MicroView -- DS1307 Real Time Clock
Pin 2 SCL -- SCL
Pin 3 SDA -- SDA
Pin 8 GND -- GND
Pin 15 +5V -- +5V
To verify the Real Time Clock chip is correctly hooked-up, run the I2C Scanner sketch. It will show one, two, sometimes three I2C bus addresses in use.
The DS1307 address is 0x68.
Some boards have an EEPROM built on the board The 24C32's address is 0x50.
Some boards also have a DS18B20 one wire interface. Its address is 0x20.
