nano v3.0 voltage question

hi, i've got a new nano v3, when i pull one pin high it only gies me 0.5 olt not enough to trigger my transistor. is the board broken?? when i got it the pins where already damaged. thx

when i don't pull it low full high i can barely light a led without a risistor

sorry fixid it

hope you might have forgot to set pinMode to OUTPUT?
