Checkout Scanner

This little machine acts like an optical scanner at a store where you scan and pay for your items. You can scan your LEGO motors, wheels, red ball, and a few small items representing cakes, veggies, and a fork. When you're done shopping, scan your black and yellow "credit card" and the scanner will display a list of all of the items you scanned and a total price.

The program is designed to recognize the following parts and objects from your kit based on their color:

  • Motors (white) $10

  • Wheels (black) $5

  • Ball (red) $4

  • Cakes (teal) $3

  • Veggies (green) $1

  • Fork (blue) $2

  • Credit Card (yellow) checks out
