ABSTRACT:

The digital stop watch with an LCD display is used to measure the time required for a particular event. This watch is quite different compared with  other clocks in many ways  This watch needs much more accuracy than the normal clocks.  This project uses an ATmega328 microcontroller to control the stop watch, by which perfect accuracy can be ensured. Here, PonyProg and AVR studio were used to compile the C and loading the .Hex file into the microcontroller. The stop watch comprises of two different timing modes such as lap timing and split timing.
