This project implements a stopwatch application using an ARM microprocessor Tiva-C Series TM4C123GH6PM. The stopwatch is controlled through switch inputs and displayed on an LCD screen. It was developed using Code Composer Studio and created as a hands-on project for EME Egypt's Make Electronics course to demonstrate interfacing with LCD and using the timers module on the microprocessor. 🕒
Start, pause, and reset the stopwatch using physical buttons. 🚀
Display the elapsed time in the format "HH:MM:SS.m" on an LCD screen. 🕐
