(Here you describe the key issues and problems with the projects, as well as the criteria for the success of the project).
(These issues would be all the problems you encountered and how you resolved them).
You are not expected to have everything working perfectly first off.
(In fact for the HSC the more problems you have and resolve, the higher the marks received, as the student/s were more challenged and had to work out solutions).
Scratch
Where you made some code errors and the Scratch did not work, as it should have. There could have been problems with the computer graphics card, which changed the way the Scratch behaved.
Sphero
Were you able to download the Sphero Ap on your mobile device?
If not why.
Did you have any issues with controlling the Sphero, using the exercises given.
