Summary of DS1302 RTC 8051 DIGITAL CLOCK CIRCUIT (LCD DISPLAY)
This article provides an 8051-based digital clock project using a DS1302 RTC and an LCD display, with Keil source code and Proteus ISIS simulation files available for download. Author Aytan ASLAN supplies schematic, code, and simulation archive links for building and testing the clock.
Parts used in the 8051 Digital Clock Project:
- 8051 microcontroller (e.g., AT89S52 or equivalent)
- DS1302 RTC module
- 16x2 LCD display
- Crystal oscillator for 8051 (typically 11.0592 MHz)
- Crystal for DS1302 (32.768 kHz)
- Capacitors for oscillators and decoupling
- Resistors (for LCD contrast and pull-ups as needed)
- Push buttons for setting time (hours/minutes/reset)
- Voltage regulator (e.g., 7805) or 5V power supply
- Backup battery or coin cell for DS1302
- Breadboard or PCB and connecting wires
