My creation is a sphero SPRK+ and I made it go in a circle. I learned that when you uses a sphero SPRK+ you have to code them to do what you want. Some standards my project tied to are Empowered Leaner because I pick it but I ask a friend to help me some I did the coding right and so that it turned out the way I needed it to. Another standard I used was Innovative Designer because I had to uses edu to do my code and to connect to the sphero SPRK+. Some challenges I overcome was code my sphero SPRK+ and coming it connect to the sphero and when I was making it I had to figure out how to uses edu to code it and connect to it. Something I would do differently is the code because I would like it to go longer or do something different with it to come it look better. If you worked on buildings it could help you with how long you need the boards to be and how long the light needs to be from the ground.
