It's time to connect the electronics to the CPX, then finish the body by hooking the servo to the front of the cardboard body.
Plug the JST battery connector into the Circuit Playground Express black battery connector.
Tip: If you need to unplug the JST connector, be careful not to pull too hard or the wires may break. Wiggle it gently while sliding it slowly out.
The servo has three wires joined to a 3-pin female connector. Plug the male header pins on the ends of the alligator clip wires into this connector. To avoid confusion, choose wires that match the color of the servo wires.
A simple way to remember this:
Don't forget, you can remove and reposition the Circuit Playground Express to keep the wires out of the way.
Unbend a paperclip in the middle and straighten it out. The larger end will go towards the front.
Fold the front and back of the Inchworm together, and mark a spot on the front roughly even with the arm. Insert the larger end of the paperclip through the spot.
Insert the end of the smaller loop through the last hole in the servo arm.
With the paperclip attached at both ends, check to see that the Inchworm is as open as you would like it to be.
Then bend the ends to keep them from slipping out.
