If he wants to build and run circuits without resistors on his LEDs, by all means, LET HIM.
If he wants to build circuits with the exact voltage needed for each LED being used, LET HIM.
Someone please tell me why on earth must we explain something that everyone knows and understand when clearly all he wants to do is pick a fight.
Because he is answering questions of people asking about how to use LED's, telling them they don't need to use resistors.
They might just need a transistor (that does need a resistor in the base) and PWM.
show me where i tell people "don't need to use resistors"
all lies, this was about a specific question which i now have answers to.. just because you don't read all of my posts and just comment on what you feel like don't get on your high horse and spread lies...
An LED UNDER CONTROLLED CONDITIONS (Controlled being the key word)
does NOT need a resistor....
Oh and yes... I'm very VERY much calm as i type this thank you very much... I know you like to jump conclusions.
