Google. Research how digital clocks work. Look for digital watch circuits and datasheets for rtc chips. When you know how a hardware digital clock works you can look at how to simulate one in software.

About 4 years back, while building one of my digital alarm clock using microcontroller, even I use to think that using rtc chip is a waste when it can be done using precised timer interrupts . But when I actually did it using only uC, I found the reason why we should use (...)
Hi, I am making a digital clock using the 8051 micro and the DS12887 rtc chip. I want to know how to turn off the daily alarm. As it happens, there would be *some* value within the alarms registers. That would cause the alarm to go off at that point of time, once a day. Even 0x00 would be valid in this case. In order to (...)
hi all, i need to make a digital clock by using 8051 microcontroller in assembler and the display is seven segment not LCD no decoders used there are 3 switches : 1- one for modes ( hours,minutes and seconds) 2- the second for alarm 3- and the other for stop watch if possible Any ideas? thanks.
I have made a gaint digital LED clock based on 89S52 assembly, every thing is working perfectly but I dont know why the time is running very fast in rtc. Just in 42 seconds it completes one minute. Although I m using rtc in correct order. Same circuit when I check on vera (project) board it works fine with (...)
Sir iam sending the circuit diagram of digital alrm clock using ds 1307. but i require code for this please send me the
Hi, im trying to make a digital clock using 8051 & 16x2 LCD...I know that a lot these projects would be find once googled...but was trying to make it by my own as a beginner...What i do is to generate a 1 sec delay using interrupts....& in waiting time between these interrupts i print the seconds minutes & hours on (...)
The ready made clock chips available, usually use mains frequency as refernce and thus the accuracy highly depends on the same. But you can get dead accuracy with rtc interfaced with a microcontroller. But In the DS1307 as it uses external cylinderical crystal, the accuracy may not be guaranteed. But using a DS12887 module accurate time can (...)

use a timer interrupt(set it at 5) for 12hrs.. it will simply flip the previous state..if it was on at 5am then it will gt switched off at 5pm..and so on.. or u may use real time clock and then then check the data and make the further program .... I agree with beyondH. In your case wanditea
First read I2C protocol and datasheet of PIC16F877 its all about there then after understanding the concept of I2C it will become easy for you to write codes for digital clock. For a short time you can use I2C libraries also which has fully working codes. Interfacing is quite easy see the link.
Hi, I am in search of low cost Powerline communication circuit/modem through which i would like to transfer Time information(rtc) including seconds from a master clock to many receiver within a building! So it would be around totally 8 bytes of information including other miscellaneous alerts every second. Also it is better if the circuit or mo
Dhaka, assembly language is not suitable for develop serious projects like digital clock, I strongly recommend to switch on "C", probably MicroC from mikroe.com, you have working example with total explanation... best regards
Hi, I am doing a digital Timer using AT89C4051 and DS1307 rtc. Time is displayed on 16x2 LCD. I have enabled 1 HZ square wave output and updating the time on LCD every rising edge. The problem i am facing is the rtc time is not accurate. For every 24 hours i observed a delay of 2 minutes. I have assembled two other (...)

Hi. I really had a hard time understanding the TMR0 interrupt of PIC16F84A (4MHz crystal). I'm using PICBasic. Is there anyone who could give just a simple demonstration on how to program interrupts, including the prescaler configurations. I'm building a simple digital clock with 6 CA 7-segment displays, with 3 buttons. I'm very much (...)
Hi, I have been prototyping a small project of mine based on the AT89S52 for sometime now. Now as I am nearing completion I am thinking of the power consumption issues I might have with the finished stuff, which will run on battery power. Till now, I was prototyping using an evaluation board which runs on a 5 VDC power supply. So I did not ha

Hello all, I am currently working on PIC16F1937 . My project is digital clock alarm with several additional features...Due to cost issue instead of using rtc Chip, I am using 32.768KHz as Timer-1 external crystal oscillator to increment time of digital clock and 4 (...)
Can anyone help me with this fm projects it's in Italian and source code is so complicated and i cant converted to hex file .... please help
In digital system, all data is 0 or 1. Where is the source for seed of the random number generator? We have tried using meta-stable to generate the seed. You also can use rtc (real time clock) input, since each time the time input will be different. For asic without rtc, you can think about other idea (...)
