Sometimes patients forget to take the medicine at the required time of medicines. And sometimes patient also forgets which medicine He/She have to take at required time. And it is difficult for Doctor/Compounder to monitor patients around the clock. To avoid this problem, we have made this medicine reminder system for patients using Arduino.
n this system we have used Arduino for controlling the whole system. Working of this project is very simple. In this system ds1307 real time clock chip is used for running the time accurate and to prevent the time after light failure by using 3 volt li-on battery connected with this real time clock chip at pin number 3.
SDA and SCK pin of real time clock chip is directly connected with SDA and SCK pin of Arduino (A5 and A4) respectively. These two pins should bepull-up using 10K resistor.
When we start this system real time clock runs the time on 16×2 LCD. And if we want to set alarm time for medication we have to press set_mad buttons which is connected with pin number 8 of arduino. After pressing this button LCD shows Set Time 1. And then we can selects the time as we want to set for medication by using INC and Next button which is connected to pin 9 and 10 respectively of arduino. After set time 1, LCD shows set Time 2. Now using previous process set the time again. And after second time set, LCD shows again set time 3. And set this time like previous. In this system “Group medicine” indication (take group 1 medicine, take group 2 medicine and take group 3 medicine) is used instead of medicine name. When any alarm occurs LCD indicates Group medicine 1, Group medicine 2, Group medicine 3.
