Hi
I'm new to this and really like theIR library .
I wondered if you could answer a question?
When I play an IR code in Irecord on Arduino uno , I get 5ma going to the Led ( with no resistor in line)
However when I play a code with Irsend demo I get 10 ma at the led with no resistor?
I know the pins should be able to give out around 40ma with digitalWrite HIGH. But I can only assume current goes down as pwm frequency goes up?
Sorry in advance if this is a stupid question , but I can't find any info on it.
Many thanks Paul
