Hi,
My arduino uno digital output pins doesn't supply more than 64.00 micro-amps, shouldn't it supply up to 40
milliamps?!
I'm frustrated and need some help please !
Thank you ..

Did you remember to turn on the pin's output drivers?
pinMode(pin, OUTPUT);
No i didn't
Thank you sir, that helped
But how did it work in the first place?! as i can remember the pins are inputs by default .. !
The output register doubles as enables for the input pull-up resistors. When you write a 1 to an input pin it turns on the pull-up resistor and that would source a small quantity of current.
Thanks again sir, my regards ..
