sorry for my english
I have a question
I have a buzzer that emits many different sounds and, also, 3 error codes:
1┬░) Bip Bip Bip at 440Hz
2┬░) Biiip Biiip Biip at 700Hz
3┬░) Biiiip Biiip Biiiip at 1150Hz
I want to decode these 3 error codes.
I can't touch nothing (the buzzer, the amp) than I must use a little mic
to capture the sound/code.
Besides, the buzzer is situated in a crowded place with people that speaks, screams etc.
Is it possible to do?
Thanks a lot and sorry, another time, for my english
