In the datasheet, I see that the maximum current output of a pin is 40mA. I have connected in series an LED with Vf = 1.2Volts and a 100 Ohm resistor so I draw 38mA which almost the max value. If I use 40kHz pulse with 50% cycle could I lower my resistor value to half or to a certain point and not burn my Arduino?
I didn't find the right solution from the Internet.
