The Automated Beverage DispenserTeam Members:Michael Everhart David Castellani Conclusions: 1) Upon completion of our device, all of the components we used were adequate for use and capable of performing the required task. The display was capable of showing the information we needed and the ranger, despite numerous problems, was capable to provide accurate enough data to determine the level of the water. 2) No, the processing power provided by the MPC823 was more than sufficient for our project. One thing that would have been useful would have been a dedicated PWM generation module, like that found on the MPC555. This would have made controlling the servos much less complicated. 3) Slightly stronger servos would have proved useful considering that the current ones we used were barely capable of holding the weight we wanted them to. A less broad pulse from the sonar ranger(or a focusing cone) would have made it a lot easier to deal with. Also, considering what we know now about the display, we would have not spent the large amount of time attempting to read the status bits from it, and would have instead used the delay timer solution that we ended up with.
