This repository contains the design and implementation details of a multifunctional digital clock, utilizing the TM4C microcontroller as its core processing unit. This project aims to blend traditional timekeeping with modern technological enhancements.
The goal of the TimeSync project was to design and implement a multifunctional digital clock using the TM4C123GH6PM microcontroller. This clock includes a timer, display, temperature sensor, and an alarm feature that triggers an mp3 module using UART. Users interact through a modern OLED display and 3 push buttons for functionalities such as switching between the clock and temperature display.
