HI,
I just want to make sure I get a response, and understand, not double posting,
I put a question in the development section for the frequencie librarie, but Illl refrase it here to know I get it.. (sorry im still learning)
so, I have 2 arduinos,
one with a blink the other with the freq counter,
when I connect the pin doing the blink and gnd to the other arduino I get strange behavior in one of the arduinos (do I need some protection? to avoid short circuit??)
Is the signal from the blink, big enough to set the freq counter?
thank you
