.... for motor you need transistor.
Hi, I'm begginer in electronic and I connected a dc motor and a led to digital pins in PWM mode of the arduino board without a resistance (I connceted them directly), I want to know if do that is damaging for the arduino board or only is bad for the Led or the motor that use 5v, for that I think that the motor don't need a resistance. It's true?Thanks.
