1. What voltage(s) should you provide when you power the Arduino through the barrel jack? How much current can be made available to the Arduino through this port? Does this port have any protection on it?
2. When you are powering the board using the barrel jack, what does the Vin pin do?
3. When you are powering the board using one of the ports mentioned above, how much current can you draw from the 5V pin? What about the 3.3V pin? What about a regular I/O (digital or analog) pin?
4. What voltage(s) should you provide when you power the Arduino through the Vin pin? How much current can be made available to the Arduino through this pin? Does this port have any protection on it?
5. What voltage(s) should you provide when you power the Arduino through the 5V pin? How much current can be made available to the Arduino through this pin? Does this port have any protection on it?
6. How much power does a normal 9V battery contain? How long could you run an Arduino board with it?
