hye guys.i just want to ask about making new projects.is it possible to make a guitar tuner using only arduino duemilanove atmega 328 and few LEDs?if so,how the code look like?sorry im a newbie to arduino.can someone point me to the right direction??thanks btw.
i forgot to ask.how arduino reads the frequency from the guitar in the code?i just cant understand.pls help
This site looks like it has what you need:
Tony Chai.
hi,
Why don't you use a CI that convert the frequency to a tension? then this tension is compared by the arduino board with differents tensions corresponding to a note...
for exeample:
If you don't understand my idea to do it...tell me i will do a schematic.
Have fun
Can you use a microphone (or jack) and read the signal -- and detect the frequency? Yes.
There are examples on this site and in the various Arduino books.
Try the Evil Genius Series and the Arduino Cookbook -- both mentioned many times here.
Could I do this? Yes -- in a day or two of time to find the parts and and write the code -- mostly by grabbing stuff already done...
Use the Search function and try different wordings -- frequency, tune, count etc. You will find code...
Hey there!
I built something like this around xmas 2008. I wrote a small blurb about it here:
Hope this helps!
This one!?
