Chain another pixel to the first! Use another short wire to connect the pad on the first pixel marked with an outward-pointing arrow to the inward-pointing arrow on the second pixel with the same wire wrapping technique used throughout.
Connect the + and - pads on the second pixel with the power and ground wires trailing off of the first pixel.
Add a third pixel in the same manner as the second. I connected the third pixel's ground (-) to the FLORA's GND pad to anchor the curved design, but it can also be connected to the second pixel's ground (-) pad.
You're done wiring! This is just one way to arrange the pixels. Make the design your own! You can use more or fewer pixels and have them arranged in any linear fashion you like.
