Arduino kaç mili amper (ma) çekecek,
Pil kaç mah

9v piller 10ma akımda 110 saat çalışıyormuş vs.
While we're at it: How long will the battery last? How long is "a while"? A typical 9v alkaline (non-rechargeable) battery will give you about 56 hours of operation if you put it in a circuit where the resistance means that the current which flows is 10mA. Or, you could have about 112 hours of operation at 5mA. Again, there are limits. I doubt you will get 1 hour of operation at 56 times 10mA. This property of the battery is called it's capacity
