Marvel Sorter

We were put to the challenge to create a system that would sort into different categories marbles of different colors and materials we could choose 3 out of the 5 but we decided to do 4. We chose the 3 crystal ones (transparent green and red) and the metal one. The reason behind this decision was that we could use the photo resistor to measure the amount of light that goes through to differentiate between them.

Unfortunately due to different reasons we had to abandon the project so it never worked we had planed to use pneumatic to operate a gate to let marbles in one at the time and we had built two motors to compress air into a container to be used.
