im working on a simple RTC 1307, like this one u can see in many tutorials. I just want a clock that works a 'tick' more precise than the internal Arduino Uno counter (@atmega328P) but i wont get it. Sitting for the whole day and every time i try a new way its the same, that clock wont run.
I followed that tutorial ( http://www.glacialwanderer.com/hobbyrobotics/?p=12 ) but my clock tells everytime i ask "45:165:85 165/165/165"
Its getting late and im out of ideas, maybe someone nice has a good idea or a similar problem.
P.S. I dont have the Shield RTC, but a DS1307 with 32K Crystal on a breadboard,connected on A4(SDA)/A5(SCL)
