INTRODUCTION

The application of Smart Medicine Reminder is very wide and can be used by patients at home, doctors at hospitals and many other places to take medicine on time. We are making a simple Medicine Reminder Using Arduino which reminds us to take medicines 1 or 2 or 3 times a day. The time slot can be selected using push buttons. Also, it shows the current Date and Time.

WORKING AND OUTPUT

Welcome to the Arduino-based project.

The Pill Reminder Alarm is powered using a 5V supply. When it first boots up, it shows a welcome message as “Welcome to HealthcareREES52”. The LCD screen is set to cycle in three screens. The 1^st screen shows a message as “Stay Healthy, Get Well Soon”. The second screen is a help screen which tells to press the push button to select any one-time slot to remind (once/twice/thrice in a day). The time slot is changeable in the program and can be configured accordingly. Right now we have fixed this into three durations i.e. 8 am, 2 pm, and 8 pm.

We have divided time slots into three modes. Mode 1 selects to take medicine once/day at 8 am when the user presses 1^st push button. Mode 2 selects to take medicine twice/day at 8 am and 8 pm when the user presses the 2^nd push button. Mode 3 selects to take medicine thrice/day at 8 am, 2 pm and 8 pm if the user presses the 3^rd push button.

When the user selects desired slots by pressing push buttons, the user input is recorded and the time is taken from RTC. When time is matched with the selected time slot then the buzzer starts buzzing. Users can stop the buzzer by pressing the STOP button. The same process continues for the next slot reminder.
