Take a moment to review the components in the circuit diagram. This illustration is meant for referencing wired connections - The length of wire, position and size of components are not exact.
The servo plugs into the headers with the ground positioned close to the center of the board.
Side Light NeoPixel Strip:
The Side Light NeoPixel strip connects to the NeoPixel terminal on the Crickit. Din on the NeoPixel strip connects to the arrow icon on the terminal on the Crickit on the Crickit. GND connects to GND and 5V to 5V.
The 4xAA battery case connects to the Power input on the Crickit. We added an on and off push button in between the battery pack and the barrel. We used a JST 2-pin Extension Cable with On/Off Switch - JST PH2 but any on / off switch will work.
