Hi, there, I'm a beginner and I want to build a guitar tuner using 6 LED's oscilating at E-A-D-G-B AND E.
I'm thinking of a 4.5V logic circuit using a timer to generate the frequencies, and to have the LED's mounted in parallel with a filter to separate the frequencies for each string.
Can anyone help me with this?
