mem, thank again, it looks a lot easier this way, so i can use any analog pin as an output(digital) as well, ok thats nice....
To test this skecth i´ll be using windows Xp hyper terminal and send characters over the arduino to control servos, but in the future i´ll be making another pcb to read any ppm frame (futaba or Multiplex) from the radio trainer port, so i would like to ask you what do you recommend as the best method to read it and send the several servo "pulse width" as characters to the ardu decoder board.
I´ve been searching for info about this for a while and it looks to me that it will take some time till i find the best solution.
thanks
