The BIG Arduino MIDI controller thread

[MiL0]

This is quite handy:

Basically you buy an Arduino and one of these: http://www.sparkfun.com/products/9056 ($4.95) and you instantly get 16 analogue pots. The good thing about this mux pcb is that its really cheap and you can use multiple mux's... 64 pots should be feasible, if you're using an Arduino Mega, for less than £50 in total (if you buy an Arduino Mega clone for £20 like I did!)

I am using a arduino mega and making a custom MIDI fighter as a prototype for my own all in one controller Just doing it as an exercise to see whether I can do it.

I am making a controller featuring full LED feedback on 16 fully lit arcade buttons, 4 LED encoder and 2 super FX faders.

Should have it finished in time for late April

Hey Guys,

i´ve just orderd my arduino mega clone... I would like to connect it to my DIY 4 Deck Transport/Loop Controller for Traktor i´ve build with the pcb of an gamepad and an usb Keyboard. It Contains 4 Pots and 41 switches (16 Arcade Buttons and 25 smaller Buttons). That dosen´t worked that well (response, seamless pressed buttons, "jumping" values of the pots, no LED feedback..) and now i would like to try it in a better way

because of the fact, that i am absolutly not into programming im a bit scared about my "new" Idea.

Is it posible to connect the pots, buttons and as mutch leds as posible directly to the arduiono without multiplexers? And my other question: Do you think i could write the Code myself or is it too hard for a total noob?

Thanks for some replys!

45 pins would be required for your setup, so the mega should work okay without using multiplexers.

As for coding it yourself... Do you know C++? Have you programmed before?

[manou]

no... absolutely not Maybe a friend of mine could help me... I think i´m going to try it with this Tutorial

If i am using 45 Pins for my Controller, could i use the other 9 Pins for LED´s? or is there an easy way to connect more LED´s?

[DjNecro]

That tutorial is for creating libraries for use in the arduino environment.. NOT how to create a program for the arduino... A better tutorial would be: http://www.ladyada.net/learn/arduino/

As for leds, yep, you can use the remaining pins for leds... In order to get more you would use shift registers (such as a 74hc595).

Im gonna use an arduino for my project...i hope i can understand the code tho! what is the coding actually used to tell the arduino?

[DjNecro]

You program the arduino in C/C++

[BennyJ]

Yeah but why do u need to program it

[DjNecro]

How else is it going to do what you want it to do?
