So, hey guys.
I've been looking for a RTC library so I can use on my "tiny real time clock i2c". I know that is a dumb question for some of you guys, but I don't know where I get this library.
Thank you guys anyway.

Hi, welcome to the forum.

You mean you want a sketch for the DS1307 ?
You can search for : Arduino DS1307
There are many libraries for it. There is also a time library (like the time and date on a computer) that uses the DS1307.

Find something simple to see if it works. Let us know if it works (or not).

When you connect the DS1307, you can use the i2c_scanner to see if the I2C communication is working.

Here's the official I2C library: Wire - Arduino Reference

and the Time library: Arduino Playground - HomePage

Here you can find all you need in one place: DS1307RTC Library, For Accessing Real Time Clock (RTC) Chips

Good luck!

found this the best start for the Tiny RTC

I'm using Arduino UNO and it's nor working. Everything that I use to show the right time on the display is useless. Can someone help me? I just need part of the programation. I'm using Arduino UNO and Tiny RTC I2C. Please, help.

Well you'll need to post the code you've been trying....I have a 1307 and it worked perfectly straight out the box. So post your code and explain what's going wrong. Also provide a schematic of your circuit.

Read reply #3 again, or at least acknowledge that you have specifically tried that to no avail. The way things are, if iou are having all this failure where nobody else does, your softwre could be fine and the problem is most likely due to a bad connection.
