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]

This is LCD Clock/Calendar based on PIC16F628.Time and date are displayed on LCD 1×16 in format HH:MM:SSx mmm dd, where: HH = Hours MM = Minutes SS = Seconds x = AM/PM mmm = Month (Jan, Feb, Mar) dd = Day.[more]

The projet built using the OOPIC microcontroller.Features:
- Each day of the week can be set independently to any of 4 times or disabled
- Crescendo alarm (starts soft and gets louder until you wake-up).
- Each day’s alarm can be set to skip one week, alarm resumes the next week.
- Each day’s alarm can be set to a different time for one week, alarm resumes normal time the next week.

This is a digital clock and temperature display which is alernate display between time and temperature.Here are some features:
- Display time 24-hour format. 00:00 - 23:00
- Use DS1307 RTC with 3V betterry back-up.
- 1 channel temperature sensor(DS1820)
- measures temperatures from -55 to + 125 degree Celsius.
- Temperature accuracy 0.5 ‘C
- software compiled with CCS C compiler V 3.222

This is a nice analog clock based on PIC16F84.The meter control by pulse width modulation (PWM). It consists of three analog meters with scales that went from 1-12, 0-59, and 0-59 and indicated hours, minutes, and seconds respectively.[more]
