Can anyone help me?
im trying to build a countdown timer that will trigger a system when the time reaches 0.
requirements:
1. 1 seven segment for the hours and 2 7-segment display for the minutes.
2. the maximum time will be 8 hours
3. there is 1 switch to adjust the desired time in hours
ex: 5 hours, 7 hours
4. a RESET button, that when pressed, the count will stop and the time goes back to the default time which is 8 hours.
5. an LED will turn on when the count reaches 0:00
what PIC microcontroller should i use for this project.
