Im currently making an Arduino Synth keyboard for my microcontroller class. Im stuck on the equalizer part and effects. I dont want something very expensive so im trying to put the effects on my arduino mega. Still I have the pieces to do the equalizer in the output of the arduino doing the following chart:
Buttons (Keyboard) ----> Arduino Mega (Waveform Generator)--------> Preamp (Gain, Tube effect, Volume)----> Equalizer------> Amplified Speakers
I Wanted to make an passive EQ but failed in all my experiments so I was looking in the internet and found this active EQ diagram that is inexpensive and looks nice. So I bought the IC by Ebay. I Have diferents Caps and Resistors but not exactly the same as the diagram. How I can do a conversion there?
Caps that I have:
1 x MK754U40 0.75 uf 400V 50/60 Hz
1 x 1000 uf 25V electrolitic
8 x 0.047 mkΦ (I think that is 0.047 uf) Mother Russia caps Paper In Oil K42Y-2
1 x 1000 uf 35 v electrolitic
2 x Sprague .47 uf Orange Drop 200DC
1 x 1000pf 300VAC
2 x 47 uf 35 v electrolitic
1 x 470 uf 25v electrolitic
1 x 47 uf 10V electrolitic
1 x 47 uf 16V electrolitic
Pots that I have:
2 x B10K
1 x 5K
1 x B1K
1 x B500K
10 x A250k
Resistors that I have
Like 20 resistors of 220 ohms
7 x 20kohms
10 x 10kohms
5 x 1kohms
8 x 5 Mohms
8 x 57 kohms
Any help will be appreciated
