Electronic Clock with Calendar Using 51 Microcontroller and LCD1602 Display (Proteus Simulation + Program + Report + Component List)

Simulation Diagram: Proteus 7.8

Compiler: Keil 4/Keil 5

Programming Language: C

Number: C0002

Main Functions:

1. Uses LCD1602 display, DS1302 records calendar and time.

2. Button settings for date, time, and alarm.

3. When the actual time reaches the set alarm time, the buzzer sounds an alarm.
