| - | Never understand why a piano has so many keys? Think a single octave is more than enough? The FPGA piano allows you to practice your favorite scales or chords and even lets you listen to some of your favorite tunes while you take a break. Our piano has two different modes Piano Mode and Song mode. In Piano Mode, the user can toggle the switches to play different tones and chords from the eight notes in an octave. In Song Mode, the user can depress the buttons on the FPGA to play four different recorded sequences: scales, a simple repeating pattern, Happy Birthday, and (FPGA)Piano Man. | + | Never understood why a piano has so many keys?

| We undertook this project because it offers a synthesis of digital logic synthesized on an FPGA and the world of analog signals that show up in other classes. Additionally, the piano provides a fun opportunity to explore musical interactions with the FPGA and translate between the frequencies of electronics and the frequencies of hearing. Lastly, we spent a lot of time this semester modulating clock frequencies and coordinating timing, so we wanted a final project that allowed us to demonstrate our understanding of these concepts. | We undertook this project because it offers a synthesis of digital logic synthesized on an FPGA and the world of analog signals that show up in other classes.

| Because of volatile finals schedules we were unable to follow our original work plan but still managed to meet often and accomplish each task within a reasonable time frame. It was fortunate that we had scoped our green feature set to be relatively easy to quickly implement. This allowed us to be flexible about which of our yellow features we implemented.We chose to pursue switching octaves and playing chords because we were excited about the prospect of being able to play a wider variety of songs. This flexible work plan structure with green, yellow, and red features allowed us to get something simple working quickly and then have fun extending the project. | Because of volatile finals schedules we were unable to follow our original work plan but still managed to meet often and accomplish each task within a reasonable time frame.
