Abstract: This paper discusses the design and prototype development of a microcontroller-based Denary Wake-up and Send-to-sleep System, which promotes healthy sleeping lifestyle. Today, the pace of life is increasing with technological advancement which lead to many people feeling the pressure or stress. The design of the system is hoped to wake people up naturally instead of the noisy sound of normal alarm which may cause feel of depression and stress in the morning. On the other hand, the heavy sleepers have difficulty waking up when a normal alarm clock sounds. Hence, the purpose of this system is to wake people in time with more effective and natural method. This paper proposes a system to use light stimulation and pillow shaker together with the sound of alarm to wake people up. An extra function which is solving a task to turn off the alarm is implemented in this system to ensure that the sleeper will be fully awaked. Additionally, this system is enhanced with features to help people fall asleep which are night light, dimming light and starry light projection on the ceiling. The microcontroller used in this system is Arduino Mega 2560 which will read the input value from the push buttons and rotary encoder to give instruction to the output components for the system operation. The Arduino integrated development environment (IDE) is the platform used to write the program which can be uploaded to the Arduino Mega 2560 board.
