I checked with tat code only....it shows this error...can u send me the link to download tat library fi

Please anybody help me regarding checking RTC DS1307 with Arduino

 

[Ian Rogers]

I use a shield.... Its a complete datalogging shield with everything you need on..
**broken link removed**

This has all the libraries already written with examples... This will do exactly what you want!!!

 

[kubeek]

....it shows this error...

WHAT is "this" error? We cannot read minds, and even if we could I doubt we would use this skill to explain to people what they actually meant.

 

[BioniC187]

He is referring to the previous error posted - I assume

 

[M. Tamilarasan]

I brought RTC board(DS1307) ..please help work this kit with Arduino UNO and also to set the current time and date...i'm unable to find correct library

 

[BioniC187]

The library is freely available, just type it into google. Check the arduino cc links

Remember to set the seconds to 0.. Or the ds1307 won't start!!

If you go onto the arduino tutorials here.. https://tronixstuff.com/tutorials/ You will find EVERYTHING you need....

Thank you for ur valuable info....!!!

I bought RTC DS1307 with EEPROM module....i connected with arduino and tried but i faced one issue..after the clock sets the time starts to running only when the external power in available...but when we turn off the external power the where the clocks stops tat Time will be stored...the CMOS battery fixed with module unable to run the time continously without external power..please anybody help with coding

 

[M. Tamilarasan]

please help me regarding using RTC with EEPROM module

 

[tunedwolf]

I'm not sure it's a coding issue. The DS1307 requires a 3V back up battery/ supply for the clock, it will not run unless this supply is available. Check pin 3 on the DS1307 and make sure it has 3v on it when the main supply has been removed.

 

[M. Tamilarasan]

ya i checked the backup power.....Please post the example coding to test RTC with arduino....i'm unable to find the exact coding..

 

[M. Tamilarasan]

what is the name of the connector used to connect the burg strip in controller board to share the same pin.......

 

[M. Tamilarasan]

I bought RTC with EEPROM module from NSK electronics...i tried to set time and date...after that the date and time starts to run...but when we turn off the External power the date and time gets reset...it's not continuing with CMOS cell power..please anybody help me to solve this with coding...
Thanks in advance!!

 

[Ian Rogers]

Which device? Is it a ds1307?

 

[M. Tamilarasan]

Yes....RTC DS1307 with EEPROM AT24C52

 

[Ian Rogers]

Is your cell a 3v cell if its a 1.5v it wont work...

 

[M. Tamilarasan]

Its a 3v cell.....i tried all the example programs given in hardware libraries, after the execution of program the time and date sets but when the external power is turned off means the date and time gets reset.. this is my exact problem...please help me with solution...

 

[Ian Rogers]

You couldn't show me the exact example you are using... Some examples set the same time each time you power up!!
