Midterm Project Progress

For the midterm, we decided to build a simple slot machine using LED matrices, MAX7219 to be specific. There will be three reels of LED matrices and a total of ten scrolling images.


The user will be paid off with candies contrasting to traditional coin payouts. This is where the Halloween theme emerges in our project.


Each image for the reel should be translated into the code, like one of the examples shown below.

B("00000000"),

B("01100110"),

B("11111111"),

B("11111111"),

B("01111110"),

B("00111100"),

B("00011000"),

B("00000000")








We designed a simulation using openFrameworks as the video shown below. We also started designing a lever to be pulled to enable rotation of the reels.
