How do I start my Arduino going?
Hey guys I just got my Arduino Uno and I'm not exactly sure how to power it up using the jack. I now know that I can run it off of the USB cable but how do I hook a battery to it? I've heard that your supposed to use 5 volts, but I don't see how I can get 5 volts. I only use AA and 3v and 9v batteries. So, also, since it can run off a USB port, I'm assuming I can use my phone charger to hook up the USB to it? Isn't it all 5.1 v? Well, please help me out and tell me if how many volts mA the board needs, which is too much and which is to low.
