I conceptualized an adaptation of the three-wheeler (from the basic kit manual) as a cat toy/feeder. I used
the light light sensor and bar graph to activate the toy when the sun
comes up in the morning. Once activated due to the sun, the engine
moves and the LED in the feathered tail would light up. The moving
device with the trailing feathers and LED encourages my cat to
chase it, hence getting a little exercise prior to catching the reward
of her cat food situated on the truck bed. Her body covers the
light sensor causing it to stop and giving her a chance to eat. From the basics kit I connected the power source into the light sensor (so the moving toy + feeder would be activated in the morning) into the bargraph (to evaluate if enough light is being used) connected via wires to the motor below the body which connected, via the wires, to the LED light in the tail trailing behind.
