Summary of Wake-U-Up System
This Sleep and Wake-up Assistant project enhances traditional alarms by combining adjustable LED lighting, motion detection via an accelerometer, vibration motors, and custom voice recordings. The system simulates sunrise to gently wake users during light sleep phases, features an active snooze mode that checks for movement, and allows personalized alarm messages to ensure timely awakening.
Parts used in the Sleep and Wake-up Assistant:
- LED light
- Accelerometer
- Vibrate motor
- Snooze mode logic
- Voice recording module
This project is aimed to design a ‘Sleep and Wake-up Assistant’. Different from a normal alarm clocks which can only make noise, this alarm clock is designed to wake up a person in a comfortable and effective way by involving sound, light stimulation, motion detection and vibration. The functions of this alarm system are:
( i ). This system has an LED light. Before the user sleep in the night, the LED can be used as a reading light. The lightness is adjustable and can be timed to gradually dimmed as the user falling asleep. In the morning, the lightness will be gradually increased before the set wake up time (e.g. 30mins ahead) to simulate the sunrise.
( ii ). An accelerometer will be put on the bed or under the pillow to monitor the moving pattern of the user before wake him/her up. There will be a window before the user’s set alarm time, once the system considers that the user is in a light sleep phase, it will wake the user up even before the set time.
( iii ). To help the user wake up effectively, a vibrate motor will be placed under the pillow. It will start working when the alarm start.
( iv ). This alarm clock has a more active ‘Snooze’ mode comparing to a normal alarm clock can just timing. After the setting alarm time has passed, the accelerometer will keep detecting if the user is still on bed by tracking is there any movement.
( v ). Sometimes, people may wake up late and found out the missed a very important event. If someone told them while waking them up, it would be much likely that they can get up in time. This system allows the user recording a few sentences and use it as alarm sound. For example: “Wake up! You have an exam at 9 am!”

- How does the LED light function before sleeping?
The LED acts as a reading light with adjustable brightness that gradually dims as the user falls asleep. - Can the system wake me up before my set alarm time?
Yes, if the accelerometer detects light sleep within a specific window before the set time, it will wake the user early. - What component is placed under the pillow to help wake the user?
A vibrate motor is placed under the pillow to start working when the alarm begins. - How does the active Snooze mode differ from normal clocks?
It uses the accelerometer to keep detecting if the user is still on bed by tracking movement after the alarm time passes. - What can I do if I miss important events due to oversleeping?
You can record sentences like Wake up! You have an exam at 9 am! to use as your alarm sound. - Does the light brightness change in the morning?
Yes, the brightness gradually increases before the set wake up time to simulate the sunrise. - Where should the accelerometer be positioned?
The accelerometer will be put on the bed or under the pillow to monitor moving patterns. - Is the LED light timing adjustable?
Yes, the lightness is adjustable and can be timed to gradually dim as the user falls asleep.
