hi
i want to make a digital guitar tuner. I've basically thought of a microphone to receive the audio from the acoustic guitar, a ADC(808 may be) to sample the signal from microphone, and AT89c51 timer to count and convert it to appropriate frequency and display the corresponding note like A,A#,C,D etc.But i am confused in some things, like the signal from microphone is AC, do i need do convert it to dc before sending the signal to ADC?+does the microphone output is according to the frequency of the input sound note?Also i think the input from guitar should only be taken for a short interval of time to prevent multiple reflections that increase the frequency of the sound.secondly, i searched on the forum and got some idea about converting the ADC output to corresponding frequency by delaying the timer by 1 sec.I am also not sure on the programming parts, and general connections. If you need more information please say. Well i've only thought these things, i may be wrong, please correct me in that case.Thanks

-peace

Well there is lot of other electronics involved too other than just sampling using ADC.

I found this project which explains the whole theory behind a guitar tuner. Just go through it once.

Correction... http://www.8051projects.net/lcd-interfacing/lcd-4-bit-programming.php That gave me headaches... Mismatched coding between the 4-bit and 8-bit sections.

bye for now

Ajay Bhargav | 16 Mar : 10:27

ok guys see you later after dinner maybe.. if i get time

or tomorrow

Ajay Bhargav | 16 Mar : 10:26

well thats not my site

http://www.8051projects.net/microcontroller-tutorials/

check tutorial section.

Kuya_Marc | 16 Mar : 10:25

http://www.8051projects.info/expC6.asp is made for 8051, not 89C2051. After changing the port assignments, nothing appears on the LCD.

Ajay Bhargav | 16 Mar : 10:22

well i can assure you working LCD with my tutorial

Kuya_Marc | 16 Mar : 10:21

I have a whole bunch of LCD tutorials bookmarked. None will work, as-is, so I have to reconfig them, but they still don' t work.

Ajay Bhargav | 16 Mar : 10:14

hmm well.. so in that case i would suggest you go through LCD tutorial and check what you're doing wrong.

The #1 reason why I have my own blog is because I can be very sarcastic at times... I just don't want to cause problems. Hopefully my MCU projects will get me offline and back in to reality.

Ajay, I write my posts, offline, with Windows Live Writer. The problem over here is, http postings fail due to a TinyProxy Cache error from my ISP. I've written huge http posts and lost it all after clicking the submit button.
