0-9999 seconds count down timer using PIC12F683 microcontroller

The goal of this project is to construct a simple 0-9999 seconds count down timer with an alarm and a display. The time is set through two tact switches and the count down seconds are displayed on a 4-digit seven segment LED display. The project uses PIC12F683 microcontroller for all I/O and timing operations and MAX7219 IC for driving the seven segment LED module. The time out condition is indicated by an ...

Countdown Timer using PIC16F84 microcontroller

It's a kitchen timer. Use it to time spaghetti, or maybe an egg. It uses two PICs, one acts as a keyboard encoder, the other drives the display and supports the timer functions. You key in the desired time and press '#'. It's accurate to 1/100th of a second, which can make all the difference I'm sure you'll agree. You can buy something similar to this from Denkimono. Operation: The PIC16F84 doesn't have eno ...
