I did buy a board from this site, which basically allow me to connect buttons, switch and other controls with ease and no need to program anything: http://derekspearedesigns.com/dsd-36-button-controller-avx.html
Now, I did order some buttons and realized that they are made for some sort of connector; I tried to solder wire on the contacts but the wire breaks at the junction, as soon as you move the connection a bit. This is how the buttons looks like:
Is there a connector that slot into these connections; and is solid enough to not come off? I did look at sites that sell arcade accessories, and the only thing they sell is daisy chained wires; which is not what I need, because the board I own, require 2 connections for each button. I could cut and modify the chained wire but I want to see if I can get the correct connectors first.
The second issue is related to how to power the button LED; since they support 12V. I did buy a 12V step up that works fine with the square buttons, which takes the 5V from USB and output 12V for the LED; since the switch connections are separated from the LED connection.
But I also use this type, which has just 3 poles instead of 4; and my concern is that the board seems to be 5V tollerant, so if I add the 12V coming in from the step up device; I may fry the board?
