I am planning to build an rc car based on arduino uno. I will use 3S 11.1 V Li-po to power whole circuitry. So my question is;
First, can arduino be powered directly with 11.1V from its Vin pin? Would it be a problem or not? If it is OK, then no need to answer the bold part below.
If it is not, then one solution comes to my mind is to use a voltage regulator which will convert 11.1 V to 5 V. But while choosing a regulator, I saw that max output current is one of the important specs. So what is the minimum amount of current needed to run Arduino UNO?
