1.0 Connecting your SmartBar to your Model C, or Raspberry Pi.

The SmartBar comes with a black cable that will plug into the back of your SmartBar, on the rear left or rear right pins.  The eight pin header are both the same, so you can connect to either side of the Smart Bar.   On the rear of the Model C,  you have a black rubber cap, that can be removed to connect you Model C to your Smart Bar.   To connect with the proper orientation, you will need to have the white maker on the end of the cable facing the same direction.  Both have to be facing up, or both can be facing down.

If you SmartBar is connected properly, you will see a bright blue LED lit on the right side of the SmartBar inside the case.  If the blue LED is lit,  you have the cable oriented in the right direction.

1.1 Smart Bar PCB

There are 5 I2C bus pins, which are marked on the PCB and there are 4 GPIO pin headers.  The next section will show how to wire the different style sensor to the header pins.
