I wanted to build a clock as simple as possible : built around a little 18 pins PIC no 7 segment display, only LEDs no decoder, no buffer, no driver for the LED display a cheap temperature sensor The solution of direct LED driving comes from a Microchip Application Note AN234, and as I’m using 25 […]

A Digital Clock can be made easily by using PIC Microcontroller, DS1307 and a 16×2 LCD. I have already posted about Interfacing DS1307 RTC with PIC Microcontroller. The DS1307 RTC can work either in 24-hour mode or 12-hour mode with AM/PM indicator. It automatically adjusts for months fewer than 31 days including leap year compensation

I had some beef with my (very) old alarm clock. It had a radio which was nice to wake up to, but two problems: 1) I would be in bed and think “Wait, did I set the alarm?” I would have to get up, turn on the light and look at the position of the

This device uses two digital sensors (DS1620 or DS1820), measures the ambient temperature with 0,1 °C (0,2 °F) resolution and displays it on LCD 2×16 (LM016 etc.) screen. It have a clock, which is based on DS1302 timekeeping chip. This chip stores current date and time. The main CPU used in this project is PIC16F877.

Description: The clock is synchronised via the German time signal DCF77. It has a display with automatic brightness control and a RS232 computer interface. Design Overview: The clock is built around a PIC16F84 microcontroller from Microchip. I chose this microcontroller since its FLASH memory is easy to program and assembler and programmer software is freely

Based on the idea from http://www.josepino.com/pic_projects/?timebaseI have created a 1Hz Clock Generator. I use PIC12F675 as it’s available locally. Its price is just about US$1. The concept is using 32.768kHz crystal as a clock for the PIC. Therefor, the internal instruction clock is 32768/4 = 8192 Hz. By using the 16 bit Timer1 to count

Wooden LED clock I really like concept. So many different types of wooden clock have been already built. I’ve seen many of them but I still don’t have my own. What a shame. I’m going to fix it right now. Project is very simple and requires only few common wooden materials and hand tools. Well,

A digital LED clock inspired by the building at 200 Water Street in Manhattan, that automatically synchronizes with the 60 kHz WWVB Signal. High Level Design Rationale: The purpose of this project was to design a digital LED clock influenced by the large clock on the building at 200 Water Street in lower Manhattan. Jason

In any advance project we need real time clock synchronize with our work and for this purpose the best option is DS1307 (RTC Ic). Interfacing DS1307 Real time clock with PIC16f877 is done by I2C communication. To know I2C protocol you may refer my previous post “Interfacing external EEPROM with PIC Microcontroller”. To know about
