Or you could use a graphic lcd (only slightly more expensive). Then, just convert the image on the PC to a bitmap and send over serial. The arduino can easily display this on the lcd.

You seem surprised that this requires code on the computer. How did you expect for the arduino to take a screenshot?

Cool idea! That expands the idea. If there is a animation on the area that is convertered to bitmap. How fast could I update the bitmap-2-LCD so it wont "lag" too much? Know what I mean?

Naah, I'm not suprised...

Oh! Okey... Don't know how to do that outside Arduino... Typical  smiley-fat

Maybe there's some app out there that already can do this?

Hello!

I have an idea that would be so awsome if it would be possible.

Please see attached image. What do I need to do to make that work?

I have actually done the same thing!

Check my first controller of two, here:

I will have two similiar of these on each side of a Kontrol X1!

I used the newest Arduino Mega 2560!

I'll be happy to answer any questions!

Oh. I think i should have explained better those two circuits controls the brigthness of the two led groups. smiley

Hi!

I try to hook up my controller to my Arduino Mega 2560, and then use it with JunXion to convert the serial data to MIDI.

1. Please see attached IMAGE to see me schematic. Should my two circuits on the bottom right work as a pull-down resistor for all my buttons?

2. Does Arduino have built in pull-downs/pull-ups that I can disable? How do I do that in the code if so?

I have also attached my Arduino JunXion code!

When I have it hooked up as this, the signals gets all flimmering and when I push ONE button, sometimes TWO buttons shows up as pushed and so on... Very wierd.

Thanks for your help!

Oh! I got a great reply from Support @ Steim! They are really nice and kind!

the lines containing the definition of the analog inputs look like this:

int input33[3] = {'a', 0, 16};    // analog input  {'a', x, 8} pin x is variable between 0 and 5
int input34[3] = {'a', 1, 16};
etc.

change into:

int input33[3] = {'a', 0, 10};    // analog input  {'a', x, 8} pin x is variable between 0 and 5
int input34[3] = {'a', 1, 10};
etc.

so, the number 16 has to be changed into 10. Right now junXIon assumes this is a 16-bit resoliution sensor while in reality it is a 10 bit number.

In junXion it will be shown to you in your 'user defined' data range, which by default is 0 - 127

Problem solved smiley

Thanks everyone for your time!

...the code is supposed to work with JunXion. And is made by the guys who make JunXion... www.steim.org! They are very good!

I'm not this kind of code junkie... Don't know what to do!  smiley-eek

The code is attached in the first post! I attach it here again!

Thanks for your help and time!  smiley

Wiho! It worked =) I got values from 0 to 1023 =)

Now I'm ready for the next step  smiley-eek-blue smiley-red

Hm... It does WORK I guess. But I only get those values... Don't know why...

But I have connected 1 & 3 on the pot to GND and 5V, and 2 to Analog PIN0.

And I have stated that I want to use A0 in the code as attached.

Everything seems fine(?)... But I get those low values...

I'm a noob. Sorry.

Hi!

I have my 10k slide potentiometer hooked up to my Arduino according to this guide:
http://www.arduino.cc/en/Tutorial/Potentiometer

And I am using attached code.

I am using JunXion to convert serial data to MIDI. And the only values I get from the analog input PIN0 is 0.00 to 1.98.

With this hooked up and everthing, I doesn't get the correct functionality in ex. Traktor Pro. The fader only move a liiiiiittle bit.

What have I missed?  smiley-red

Got any suggestion on what I have done wrong?
14  Using Arduino / General Electronics / Re: Serial input from button on: February 17, 2011, 04:54:42 pm
hm... I think I lied to you...

Correct fact:

When button is released: The LED is dimmed
When button is pushed: The LED gets brigther

BUT. When I connect it like this. JunXion doesn't get any signals...

BUT. When I remove the 5V from the other connection (not the 5v from pull down). It DOES get signals..

Don't know why though.

That code makes my Arduino work with JunXion... Don't know why it is so big. Doesn't the pin definitions begin at row 40?

I will hook you up with a picture in a minute!
