Bring your needle through the back of the fabric to the front next to the GND pad on your Flora. Leave a the last few inches as a tail on the back side of the fabric. |
|
|
Stitch a few times around the GND pad and end on the back side of the fabric. Tie the tail and the working thread into a square knot, tight against the fabric. |
|
|
Dab a little Fray Check or clear nail polish on the knot while holding it tight. This will prevent the knot from coming undone and creating unwanted shorts in your circuit. Trim the tail very close to the knot. |

Stitch a path over to the gnd pad on the Flora accelerometer. When you get there, stitch a few times around the sensor's gnd pad. |
|
|
On the back side of the fabric, slip the needle through the previous stitches and then back through the resulting loop to tie a knot tight to the fabric. Dab on your sealant and trim closely. |
Repeat this process to make the other three required connections to the accelerometer - 3.3v, SCL, and SDA. This is the i2c bus on the Flora, and you can chain more sensors (or LED matrix backpacks) to this first one by connecting to the as-of-now unconnected SDA and SCL pins. i2c is great for this application because you can connect many devices to each other without using up all the pins on the Flora.
