This is a web page about a project I did in computer class. I had to make a vending machine out of Legos. I took a long time because of all the pieces that it took to make it. After I finished making it, I programmed it to take Legos as coins and for Lego ice cream to come out. It was hard to find a lego for the coin because some were too big and some were too small, so we used Legos as a credit card. We pulled them out instead of just dropping them in. Below is a picture and the procedures I wrote:
