I want to creted the clock using 8x8 WS2812 LED matrixes.

To make this clock a bit more unusual I want to add sool digit transformations when the time changes.

Currently I am working on a single digit and writing the code.

Second step would be to create custom PCB to connect all components. The last one would be putting it all together. So this post would be updated as I go along.

EXPANDED TECHNICAL DETAILS

High-Visibility Temporal Visualization

The "Final Countdown" project provides a large, bright digital timer designed for high-pressure scenarios like escape rooms or competitive games.

• Dynamic Character Rendering: Instead of just text, the Arduino renders large, stylized digits across the 8x8 LED matrix. The firmware uses a "Scrolling" algorithm to transition between numbers, ensuring a smooth, high-energy visual effect.
• Precise Timer Counter: Uses the Arduino's internal Timer1 hardware interrupt to track seconds with millisecond precision, ensuring the countdown is accurate even if the main loop is handling other game logic.

Game Mechanics

• End-of-Time Alert: Integrated with a high-volume buzzer, the system increases its "Beep" frequency as the timer approaches zero, culminating in a long "Fail" tone when the countdown finishes.
