PIC16F84 Alarm Clock

PIC16F84 Alarm Clock

This is an alarm clock I built. It worked very well in the short time I used it because I programmed it to play a very annoying tune through the speaker. I actually started waking up before the alarm went off, so no one else in the house was woken up by its annoying tone. The Jal source code can be found on my download page.

characteristic

* Use the PIC's timer0 interrupt for time preservation

* 4x20 HD44780 compatible backlit LCD for displaying the time in large digits (4x4 and 4x3)

* Alarm sound tone using PWM

* A computer interface used for synchronizing time with the network.

* (Possible battery backup (in case of power failure...))
