d) Stopwatch / Timer - Using the ATmega32A timers, develop a stopwatch / timer application with the input taken form the membrane / matrix keypad. The LEDs should act as a display to indicate the time remaining or elapsed. As the timer is nearing completion, the LEDs should flash and then remain fully on when the timer expires. The timer should accept minutes and seconds as inputs. The value of the timer could also be displayed on the LEDs as it is entered or the system is paused. One of the keypad switches could be used to switch between timer and stopwatch modes
