Abstract

In our day to day life, timer and alarm plays an important role. Usually in timers, if the user does not reset the device, again and again it disturbs the user. In this project, the device operates a light and alarm in a controlled manner.

This project automatically switches on or switch off the alarm and light according to the desire of the user. The user can simply set the timings and duration of the particular alarm and light.

Initially the user has to set the timings. When the particular time is reached, the alarm will be on. The user has to reset the device. Again after the particular time is reached, the alarm will be on.

Again the user has to reset the device. Again after the particular time is reached, the alarm will be on and this process is continued. If the user fails to reset the device for particular number of times, the alarm and the light will be switched off automatically. This shows the user will be in deep sleep.
