Aside from the problems with the guitar, troubleshooting the electrical and C program errors also proved to be a hassle. From the very early stages of development, this project was riddled with both. Some of these included floating inputs, current amplification, switching problems, and finding correct 7-Segment pin outs. All were solved in a timely fashion.

There are many things that could’ve been done differently with the project. The most apparent change that would be made would be researching wood densities for guitar necks to see which can best withstand being drilled into. Along with that, better implementation research for smaller LEDs could benefit the drilling process by using smaller drill bits. Another change that would be made would be cleaning up the hardwired fret board of LEDs to a Proto board custom designed for the length of the guitar neck. This would eliminate the messy hardwire circuitry that is currently occupying too much fret board space. A battery pack circuit for the AVR would also have to be implemented to make the design portable if it was ever marketed as an instrument.

In addition to these more important changes listed, slight design improvements include additional switching, different color LEDs, and different programs. In the original design, the guitar illuminates the LEDs and could be played while illuminated. A switch could be used to power on or off the AVR to be played either as a normal guitar without the aid of note-lit LEDs or with them. The different color LEDs would each indicate a different note, containing 12 different colors of LEDs on the fret board. This would help better acquaint the user with the different notes in a scale. Lastly, the best part of this design is that its wiring is universal. This leaves a very broad range of different programs to be created and that can be downloaded to the board directly without any additional wiring or soldering. Some of these might include additional musical scales, chord mapping, and interval mapping.
