DDR

I was previously building and selling control boxes for Cobalt Flux DDR pads. I was only building and selling them because I made one for myself, and had a few people reach out for them, so I hosted this page. About a year after I started making my boxes, Cobalt Flux started producing pads and boxes again, so I stopped. Because of that, I am no longer officially offering control boxes for sale, except for custom/strange pads that need different pinouts.

Because of this, I am releasing here a set of instructions and code that anyone should be able to use in order to build their own DDR Pad Control Box.

Parts List:

Arduino Pro Micro(Amazon (3 for $16)

VGA connector(Amazon ($12)

A box((Here is the 3d model for this design)

Below is the arduino code you will need.

Simply attach pin 1 of the VGA connector to any ground pin on the arduino, (skip arduino pin 0 because the code does), and connect pins 2-5 on the VGA connector to pins 1-4 on the Arduino.

Assembly:

Put it in a box.

If you 3d print the box above, after you test the box, just use hot glue to stick the VGA connector down, then use more hot glue to stick the arduino on top of that, and again more hot glue to close the box. super simple to assemble and you can take it apart with a hair dryer if you need to! (just be careful, melted plastic is dangerous)

/*

* This code contains the follow functions:

* - void setup(): Sets pins 1, 2, 3, 4, 5, 6, 7, 8, 9 to input with pull-up resistors enabled and begins Keyboard functionality

* - void loop(): Main loop - reads pin voltages and sends out corresponding keystrokes via USB

*/

/*

* Pinout:

* - "HIGH" voltage button contacts - pins 1, 2, 3, 4, 5, 6, 7, 8, 9

* - "GND" voltage button contacts - GND pin
