I am looking for a way to output audio out of my Basys3 board. I only need to output monotones. The only sounds I will need to output will be the notes in the typical musical scales along with the octaves. My idea was to use the PMOD connector and use a simple 8-ohm speaker with the positive wire going to a random pin location and the other side to one of the common ground pins. Can anyone tell me if this is a viable method of achieving sound output? I have the code which was given to me by my professor but the code was meant for another board with an audio jack but I know I can do it without a built in audio jack. My main concern is the output impedance of the pmod connector which I don't know. I know I can design an amplifier but if I can avoid that, that would be great.
