Each pin can provide sink up to 40 ma max. I advise you to download it and open the pcb and schematic using eagle cad while you are reading this article. In this experiment 5v is adopted so the minimum resistance of the current limiting resistor should be 5 v to 1 8 v 20 160 ohm.
The operating voltage of the led is 1 8v and the operating current is 10ma 20ma.
Arduino disclaims all other warranties express or implied arduino may make changes to specifications and product descriptions at any time without notice. Just connect it to a laptop or computer having a usb cable or power it with a ac to dc. In the arduino uno pins 3 5 6 9 10 11 have pwm capability. Pin 13 of the arduino uno is connected to the built in led.
