Pop off the servo arm and reorient like in the moving picture above. This is to ensure the servo will pull Adabot correctly to create the waving effect.

In order for Adabot to move side to side, we'll need a force to pull him back after the string attached to the servo loses tension.

Capacitive Touch & Attaching the Truck Top to Base
To control the truck and tell it when to go for a spin, we will create a capacitive touch button on the top of the truck. Each time the foil is touched, Adabot will wave with some ice cream and the truck will go for a spin around the block!

Adding NeoPixel Lights
To create an under glow effect for the truck, use duct tape to attach NeoPixels to the bottom of the truck. Be careful the NeoPixel strip does not to come in contact with any moving parts from the motors or axle.
Now turn on the PowerBoost switch through the back of the truck, touch the foil and watch the glory of the truck!
That's it! Enjoy your new ice cream slingin' truck!
