Multiple LEDs?

[ginkgoblue]

Quick question. Can you wire two LEDs on one output of pac64 or ultimate I/O?

Example, Inwant my coin buttons and joystick ball too leds to match colors (depending on game)....

So can I just wire them together on the same output or no?

I would advise against doing so with Ultimarc's LED controllers...

Why would you do that? How many buttons are you planning to light up anyway?

I plan to light....

4 player start buttons
4 joysticks
6 buttons for P1
6 buttons for P2
4 buttons for P3
4 buttons for P4
2 pinball buttons
4 coin in buttons

34 total buttons (2 too many for Ultimate I/O)

And I plan to let the only the joystick that is in use per game and only the matching coin in (on a coin door) with exact matching color at all times; which is why I am asking if I can wire the coin ins with the joys.....

Meh... Ditch the LEDs on the pinball buttons. There's the 2 you're looking for.

It says constant current drivers... what about more than one LED in series?

Otherwise I can recommend buying a couple of ULN2803 driver chips if you want to add more LED's to each output. They are cheap, easy to connect and doesn't require any additional components. I have used these a lot when for different LED projects based on Arduinos (that also has a current output limitation).

But, if I I use a Nepthring (or build my own, ala Chance's Flynn) I'll need more than one set of LEDs per stick?

I'd like to learn more about this. Any threads out there that describe it? Or any other place I can learn? I took a few electronics classes way back in college, but to be fair a lot of those memory banks have been taken over by something else, or buried at the least.

Buy another controller.

That's what I will end up doing I'm sure, but having ZERO experience with "controlling the controllers" I'm trying to wrap my head around the software side of it. Will LEDblinky or the like "see" multiple controllers?

Is there a good tutorial on this that I can be steered to so that I can attempt to understand this functionality?

For what it's worth..I have wired 2 RGB leds in parallel up to one output on the UIO to light my joysitcks (Followed Chance's method but applied to the UIO).  IE pin 1-3 have 2 RGB leds. The + is shared between each LED. Pin1 provides ground for the reds, pin2 the greens, and pin3 the blues.

While testing of current draw for the LEDS I used (the 5V tropical ones from paradisearcadeshop.com) at 100% voltage the current draw didnt' even come close to what the chip is rated. A single output pin on the chip (Y59116) supports 120mA per output per spec sheet http://www.ti.com/lit/ds/symlink/tlc59116.pdf

@5V non PWM the Paradisearcadeshop https://paradisearcadeshop.com/button-leds/92-tropical-mood-light-rgb-5vdc-led.html Run this when wired in paralell
2 Reds: 20mA
2 Blues: 20mA
2 Greens: 20mA

I run 3 LED controllers, from 2 different manufacturers, on the Beast with LEDBlinky. Arzoo is the man to talk to about LEDBlinky.

I have three PACLED64 controllers, and for LEDBlinky to see each LED, I would think it would have to be only one light on each port. Or at least multiple lights on each port. To combat the joystick lighting up per game, I routered out a small well on the underside of my CP, glued the LED in facing into the well where the shaft of the stick goes, and applied reflective chrome tape on the inside of the well. You only need one LED and it lights up the whole well. Obviously you'd need a clear dust washer to even see the light in the well.

As far as LEDBlinky seeing each controller, LB works on keystroke or controller codes. In my setup, I have set the LED for the Joystick to be JOYSTICK_1_UP, and when I set the game, I just use that input as my LED, just like you would KeyA, B, C, etc. Hope that makes sense.
