Story
In this new article, we are going to make a very useful project which is known as the medicine reminder project. This project can help people who are taking medicine. This is basically a box with some drawers. there are 3 drawers which can open and close.
These days many individuals have medication that is endorsed for requiring some investment and it is vital. thus, we have made this marvelous medication update project with the assistance of Arduino. We need to set the medication update once then it will naturally remind the medication by opening and shutting the cabinet of medication likewise a ringer is there.
The medicine reminder project is very important for a patient who is having regular and timely prescribed medicine. Our Automatic medicine reminder using Arduino project is similar to the alarm system. which additionally shows you the medication name. commonly we neglected to take the medication which isn't really great for a portion of the illnesses so, this kind of project can help a lot in that case. Medicine reminder has an LCD that shows you the name of the medicine to be taken at which time and also.
Working of Medicine Reminder
There are 4 push buttons in the Medicine reminder Arduino project one is for + in time like in hours and minutes. the second button will shift the cursor to the next option. if you are adding in an hour then after pressing the second button the cursor will shift to the next digit which is the minute.
I have completed this project with PCB which is easy. PCBWAY help me to complete my project.
presently the third button will save the progressions and begin the update. Presently, when we start the framework the Presentation of the task will incite and request "Set update ". there are four buttons when you press the main button it will begin the time setting. presently when it will arrive at the client's characterized time the ringer will begin for 30 seconds.
