Hello all,

I'm new here,  but hoping to get a bit of help. I built an arduinoboy tonight, and everything seemed to go fine. Unfortunately, I do not have a link cable to test with, so I'm unable to test with an actual gameboy (pretty stupid right?) I was able to get things working from an aesthetic level (when switched on, LEDs light up, although 2 do not. Not sure if that is a bad LED issue or not.) The problem is that when I connect my keyboard to the midi in jack....nothing happens. No lights. Is this due to the gameboy not being connected? I'm really hoping it is, because the midi is wired up correctly...

Thanks,

Christian

Normally you'd power the aboy from the link port, if not link cable is attached, how are you powering it?

It's being powered by a 9v, since I don't believe the link cable my roommate has has the power pin (although I'll probably do the mod at some point.) But yes, a 9v battery at the moment with a voltage regulator

I dont have the ability to test on mine if you need the dmg connected to see the midi i/o.. but i guess thats the next step to test.

Yea, it is...was just hoping somebody knew off the top of their head, waiting to get the link cable to know if it is working or not may kill me.

I dont know for keyboard, but on midi clock the lights will light up no matter if a GB is connected.. so i guess the same goes for keyboard!
I know many people who think they wired everything correct, be careful on the schematic, some things arent 100 % clear!
i never had 2 broken LED's at once, this is very unlikely if 2 out of 6 dont work. I guess you have something wired up wrong.
Double check the wiring and after that, repeat the process big_smile

Interestingly, I checked out the LEDs with a multimeter and both were dead! Got a much bigger problem now, I'm gunna post a new topic sad

Any ideas? Gameboy is wired to it and providing power, i've tried reversing the wires for the midi, and still nothing...I'm pretty sure the rest is wired right, it boots up correctly and I'm using a pcb...

Should also mention that the midi cable is fine, tested it with 2 keyboards
