Hey in want to thank you fro this video, and my question is, after watching your video i started researching whats Arduino etc. but now there different one and even old ones on ebay, my question is which one would work for me, i simply want to convert the analog input using a expression pedal and release midi message to my Whammy pedal, by the way do you that i could also be able to change the different selections of the whammy using arduino, have presets and conbine presets on it? lol
@mikyj139 - Thanks for your comments! yeah there are a lot of different Arduino boards about.. its an open standard so anyone can make and sell them and also they are based on different chips (Atmega168, 328 etc) but any one of them will be suitable I think. For MIDI stuff you can use a cheap 168 based board. The code I used was based on code by Tom Scarff, so I did not post it since much of it was borrowed. However take a look tomscarff .110mb .com look for switch and controller pedals project
Really cool toy you made, do you have the schematics for this? it would be great, i want to use an expression pedal to control the whammy pedal , is that i dont find the whammy pedal sturdy, do you think it would work? manily i want to convert the expression pedal input and out put it as a midi, thats all im interested, i would greatly appreciate your help
hmm - I *think* an sustain pedal is an on/off switch but an expression pedal is a variable resistor... so I think you need an expression pedal not sustain
Nice! I have an idea to build a full midi foot controller, but I am quite new to electronics. Would this Arduino Duemilanove 328 be sufficient to have two-three-four buttons and two expression pedals? If I get it right all i need is too hook up the buttons and pedals to analog inputs on the board and midi connector to analog outs, and the rest is just programming the board amirite? I think it would also be possible to use usb instead of analog midi out, right? Would be cool to see instructions.
your Arduino will do the job fine and your assumptions are correct. A couple of resistors are needed and thats about it. I got started with all this stuff using Tom Scarff's miduino boards and projects (google it, youtube wont let me post the link) check the midi pedals project. the code is standard Arduino stuff and should work with any Arduino board. If you only want to send MIDI (not receive it) then you need very little extra electronics. Good luck
As you have a ready made arduino board, I think you'll just need to connect your TX pin (usually arduino digital pin 1) through a 220 ohm resistor to pin 5 of your midi socket and mdi socket pin 4 to your 5V output via 220 ohm resistor. look at some of the project source code files from the miduino site. BTW my board contains a voltage regulator (black thing) so I can run it off a 9V battery (converts 9V to 5V) plus a crystal etc. Your arduino board should already have that stuff taken care of
EOWAVE make a USB expression pedal which I think shows up as a MIDI input port.. they also make a box to do the same with 4 pedals but they're quite pricey... if its the electronics that puts you off DIY you can use a standard Arduino microcontroller board (cheap on ebay). I also plan to post some instructions when I get a moment. Cheers

@mikyj139 BTW if you want to do clever stuff with stored presets, multiple controllers etc I'm sure you can with an Arduino!

a sustain pedal is enough or an expression pedal is something more?
sorry for the question :D

i had not know the difference between expression and sustain pedal (wikipedia is not so clear in this case ;) )
thanks!!

Cool. Thanks for quick reply.
And just to clarify it for myself, I don't need any extra boards to get midi output, do I?
Btw, is it a transistor on your board (the black three-legged thing)? What is it for?
Sorry for noob questions :)

gr8 project!
I have the same soundcard and the same problem (controlling the wah)
If I suck at DIY do you have any alternatives?

@hotchk155 Is ther any way to have the source code??? I have the same pedal and chip (arduino chip) but I can't work it out.

I sent you a PM with the code. On this project I was using a modified version of Tom Scarff's Miduino code for pots to cc# project. Google on Miduino

How's the response? Do you notice any lag at all?
alphabeets 2 years ago
No, the response is fine.. at least as good as the mod wheel on my controller keyboard.. no noticeable lag at all
