Hi, I understand that the I2C pins on an Arduino Uno are A4 and A5. Now I already use the A-pins for an 16x2 LCD display, and the layout of my project does not make it easy to change that. Still I would want to attach a RTC clock to the project but only D0 and D1 are free.
Seeing that you can daisychain several I2C shields on those two pins, I wonder if I can share the LCD and the RTC on A4 and A5. Alternatively, is it possible to commandeer the D0 and D1 pins for the RTC?
