Hello all,

I'm new with you and happy to be here

My little first board working very well when FS is launched. All is perfect, light are on when they must and Off when their must also....

I've a simple question :
I've connected 2 leds, each on different ports. Very simple.
I just connect my Arduino on the USB cable, and no software started excepting MobiFlight.
My Leds are light !!!!

It is possible to have light OFF by default and when FS launched, my leds fallow the Aircraft functions ?

Thanks fo your help
Cheers
Stef

You must have connected them incorrectly.

An LED can turn on when the pin is set to HIGH. So your pin has to be connected to the anode and the cathode to the GND pin.
If you do it the other way around: LED anode to 5VCC on board, and the cathode to the pin, then you end up with your behavior.

Have a great day!
