LED Clock with DS3231 and FastLED

This project is an LED-based clock using the DS3231 RTC (Real-Time Clock) module and WS2811 LEDs controlled by the FastLED library. The time is displayed using four separate segments, each representing a digit of the hour and minute.

Features

• Displays time in HH:MM format using LED strips.
• Uses the DS3231 RTC for accurate timekeeping.
• LED brightness can be adjusted through code.
• LED patterns are defined for digits 0-9.

Hardware Requirements

• Arduino (e.g., Arduino Uno)
• DS3231 RTC Module
• WS2811 LED Strips (4 strips with 14 LEDs each)
• Resistors, Wires, and Breadboard
• Power Supply (depending on the number of LEDs)

Software Requirements

• Arduino IDE with FastLED library installed.
• Wire library (included in the Arduino IDE).

Circuit Diagram

Connect the LED strips to the designated pins on the Arduino and wire the DS3231 module according to the following table:

Component	Arduino Pin
LED Strip 1	Pin 3
LED Strip 2	Pin 5
LED Strip 3	Pin 6
LED Strip 4	Pin 9
DS3231 SDA	A4
DS3231 SCL	A5
Status LED	Pin 13
