Summary of LCD STOPWATCH COUNTDOWN COUNTER CIRCUIT WITH PIC16F877 PICBASIC PRO

This project implements a stopwatch and countdown timer using a PIC16F877 microcontroller with an LCD display. The system utilizes TMR0 interrupts for accurate timekeeping and was designed using Proteus ISIS for simulation and ARES for PCB layout, with code written in PicBasic Pro. It features five buttons for menu navigation, value adjustment, confirmation, start/stop/resume control, and resetting the timer to zero.

Parts used in the LCD Stopwatch Countdown Counter Circuit:

  • PIC 16F877 microcontroller
  • Liquid Crystal Display (LCD)
  • TMR0 interrupt module
  • Five function buttons
  • Proteus ISIS software
  • Proteus ARES program
  • PicBasic Pro source files
