Overview
This device was designed to assist my client, who has Usher Syndrome, in playing the guitar without relying on printed music. Because the client has low vision, we created a system that audibly announces each chord to be played. An Arduino paired with a DF‑Player, speaker, and breadboard controls tempo, volume, and play/pause via high‑contrast buttons of distinct shapes. To suit the client’s preferences, the prototype runs from USB power rather than a rechargeable battery. The model includes a HC-05 transceiver module allowing for bluetooth connectivity. Fully functional and user‑friendly, the device enables the client to play guitar independently while prioritizing accessibility. It placed in the top 12 of 250 projects qualifying for the McMaster First‑Year Engineering Showcase.
