con-sistant
greating;


I have been working on my button-box build for the last two months and getting ready to release the video on youtube.

The build will consist of;

24 total inputs
3 flip cover toggle switches (power, ignition, and your choice input)
3 momentary on off on mini switch (2 inputs each)
10 varied momentary push buttons
1 engine start button
2 encoders (2 inputs each)
5 function feedback L.E.D's
4 permanent on L.E,D lights (i.e engine start)
2 port usb charger (optional)
Usb will be a detachable aviation plug
Pinyl wrap finish (optional)
And a holder for tablets or smartphones for (your telemetry apps)

NOTE; This build is compatible with any Console that allows you to plug in a keyboard.
and of course a PC


the button box is powered by an arduino pro micro (no keyboard hack)
2 part video.

Complete Step By Step instruction, No need to know anything about programing. All is provided for you.
Programs along with sketch.
all you need to do is purchase the parts necessary for the build.

Plus will be giving away small footprint 20 input button box. for more details visit my channel.
Subscribe to keep informed about video release

(button box build will not include shifter in picture)
This is a 34 input button box. (prototype)
Early rendition of the button box. ( we will be building a smaller version of this.

hey guy go check out part 4 of the build. in op.

these are just some pics of the actual button box finished
sorry about the fisheye veiw

with the lights on

two usb charging ports

DPDT toggle switch

safety cover switch
power unit
power usb
and ignition
GOPR2212.jpg

usb plugged to device
GOPR2211.jpg

usb powered, works independently from power unit. so you can have the box off and still charge your devices
GOPR2217.jpg

and finaly mounted on my rig

stay tuned for part 5
 
hey guys this is the arduino code for the DIY button box

those who are not familiar with arduino.

1) open arduino ide
2) click tools select your board and com
3) start new
4 delete all lines.
5) paste code
verify and upload

Code: 
/*arduino pro micro 24 input Button box with 2 encoders and 5 fuction led
porgramed to be compatible with all devices that have keyboard compatibility
this sketch was created/altered and designed
by Carlos Reyes
with help from the arduino community and libraries
on august 2016
for the purpose of DIY project on youtube channel
metadata is still in progress so search
2727clos, carlos reyes, clos2727, clos reyes, or game on
email clos2727@yahoo.com */
//version 1.00   encoders confirmed and working
//version 1.50,  added buttons to sequential shifter
//version 2.00   removed shifter added keyboard press
//version 2.50   added 5 led lights
//version 3.00   debugging buttons and led function
//version 3.50   button presses are synced with led lights (final)

// button box version   V3.50
//

/* note
 *  if using leonardo be sure to change pin numbers as pin numbers on pro micro differ.

Hi, I am looking to build my 2nd button box, my fist button box I used an old USB keyboard’s circuit board and soldered onto the tracks. I’m looking to make one using a Teensy or Pro Micro.

When using the Pro Micro I keep getting errors on the script when I “Verify” the copy and paste script onto the Arduino IDE Application. But when I “Veryfy” the script from the Applications examples etc they comeback fine, no errors! Any help is much appreciated. I’m only looking to do a basic button box for Project Cars, to assign buttons in the game for stuff like car assists, wipers, lights etc... thanks
