Chord Hero


     The Chord Hero group project designed and built a device for teaching guitar chords without prior knowledge of guitar playing.  The device consists of a series of LED's and push-button switches that displays a chord and allows a user to input the correct response.  An Altera DE2 Field Programmable Gate Array(FPGA) is used in processing input and output of the Chord Hero.  The chord selection and output to the LED's are sent and then the user inputs the correct button sequence to learn the chord.  When a correct chord structure is inputed by the user, via the switches, the FPGA will display "Good".  The following Wiki is a brief overview of the project and final prototype. For a detailed report you can view the final professional report available to for download at the following location.Chord Hero.pdf
