Automated Ice Cream Topper

Introduction Controlled by a PIC 32, the automated ice cream topper stores individual ice cream topping preferences, outputting the user’s ideal solid, liquid, and whip cream topping amount with the push of a button. Our project demo can be viewed here:Ā Project Demo. The automatic ice cream topper as demoed had three basic topping capabilities that …

Haptic Feedback Weathervane

Introduction When sailing a boat, one of the most important factors is the direction of the wind. If they want to keep a steady heading, sailors need to be able to dynamically adjust the direction they steer as the wind changes. Unfortunately, the ability to tell exactly which direction the wind is blowing can be …

Touch-A-Sketch

Introduction For our final project, our team built a touch screen controlled Etch-A-Sketch we call Touch-A-Sketch. The Touch-A-Sketch is the first of its kind that allows users to draw on the touchscreen and sketches the drawing on the Etch-A-Sketch by controlling the knobs on either corner of the toy. There are four main components that …

Self-Balancing Robot

Introduction The inverted pendulum is an interesting case in the study of control systems because of its unstable nature. A pendulum is considered inverted when its center of mass is placed above its pivot point, meaning that its only equilibrium point is when its center of mass is directly above the pivot point. This is …
