The objective of the Medicine Reminder Using DS1307 & I2C Protocol project is to remind the medicines to the patients at a regular interval of the time according to the prescription.

Outstanding Features:

1. The medicines are reminded to the patients according to the time & doctor’s prescription.
2. Display of digital clock is made on HD77480U, 8-bit data bus, 2 line Liquid Crystal Display Unit.
3. User can enter & change the medicines dynamically by using 4×3 matrix keypad.
4. DS1307 is incorporated in the project to retain the clock & calendar during power failure.
5. DS1307 is incorporated with power failure detecting circuit to switch on to the battery source whenever external power supply is turned off.
6. I2C (Inter Integrated Circuit) protocol is used as an interfacing standards to conserve the number of port pins during communication between RTC (Real Time Clock) & microcontroller.
7. Hardware is incorporated with set of LED’s representing a specific medicine followed by an alarm circuit for turning on buzzer whenever entered time matches.

Components Used:

1. AT89S52 Microcontroller Unit
2. DC Power Supply Unit
3. LCD Unit
4. 4×3 matrix keypad
5. 12v buzzer
6. LEDs
7. BC547 Transistor.

Software & Tools Used:

1. Embedded C Language
2. Keil – 3 Integrating Development Environment (IDE – Evaluation version)
3. Proteus V7.5 Simulator (Evaluation version)
