Modern day-to-day life of people in major cities is very demanding and the schedules are equally hectic. In such times, it is practically impossible to keep a track of all the activities/ appointments. Many a times, it happens that we may miss an important task; for example: taking medicines, attending a meeting, returning library books, paying the bills etc. And this cycle can keep going on endlessly. The human mind is not designed to multitask, it needs to work things out one at a time. This requires us to maintain our focus on the task at hand, and as a result other important things take a backstage and some may even slip out of our minds. In order to address this problem, we have come up with a Weekly Task Alerting System. This system is designed to alert the user of all the important tasks that are due on a specific day, every week. So now, the user can carry on with his/her life without any worries. This circuit can count the days. The rising of the Sun is detected by a light sensor. The voltage level at gate connected to it goes low. Due to this, output also goes high which eventually makes the counter IC advance by one count. This way each day is counted. Similarly, the counter advances by one every morning until it counts seven days. An Astable Multivibrator produces 2Hz frequency to flash LED as a reminder. The LED flashes until the reset switch is pressed momentarily. When the counter IC resets, its output becomes low and it’s ready to begin day counting for the next week.
