It's safe to say that while our project didn't come out exactly how we planned, we are still happy with the finished product and certainly had a lot of fun along the way. In our original design, we had planned to be able to move the cannon from side to side and up and down using a wireless Wii nun chuck. Due to difficulties with both the programming of the wireless nun chuck and weak stepper motors, we were unable to make this a reality. However, we did manage to rig the cannon up to a regular Wii nun chuck, allowing us to fire it by pushing the "C" button on the controller. Since we couldn't get the stepper motors to handle the load necessary to move the cannon, our laser cut part was no longer necessary in order for the cannon to function properly. Perhaps in the future we will be able to find a strong enough motor so that we can aim the cannon better, but that just wasn't possible given the window of time we had to work on the project. Luckily, the cannon does satisfy the most important goal of being able to use it to launch candy into our mouths. Although getting it to fire just right takes a little bit of trial and error, it is all part of the fun and makes actually being able to catch the candy that much better. As soon as the project expo is over, we look forward to applying an excessive amount of pressure to the tank to see just how far our cannon can launch candy.
