diogo_zanardini:
I use the all pins to light up this thing:
but the pin 13 the brightness is smaller than the rest...
my guess is because the internal led lights up together, dividing the current, so I want to know if I can disable the internal led in this case
void setup()
{
pinMode(13, OUTPUT);
digitalWrite(13 HIGH);
}
If you dont want the LED connected to pin 13 to activate when pin 13 is used, then you need to disconnect the pin13 LED or its series resistor.
