DIY Arduino Buttonbox

Hi @Lightman

I can't see you wiring, but I think you can use exactly the same pins as for Micro - 10, 16, 14, 8, 9 for matrix columns and 15, 18, 19,20, 21 for rows.
If any of columns or rows will not work - let me know Im sure we'll fix it

I have to the blue numbers held.

yes, use blue (digital) numbers

Hello I have got the board and now everything connected 25 buttons.

If I now want to compile the butten simpjoy_02c I get an error.

Can you help me

Do you install keypad library?

go to Sketch -> Include Library -> Manage Libraries



then type keypad in search and then choose "Keypad by Mark Stanley, Alexander Brevig" and then click Install

Ok thank you really so a simple mistake it now works Perfect all 25 buttons

Topmo you're the best I thank you.

hi mate im having alittle trouble the code wont verify it comes up error exit 1 cant comply to board any ideas im using the stardard script and a r3 uno

i think you need an Arduino Pro Micro because they are a bit different from Arduino Uno (different chip).

ok sweet im having the same issue with a dash im trying verify

Olá a todos, Estou tendo um problema, eu instalei o scatch no arduino pro micro board eo ultmio econder rotary não está desaparecendo. Aparente.

Hey all,

Im having sometroubles with this, i got a pro micro, installed the old joystick lib installed the keypad lib as specified,

How ever i cant get the buttons to work, the rotary's work like a charm, is there an older lib i should use for keypad ? or

Greetz, Eric

gday mate im going to buy the board today ill let you no how i going

im still tring to get the dash going

ive started and online course so im hoping to be able to help more guys out soon

im hoping to make some new products also like an anti roll bar box

I figured out that with the keypad it goes wrong, as soon as i use the analog ports it stops working, am using a 3,3v Pro Micro.

It seems that the A0 to A3 ( 19 / 21 ) ports will be un usuable for me, wich kinda doesnt makes sence, anyone got an idea ?

Hi all

sketch is adapted to V2 joystick library, also fixed issue with 4th encoder.
New sketch's version buttsimpjoy_02d.zip uploaded in the OP

Hi
I have use your sketch to make my Button box with 30 buttons and 4 rotaries encoders on a Leonardo.

There is my code.

Like you can see, I have add a row to obtain 30 joystick buttons and ended up using keyboard keys for the rotaries (4) due to the 32 maximum buttons on a joystick. It works very well but I would prefer to use only the joystick and no keyboard keys. I've tried to use a hat switch instead of the keyboard but I just can figure out how. Using two hat switches would allow me up to 16 buttons (each having 8 directions) or 8 rotaries encoders on a single joystick. It would be a good next version .
Any chance you can help me run this new version of your code?
Thanks a lot for all your work, without your sketch, I would still be learning to carry out my project, but with your sketch, I already have fun with my buttons box.

Hi Jocelyn

Check the latest sketch version 02d. In the initialization of joystick library you can define number of buttons. These lines:
//initialize an Joystick with 34 buttons;
Joystick_ Joystick(JOYSTICK_DEFAULT_REPORT_ID,
JOYSTICK_TYPE_JOYSTICK, 34, 0,
false, false, false, false, false, false,
false, false, false, false, false);

Change 34 to number of buttons you need. But please note that "game controller properties" can show only 32 buttons, so if you have more you should use some other app, for example this one http://www.planetpointy.co.uk/joystick-test-application/

I do the switch to the 02d sketch version, work perfectly.
Thanks a lot!
