arduino Mega / pin 28 / Reset

Hello,

I use pin 28 on an arduino Mega to control a transistor (aside of other I/O)
I realised the board reset when state of pin 28 changes
I tried another pin, and no problem anymore
someone knows why?

Show us a good schematic of your circuit.
Show us a good image of your ‘actual’ wiring.
Give links to components.
Posting images:

reset happens even when nothing connected on this pin

Maybe the MEGA schematic will give you a clue
