Cronometro con PIC / Start stopwatch using microcontroller

Digital stopwatch using microcontroller
How much time this event will take to finish?OK, Let's countdown the time.So a stopwatch is the best solution.Just press the start button to start countdown then stop when the event completed.Now every cellphone has this feature but i was determined to make a digital stopwatch using micro controller as I am very fond of  this type of works. This project is about to make a digital stopwatch. Whole project is simulated in Proteus 7. MikroC is used to write the code.
This video demonstrates the project:
The circuit is easy and we just need
  • PIC16F73(1pc)
  • 16x2 LCD(1pc)
  • Push Button(3pc)
  • 20 MHZ Oscillator(1pc)
Here we use three buttons.
  1. START Button
  2. PAUSE Button
  3. STOP Button
To understand the whole project look at the final output of the project.
Just make the connections as the figure shown.
This project file is compiled in MikroC Pro 5.8.0.
You need the hex file and I share whole project code. You can download from here.
Figures below are shown, is captured from proteus 7 professional.

After pressing STOP Button stopwatch is cleared.
Connection Detail:
  • PIC RB2 ---- LCD RS
  • PIC RB3 ---- LCD EN
  • PIC RB4---- LCD D4
  • PIC RB5----LCD D5
  • PIC RB6----LCD D6
  • PIC RB7----LCD D7
  • PIC VCC  5V

Now just take breadboard and make connections. Download the HEX file from here.

Load the HEX file to the pic microcontroller.

Give power to the board and press the buttons to see the output in LCD.

Any Complexity ? Or Facing Problem ?? Just put comment. I shall try to help.

As I have shared the whole project code you can modify the code in MikroC as you need. Download all necessary files including schematic, code from below.
