This project is a microcontroller project creating an alarm clock with two alarm times using PIC18F4520.There are 5 buttons: mode, hour, minutes, alarm 1 and alarm 2.The output pins from the PIC18F4520 will be connected to a vibrator to create the motion alarm.[more]

The PIC microcontroller is programmed to read the real-time clock using I2C serial communication several times a second and update the display.The PIC performs two other functions; it compares the time against the alarm settings to determine when it should go off and also handles time, date and alarm setting.The design was created using New Wave Concepts’ LiveWire which allows you to simulate the effect of the signals on the components.[more]

Here is a simple PIC16F84A alarm clock. This page summarizes this discussion (in french) in my forum, where Samir (aka numerique1) requested for help to build a weekly alarm clock for his school. Many thanks to him for his tests and patience.This clock counts seconds, minutes, hours and day of the week.Time is displayed on 4 seven segment LED displays.[more]

Joel Avrunin writes:The high-tech student of today has many tools at his disposal for keeping track of his hectic schedule. From computer date books to Palm Pilots, every event can be tracked. But however well organized he is, nothing will help him if he is oversleeps. The alarm on a personal organizer is too quiet, and most alarm clocks offer limited functionality. To solve both problems, we developed an alarm clock for today’s world.Our alarm clock features a large, bright time display, easily visible in the bedroom. It also features a loud, irritating alarm, sure to wake even the soundest of sleepers. By far the most innovative part of the alarm is the LCD display, which gives the date, alarm status, and status for setting the clock.[more]

This is a PIC16F877 based alarm clock designed by Quozl.Here are some features:wakes Quozl up each day, doesn’t wake Quozl’s wife, defaults to wake Quozl up the next day, doesn’t need to be told, can be told at any time in the previous day not to wake Quozl up, can be configured accurately without having to hold buttons down, can emit per-second tick noises, or not, can emit tones in response to key presses, or not, can be told that Quozl is on olidays,changing time for daylight saving can retain minutes and seconds, open source, capable of being further hacked.
