10/10

1 (LED): Good
2 (Nodding): Good
3 (Parallel): I sometimes got repeated noises when I pushed the button - it should play the next noise in the (reversed) sequence instead of repeating. This is minor, though (-.5)
4 (Fork/join): See above. I'm not going to dock you again for it, though, since it's the same problem.

9.5/10


hw2
Very nice segmentation - red and green thresholds give well-defined boundaries around objects with very little noise. Nicely done!

Part 2:
Counting: This only worked because you got lucky - you really need to de-noise the pink and blue blobs before you count them. Your code was actually counting every little pixel of pink or blue noise as an additional blob, and it just so happened that this worked out the same as if you had properly de-noised. -.5
Containment: Result sketch was blank. Looking at your code, it seems like you weren't looking for the right colors, but even then, your code wouldn't have worked because the boundary generally comes in pretty noisy, and you need to do something about that before filling it in. -1
Distance: Good
Freestyle: I would've appreciated a description of what you were trying to do, though the code made it fairly obvious. Unfortunately, none of the provided sketches actually contain any orange blobs, so your code didn't really do anything. I'll give you a break since I can see that your code would work with the correct color. -.5

Part 3:
Shell Game: The code you provided me didn't work because color names are defined in all lowercase. This is a minor problem, but it's something that actually running the program even once should've found. This might have been something that just changed in Tekkotsu, and if that's the case, I'll give you a point back. However, even when I ran it with the corrected color names, the arm pointing seemed strange - it bent the arm and never seemed to point to the center. -2
