Final Project: Works-Like Model

We had to prepare a works-like model (a model that does not necessarily look like the final model but has similar/same functions).

We experimented more and worked on the photocells so that they would detect black dots and then play a sound. The most challenging part was calibrating each of the eight photocells to make sure that they did not trigger the sound when the photocells detected white (and trigger the sound when they detected black).

We drew the first 7 or 8 notes of "Ode to Joy," and our music reader was not perfect but was able to read several of the notes.

Next time, we need to work on the scroll moving mechanism to make sure the scroll moves straight.

Our program on PICO Blocks after we calibrated each photocell.

 Our program on PICO Blocks to test for sensors (photocells), sounds, and LED light (color).

We drew a thick black band to make sure when the sensor mechanism was over the strip, all of the notes played (one by one).

We tried to test and draw the notes in "Guitar Hero" style, but this did not work too well. 

 Our works-like model. It has a lot of flaws, but we will continue working on it.
