The positive rail doesnt connect to anything. This wiring diagram is not accurate.

Sorry for delay in response Yes you can add as much as led you want depending on your board and you need to modify the code if adjoining to other pin

Sorry for delay in response Actually that time I was short of LED and my main goal was to explain the concept so I added blue led rather than yellow

if you are using standard LEDs (1.8V - 2V), you should probably add some sort of series resistance to drop the remaining ~3V. no sense in burning out your LEDs.

That's absolutely true. But this led can hold upto 9V So in this led I dont require that
