock can mean waking up peacefully for a job or class.

Rather than jarring you awake with an annoying alarm, a sunrise alarm clock slowly turns on a light in your room over a configurable schedule to simulate a natural sunrise that allows your body to naturally wake up.

The clock uses a full spectrum LED to wake you up using your body’s natural response to sunlight. This article discusses the design and construction of a programmable light-based alarm clock.
