// Arduino Uno/2009: // ---------------------// DS3231: SDA pin -> Arduino Analog 4 or the dedicated SDA pin //

SCL pin -> Arduino Analog 5 or the dedicated SCL pin

// // Arduino Leonardo: // ---------------------// DS3231: SDA pin -> Arduino Digital 2 or the dedicated SDA pin //

SCL pin -> Arduino Digital 3 or the dedicated SCL pin

// // Arduino Mega: // ---------------------// DS3231: SDA pin -> Arduino Digital 20 (SDA) or the dedicated SDA pin //

SCL pin -> Arduino Digital 21 (SCL) or the dedicated SCL pin

// // Arduino Due: // ---------------------// DS3231: SDA pin -> Arduino Digital 20 (SDA) or the dedicated SDA1 (Digital 70) pin //

SCL pin -> Arduino Digital 21 (SCL) or the dedicated SCL1 (Digital 71) pin

// // The internal pull-up resistors will be activated when using the // hardware I2C interfaces. //

// You can connect the DS3231 to any available pin but if you use any // other than what is described above the library will fall back to // a software-based, TWI-like protocol which will require exclusive access // to the pins used, and you will also have to use appropriate, external // pull-up resistors on the data and clock signals. // http://www.instructables.com/id/Real-time-clock-using-DS3231-EASY/?ALLSTEPS
