Project Description:
The basic concept behind the project is to design and implement a
microcontroller based stopwatch using PROTEUS software. The stopwatch is used to
measure the time required for an event. This differs from ordinary clocks in many
ways, one of which is the accuracy of time. The stopwatch requires much more
precision than a normal clock. Here
the 8051 microcontroller is used to control the stopwatch through which accuracy can
be guaranteed.
The input and output circuitry includes switches and a 16x2 Liquid Crystal
Display (LCD) respectively. The functioning of the circuit is described below.The
crystal oscillator is connected between pins 18 and 19 for having clock signal. The
ports 1 and 2 are used for interfacing the 16X2 LCD. When the SPST switch is
pressed after executing the code then the count increments by one and goes on till the
switch is pressed again. Now the count will be stopped and the total time will be
displayed on LCD screen. In order to have make the value stand on the screen for a
long time the delay function is used.
