Welcome to the Arduino Digital Clock project.
This repository contains all versions of my digital clock project, from the very first Arduino Uno prototype to future ESP32-based versions.
The goal of this project is not only to build a digital clock, but also to improve it step by step while learning new programming techniques and embedded systems concepts.
✅ Version 1.0.0
Features:
- Arduino Uno
- LCD 16x2
- No RTC module
- Time keeping using millis()
- Time adjustment with two TCRT5000 sensors
- Blinking colon animation
- Hourly LED notification
- Bug fixes
- Code optimization
- Better documentation
- Small feature improvements
- ESP32 support
- Wi-Fi time synchronization (NTP)
- Improved accuracy
- Better startup screen
- Alarm
- Stopwatch
- Countdown timer
- Large LCD font
- OLED display support
- EEPROM time saving
- Better user interface
- Multiple display modes
This repository documents my learning journey in embedded programming.
Every new release introduces improvements, new features, and cleaner code while keeping previous versions available for learning purposes.
