 		 #124745 - Auto Violin Tuner
Dear Friends,


Nowadays i'm trying to play violin. The first problem is tuning of violin strings to G,D,A,E notes. How can our friend micro can help me? I thought to convert sinewaves from violin to square waves and then compare it with right freqency and lit a LED when matches with desired freq. Input may have following schemes


1. Acoustic Coupling of violin sound using a micro phone.

2. Magnetic pickup(no scilence required).

3. optical Interruptor coupling(same benefit);

what you suggest. any ideas.
