can an aurduino uno run on a 7.2 volt battery? Answered
i am working on a project using an aurduino and a relay shield and i want to power it with a 7.2 volt battery like the kind you find in rc cars. i don't know if it will draw too much current and fry the aurduino because that wouldn't be good. is there some way to regulate current without dropping voltage? i have been doing some research on google and found people that have been doing this with an aurduino mega but that has a built in voltage regulator and i kinda fried mine a while back in the project and now i am using a resistor diode pair to keep a solid 5 volts but that isn't enough for the relay shield.
thanks a lot
