PT2258 Volume Controller
PT2258 Volume Controler
This circuit controls the volume of up to 6 channels from 0dB to -79dB.
Connect this through I2C to a microcontroller, like an Arduino to control the volume. Sample code for Arduino below using this lib: https://github.com/sunrutcon/PT2258
#include <PT2258.h>
PT2258 volume;
void setup() {
volume.init();
volume.setMute(0);
}
void loop() {
for (uint8_t i = 1; i < 80; i++) {
volume.setMasterVolume(i);
delay(100);
}
}
