Day 4

Today we experimented a great deal with the score keeper/candy dispenser. We began writing the program for it, and figured out how to use reflectance sensors to cause the candy to move forward a certain amount each time a target is hit. Three hits will bring candy to the successful contestant.

We also devoted much time to reinforcing the board. Here's a picture of the wall with cardboard covering the back:

We inserted the switches as in the following photo. The structure we devised is very sturdy and can withstand forceful impact without breaking. This switch mechanism is one of the most important parts to keep intact:

We had to make the targets smaller as well, since the larger ones would get stuck when it caught on the top edge of the board.

Still to do:

1. Build signs for the cars
2. Build colorful targets
3. Build bubble machine
4. Write working programs
