I'm working on a project which needs better audio quality than just a piezo buzzer, so I went out and bought a pair of used cheap speakers for $3. It turns out that they have RCA audio inputs rather than 3.5mm inputs. There is a separated left and right speaker, with a left and right RCA audio wire coming out of each.
I've looked around on the internet about connecting speakers to Arduino, but I've only found ways to connect 3.5mm/TRRS to Arduino, or the RCA video jack to Arduino, but not the RCA audio.
How should I go about wiring the RCA audio wires to my Arduino Uno so that I can play basic melodies off it? Are any amplifier circuits, voltage dividers, etc. needed?
I am okay with splicing the cables.
