The final project was a working Skittles Sorter, that once fed a bag of skittles would wort the color and place the correct skittles into the designated cup. If project is completed properly it should sort the skittles correctly. At that point, it is alright to pour a bag of skittles into the designated collection point. Once centered plug in the Arduino and after a short delay the rotary feeder will begin to spin. To start the project completed, the feeding board in the rotary feeder must be set to a known location so that the skittles will stop on-top of the color sensor and get a correct reading. Once the sorter is completed and works you may complete the following project with the following step.Begin to progressively adding more parts to the sorter such as the color feeder.Once the machine is completed, testing on the skittles is necessary to normalize the environment and the colors the color sensor is receiving.Once all preliminary steps are completed within procedure you may begin the construction of the machine.In order to do that we had to get readings from a certain number of skittles and then take the average of the red, blue, and yellow values that the sensor gave us. Another aspect of the code that we had to change was the calibration of the colors. For the servo, the code moved the servo so that the skittle would drop into the appropriate tube. For the stepper, we had to add code that makes the color sensor sense when a skittle is over the sensor. But we had to add code for the servo and the stepper. Get the feeding mechanism to work in unison with the rotation of the rotary feeder to feed the correct skittles to the right input slot.Ĭ.Ĝontinually check and renormalize the colors for skittles as they will change with multiple iterations of machine change.įor the software, most of the code was given to us. Get readings from the color sensor, and normalize the color of the skittles for your specific environment, change the averages in the given code.ī. Alter given code to begin the process to sort skittles.Ī.ğind rotation difference for rotary feeder to find the correct spot where the skittle can be read in from the color sensor.Get skittles to run through the machine and fall into a designated place, no need to sort skittles at this point is necessary. Iteratively design and create different parts for machine.Ī.Begin design and components for overall structure and completion of entire machine.ī.Ĝolor sensing, our case part of rotary feeder.Ĭ.ĝistributing, our funnel cup to curved distribution piece.ĭ.Ĝollection, tubes from our distribution piece to our cups. once plugged in, or immediately after pressing a start" button), and should work without human intervention. Your machine should be able to work immediately (i.e. The machine must be able to sort a standard (vending machine sized) bag of skittles in under 3 minutes. Design and develop your own machine (built using laser cut and/or 3D printed materials) that sorts a standard bag of skittles into 5 different bins by color (purple, yellow, green, orange, red, blue).
