Hello! I have been having a problem settiing up some LED outputs. When I test them one at a time in the config wizard, I can make some of them light up, but some of them do no. Checking the voltages I can see 3.5v on the ones that are working but the ones that are not I only see 2v, which is why I think they are not working. Any suggestions?

which Pins do you use for the ones that work and the ones that don't work?

Pins 36 & 28 are giving me the low voltage. Pins 27, 29, and 30 are all working

That should be 26, not 36

That's strange... have you configured only LED Outputs so far? Normally all pins should do well.

If you want to make sure, that it is related to MobiFlight you could use the blink example sketch that comes with the Arduino IDE. Change the code to use the appropriate pins and then upload the sketch. If it works now, then there is a problem with MobiFlight. Otherwise it would be the board itself.

Good idea! I did that and found a short in my wiring (I had both LEDs blink when I tried the blink sketch). Not sure why they both didnt light up with mobiflight if they did with the blink sketch. Thanks for the suggestion.

I have them working correctly now, but I noticed there was a slider in the config for brightness that is greyed out? Is that not implemented yet?

That's not implemented yet for MobiFlight but would work for Aracze.
