What is the supply (MAh) of a 9 volt battery? The draw of an arduino in genral use? And a standerd led?
I was building a fancy arduino supply and need to know the draw from these three things. Can anyone tell me. What a arduino duemilanove draws (in standerd use) (MAh)? What a 9 volt battery supplys (MAh)? What a adverage led uses (Mah)
