hi. I don't really know much about what i'm doing but want to try to make something. I've attached a picture to help you visualize it.
What it really needs to be is a buzzer system for a computer game im making. I want 5 buzzers (big push buttons with LEDs) on wires connecting to a central usb device, which connects/communicates to the computer. I want all the processing to be done by the game (pc's cpu) rather than the buzzer system. All the central device needs to do is pass button state info to the computer and light control info to the LEDs. I think of it as a gamepad without the pad (used by five teams rather than 1 person).
The problem: I don't know how to switch from bytes from the computer to signals in electronics (or vise versa).
So I have a couple questions:
(1) Do I even need a microcontroller for this or can a passive board somehow bridge the gap between computer and the buzzer leads, and
(2) assuming i do need the microcontroller, how many pins/wires of what kind does it need for all these buttons and lights?
again, the game is on the PC, this is just to be an interface device.
Thank You in advance for any time/consideration you give this.
EDIT: I don't actually want it to look like a gamepad :)
