**The parts that say, "Written by Diana" is written by Diana, everything else is written by Jessie. Diana wrote a lot of it because we worked as a group and her job was to make the portfolio.
Description: This project consists of using servo motors to power a microbit and designing and printing a skittle dispenser. The microbit will push the part holding the skittles to the side, causing the skittles to fall and, dispense. We will use the microbit programmer to make it spin and dislodge the skittles. It has a bounding box 7 x 7 x 5 inches.
Brainstorming: We used Mrs. Tran's example as a guide to our prototype. We used 3D printing, acrylic, and the microbit. We used the microbit python website to help with our code.

Below is a photo of a sketch of the prototype.
Procedure: After brainstorming and sketching the prototype, we started designing on TinkerCAD the tray, dispenser, spinner, and holder. Then we printed the designed components, and assembled the Skittle Dispenser. All components fit other than the skittle holder, which was not deep enough to hold the spinner on the servo. We remeasured and reprinted. We programmed the Microbit and tested the Dispenser. Below are photos of the components and the final product.

Below are pictures of the tinkercad prototypes next to the 3-D printed versions.
This prototype printed quite well. There was no problems with this.

As you can see, there was some trial and error with this spinner. The first time we printed the spinners, they didn't fit the dispenser. So, we reprinted and the spinner fit the dispenser but the servo motor's blade didn't fit the spinner so we just laser cutted a piece of wood that the blade fitted into. The holder was near perfect, we just reprinted it so the color stayed the same as the spinner.
<-- This is the final project up and running!
This is the code for our microbit. There was a lot of trial and error in the code too.
Reflection
S: I think the strengths of our team was that we saved alot of time by not having to reprint anything too many times unlike some of the other teams. In the end, our team just laser cut a piece of a wood and glueing it over the plastic.
O: A missed oportunity is that we didn't connect the holder to the dispenser which caused some problems.
U: I now understand how to print on a Bambu printer, which I didn't know how to before.
L: A limitation was how we didn't really have enough time to perfect our skittle dispenser.
WISCR: I think we did really well on the letter "I" which is "insightful and critical thinker" because we had to be critical thinkers when we though of how to over come the errors in our project. We also did really well on the letter "R" which is "respectful individuals of character" because we were really respectful towards each other and worked well together.
