Hey there all, I'm going nuts trying to figure this out.
So I built my cabinet back in 2006, I used an IPAC with PS interface (not usb). I have 2 atari volcano buttons and I wired them to the 5v on the IPAC and when I played a game like Centipede, the volcano button's led would blink to say click me to start a 1 or 2 player game.
I think MAME was upgraded somewhere along the way to remove this feature and put it into a new app.
Well I'm changing my setup to use a Raspberry Pi and I just put in a new IPAC2 with USB. I'm not seeing the 5v pins anymore. What do I need to get this to work?

From your other thread:
I have some volcano buttons and I want to have the LEDs light up for player 1 and player 2.
Which of these describes what you want to do?
1. LEDs always on.
2. LEDs on when pressed.
3. LEDs flash when a coin is inserted, like the original Atari games did. (3:40 in this video)

If you want always on, take 5v from the spinner/trackball pins on your 2015 or newer IPac.
If you want flashing, you'll need either a pre-2015 IPac (still has the LED pins) or an LED controller board + LEDBlinky.
There's a firmware for 32u2 AVR boards if you want to roll-your-own.
- You might be able to recompile the firmware to run on a 32u4 board like the Arduino Pro Micro. :dunno
- There is a 32u4 firmware available -- "LWCloneU2__rev190.zip" in reply #11 (http://forum.arcadecontrols.com/index.php/topic,132903.msg1397118.html#msg1397118) of the thread below.
-- Looked at the schematic and it should work on a Pro Micro for your application. ;D
-- Ports D5 and D6 aren't available on the Pro Micro, but you only need ports D0 and D1 for the two volcano LEDs.
-- The Arduino should be able to drive the LEDs directly since they only draw about 20mA each. (no transistors)
