Coin Counter: "Bright Box"

Our final concept is a our coin counter that encourages children to set saving goals by rewarding them with a short light show each time they reach a goal of 1, 3, and 5 dollars. There are four rectangular slots at the top of the box. Each slot counts 1, 5, 10, and 25 cents to coordinate with a penny, nickel, dime and quarter. Once you reach your goal, the lights in the box will light up and the light show will get longer as the amount collected in the box increases. Once you have reached your final goal you can lift up the lid and collect your money. The video, hero shots, and code are posted below.
