| Notes about using the FPGA guitar. When on manual mode, use switches 7 through 1 to select your note. Only one of these switches can be on, otherwise the guitar will not play a note. Then, “strum” on switch 0 to change the note. Operation should move like: choose note, strum, repeat. To switch to and from “Sweet Child O’ Mine” mode, press button 0. | Notes about using the FPGA guitar. When on manual mode, use switches 7 through 1 to select your note.

| Our work flowed well. Our simplest iteration, which was just a strummable sound maker, was achievable. Luckily, we worked quickly enough that we were able to achieve one of our reach deliverables, which was an automated playing mode. This consisted of allowing users to press a button so that the FPGA would play a preset song. | Our work flowed well. Our simplest iteration, which was just a strummable sound maker, was achievable.
