AY-3-8910 Sound Generator (Arduino Nano Controlled) PCB only The AY-3-8910 sound generator has an 8 bit address/data bus, allowing access to 16 internal registers. Using Arduino Nano and a library, the registers can be controlled to generate 3 channels of audio tones or noises. Their amplitude (volume) can be set, either by setting a fixed volume or by turning on an envelope feature to make the volume fade in/out etc. YM format chiptune files can also be played, either from program memory or an SD card.
