Building a device that clips to your belt and tracks how much time you spend inside and outside


Step 8: Connect Accelerometer

We will now connect the accelerometer to the Uno.  As we only have one 3.3V connection we pull the power cable across the Uno to reduce the amount of soldering required.  Digital 2 will power the accelerometer.  The ground will go to the 2nd ground below the 5V pin. The X, Y and  Z cables all go to Analog 0, 1, and 2 pins.  

We then turn the accelerometer such that we can lay it along the Uno/Shield on the side of the analog pins.  If the wires are too long, we can trim them down and re-strip as needed to prevent too much excess wiring within the case.
