Im building a simple sensor volyme control.
I want to run audio in and out though aurduino.
When my PIR sensor is activated the volyme should ramp up during 1,5 sec and than stay up for 300 sec. than ramp down. everytime the pir is retriggered the delaytime should be resteted.
Can Anyone recomend a audio in/out shiled that is suiteble for this project. its kind of a HIFI… pro sound setup so the soundquallety in importatant.
