We are limited to just a few pins on the Raspberry Pi to drive NeoPixel strips (D10, D12, D18 and D21). You can see the white wire is our control line (D18) and the black is our shared ground. The other red/black wire of the NeoPixel strips can go right into the marked +/- barrel jack terminal block. That is it. We are wired up. This wiring will work on all releases to date of Raspberry Pi v1, v2, v3 and Zero.
The 10A power supply will connect to the female barrel jack and the female NeoPixel header will connect to our GND and GPIO #18 on the Cobbler Plus breadboard.
