*Buildlog* Midi foot controller from gamepad!

[rudeez]

Damn.. That sucks, i should have read more about htis stuff before i got it going. Im always like that, i want it to happen right now, not later.

Anyway, i could probably change the electronics later on.
For a normal LED blink when the button is pressed, how should it be wired you guys think since it's 9 poles on the switch.

not sure about your buttons but this is how fbonito wired up the arcade buttons for his gamepad based awesome diy arcade controller:



i really have no clue why there's 9 poles on your buttons...

Will try that LED scheme when i get the switches combined with another i found on the net.
I fixed the box now atleast and made it black, not by spraypaint but by wrapping it in vinyl, i work at a signshop and is used to doin cardecor and shit so.
And most important, it was free

I think that vinyl's gonna be fucked when you start drilling holes in the box. Lucky it's free I suppose?

good point... probably better to drill the holes first...

Haha, jeah i know but i gonna make a "brushed aluminium" look decal just a bit smaller with rounded corners on top of it and print the name of it aswell as namnes above the buttons and knobs. gonna carv the vinyl away before i drill the holes so that's fine, i just wanted to do something in the meantime while waiting on the buttons!

EDIT: Is it possible to do dimmer leds to the 10k pots?

Yes, connect the variable connection (often known as the wiper) to the positive leg of the led, and connect the negative leg of the led to ground. This should light up the led when at full, keep it dim at around half and off when in the off position.

For the foot pedal/pots, you could use something like this...

And just wire up one of your analog inputs from the gamepad to a TRS jack on the side of your box.
The pedal is just a pot on the inside, so if it's the wrong resistance you could just open it up and change the pot.

And to setup the LEDs to stay on when you press a button on your pedal, you could wire up a relay like one of these...

to each button and each LED.
The relays would act as on off switches.
You might have to power the led's with a battery rather than the board though.

So, im currently working on the knobs while waiting for the switches to arrive.
I've hooked up 10k linear pots to both X and Y axis.
They're working great and except one thing.
It dosen't react until iv'e turned it to about 11 o clock.
And the other one reaches maximum at about 2 o clock.
Does that have to do with calibrating the gamepad or is it wrong ohms on the pots?

Also, how and where do i hook up a led to them to get them to act as dimmers?

EDIT: I noticed something about Arduino UNO, would that work for my project and all the things i wanna be able to do with leds etc?
