Skittles Sorter: Overview

Skittle Sorter

Our final project is a Skittles Sorting Machine. The machine uses a RGB color sensor, a RGB LED, three servos, an Arduino, and the A3BU AVR microprocessor controller. This machine was constructed with K’Nex, cardboard, electrical tape, duct tape, scotch tape, super glue, a nike shoe box, modeling clay, and rubber bands. We also ordered some 3-D printed parts. Most of our electrical parts came from the lab group’s personal inventory, however a few parts were ordered through school using Quartzy.  The Arduino IDE 1.6.8 was used to program the Arduino and Atmel Studio was used to program the A3BU. Eagle CAD was used to draw the electrical schematic.
First, we assembled the structure to hold the servos, Arduino, breadboard, A3BU, and tubes used to move the skittles through the automation process. Next, all the electrical parts were connected and the Arduino was programmed to control the servos and sensor. Finally, the process was tested and RGB values were obtained for various colors so we could program the sorting servo to swing into the correct position.
The project was successful because we used ideas and principles learned in class to construct an automated sorting machine. The machine was able to take in a bag of unsorted skittles, put them through the system, and come out the other end sorted into correct piles.
