* Connect '''Vdd''' to the power supply, 3V or 5V is fine. Use the same voltage that the microcontroller logic is based off of. For most Arduinos, that is 5V
* Connect '''GND''' to common power/data ground
* Connect the '''SCL''' pin to the I2C clock '''SCL''' pin on your Arduino. On an UNO & '328 based Arduino, this is also known as '''A5''', on a Mega it is also known as '''digital 21''' and on a Leonardo/Micro, '''digital 3'''
* Connect the '''SDA''' pin to the I2C data '''SDA''' pin on your Arduino. On an UNO & '328 based Arduino, this is also known as '''A4''', on a Mega it is also known as '''digital 20''' and on a Leonardo/Micro, '''digital 2'''
The MCP9808 has a default I2C address of '''0x18''' but you can set the address to any of 8 values between 0x18 and 0x1F so you can have up to 8 of these sensors all sharing the same SCL/SDA pins.
