Design and Manufacture a Smart Reminder Device based on Arduino Mega to Inform Patients for Taking Accurate and Timely of Medical Drug

One of the major challenges in the successful treatment of many diseases is the non-adherence of patients to taking medicines on time, which can have serious consequences. Age is associated with a decrease in memory and vision. Also, a person may suffer from dementia such as Alzheimer's or other diseases, all of which require medication, and this is difficult for them. Due to the busyness of life, the use of medicines, especially important medicines, may not be managed in terms of time. In this article, we will design and build a medication reminder device using the Arduino Mega board. This device can store and manage up to 20 reminders per day. The user can set the reminder times in the program and view them through an LCD screen. At the appointed time, the device reminds the user when to take the medicine by turning on the built-in LED and sounding the buzzer.
