Topic: guitar frequencies (Read 2 times) previous topic - next topic



I installed the library "frequency Library" and it complied well,

thank you PoulS and other guys in thread :)



is there any help about this thread,http://arduino.cc/forum/index.php/topic,142209.msg1075998.html#msg1075998 , still I coun't figur out , calculating the frequency of guitar strings???? any hints ?


Are you trying to visualize the data or calculate the frequency?

You know that the string plucked will be the loudest part of the sound by far?
And that loudest sound is highest amplitude at the peaks?
So if you feed the signal through a resistor of high enough value to the grid of an NPN transistor, only the peaks will turn that on. Blip, blip, blip, count the blips per second and you have what?

I find it harder to express logic in English than in Code.
Sometimes an example says more than many times as many words.


Hi  GoForSmoke

I just want to visualize the string frequency(guitar string) on LCD.


You've got some code you haven't showed us.

You've using some hardware to get the vibration information that you haven't told us about,

My car still won't start. The seats are leather. Does that help?
