hello again do I need the pull up resistors when connecting to uno R3 I just got the chronodot and am going to see if this works
Yes. The Chronodot has locations where they can be installed, or they can be placed elsewhere on the I2C bus. Anything between 2.2K and 10K should work. Actually it may work without them, as the Wire library enables the internal AVR pullups, but they are technically a little weak for I2C, so I always use external pullups.
