Help! I've been working on a robot, and I need it done very soon. I am using an Arduino Uno with a motor shield, and it works fine when connected to my computer, but when i plug in the 9v battery, and switch it to VIC, nothing happens. There are a series of clicks, however.

Those small 9 volt batteries do not have enough current capacity to drive your motor. Try building a battery pack out of AA batteries, say 6 of them is series, that should work much better.

Would it still safely work with an Arduino if there were 6 AAs?

Why wouldn't it be safe?

well would it be too much voltage for it to handle?
