hi, i'm new with arduino. I've just got my board, connected a led to pin 12 with a 1kohm resistor and loaded a code to turn on the led. But when the program starts the led starts to blink all the time. Is this normal?
if i connect the led to pin 13 and turn it on, the on board led turns on and stays like that, but the led connected to the pin blinks. i don't know if this is normal. how do u do to have a non-blinking led?
