Hi, I'm Matt and I'm here with my buddy James. We created a working model vending machine out of Lego Dacta parts. We had many bumps along the way in making our vending machine. First, it took forever to mke it. When we were finally done we had used most of our total working time. Secondly, after we had built it we then had to program it. We didn't know how to program it at first, but we looked at someone else's programming before we did anything. So, even though we don't know their names, we owe a lot to them. After we did our programming, we had a lot of bugs to exterminate. The only signifigant one was the fact that it kept giving us too many yellow ice creams. We fixed that and then I did a few...modificatons. I piggybacked a sound generator on the blue light and the yellow light and a fan on the green light so that when you push the button, it turns on the fan,then it gives you the ice cream bar of your choice. We finally got everything fixed and then we played with our new vending machine for a while. After that we said, "Aw, Man",and got to work writting this. Our vending machine works very well now,but we couldn't quite figure out the purpose of the angle sensors because we didn't really know how to use them. However, when I changed the programming to incorporate the angle sensors I saw the numbers changing as the motors moved. My friend James and I both think that this is a really cool project and we hope that you do too.
Below is a picture and the programming.
