How i do to blink a led with the gpio port.

hi

im cuban and my internet conexion sucks (6kb/s speed) but im trying to finish a project but im stuck.

im triying to do that a withe led strip (12v) blink like a binary counter, its 6 seccion of these strip, so i use the my_first_fpga project for altera and change the pin assigment from the led pins to the gpio port pins i need, but dosent work. i tried to search some documentation but dosent help.

i already mount the mosfets and when its not running the program the DE0 NANO CYCLONE IV give the 1.3 volts i need, but when the program run give only 0.6 and do nothing.

please i be very gratefull if someone helpme.

i know its a basic question but i need to implement these for a thesis project and i just cant do it.

    Are you sure the IO can deliver the current needed to "switch" the FETs?
