DS1307 Real Time Clock

[VikiBoiUniquez30]

Hi, would you mind sharing the working code ? I have tried all the codes i can find. But unfortunately i'm getting syntax errors. And i always encounter the error message saying that RTC was not declared. It would be great if you can help me out. Thanks a lot!

@cubtastic how do u get 12 hrs mode instead of 24hrs mode?

[2011supra]

@TheBasicStamp There is nothing wrong second delay.

[2011supra]

There is nothing wrong with second delay. I did myself and i solved it to get second accurately.

0:53 lol the seconds change from 13 to 15 and it skips 14!!!

There is one ready solution for Industrial Automation and Machine control - ATmegaPLC4 on YouTube

You can program the DS1307 to output a square wave which can be connected to an interrupt pin on the MCU, which can trigger an interrupt routine to read the time, and display it onto the LCD.

Hi, nice project and you too!!! congratulatios, fron Venezuela

[bertuswoks]

which pins are being used? are d pins the default wire.h pins?

Hi nice project, do you think that a RTC would be a good way to do a chronometer with milliseconds? or there are easier/better ways?

at 1:37 the clock jump from 55 to 57 why?

@falflores

Cause it has somewhere a delay inside the infinite loop that reads,calculate,display the time that needs to be lowered

[TheBasicStamp]

@falflores His program had at least a 1 second delay before refreshing the time, so it skipped 56

@falflores maybe the lcd screen wasn't being actualized fast enough so it is more noticeable when it's not synced

What compiler did you use?

cellphone calls at the end :)
