| Wiring a keyboard hack? |
| (1/1) |
| RecycledPast:
For my first project I used an IPAC but I'd like to replace it with something cheaper since the control panel is only 1 player with a total of 5 buttons (p1 start , p2 start , coin, p1b1, p1b2) I've torn apart the keyboard, mapped the matrix, and soldered an IDE cable to it. I assume I won't have to worry about ghosting since it's such a simple cp. I'm wondering how to actually wire it up to the buttons. For example, how do I connect up the player one start button which is the key 1. Do I connect the two wires that make up the key 1! to NO on the push button? But what about a ground? Or do I connect one of the wires to the NO and the other to the common contact? |

Since you have mapped the matrix you are almost done. Connect one of the pins that makes "p1 start" to the NO tab of a microswitch. Now connect the other pin that makes "p1 start" to the COM tab on the microswitch. Do this for each button. |
