This might be a bit of a dumb question, but what is considered the "safe" way to connecting a micro controller digital output to a Jamma button input.
Lets say I want to make an active autofire circuit (like the Reco), and I am usinga MCU running at +5vcc.
Should I just hook up the digital output pin directly to the button input, and have the digital out be high(+5v) when the button should not be pressed, and low (GND) to trigger the input?
No idea if this could have the potential to fry anything, but since I dont see any transistors or optocouplers on autofire boards, I guess it is fine?
