I currently have my arduino mega 2560 hooked up to a adaruit motor shield. I have a 9 volt battery connected to the adafruit motor shield and it is powering both the shield and arduino. is the voltage going to the arduino at 9v or does the arduino have a built in voltage regulator? what is the voltage coming out of the IO pins on the arduino? thank you so much!!!
