From the project

This project implements a 60-minute countdown timer using classic discrete components. It demonstrates fundamental hardware design principles, including clock generation, cascading counters, 7-segment display driving, and simple logic implementation for alarm triggering.

Welcome to the 60-Minute Pomodoro Timer project! This repository contains the complete Printed Circuit Board (PCB) design for a hardware-based Pomodoro timer, developed as a comprehensive PCB design task.

The design is optimized for a double-layer PCB, strictly adhering to standard design rules (DRC) and professional routing techniques (e.g., 45-degree routing, proper via usage).
