Need help supplying more amps than my arduino can.
I am working on my first project that applies arduino to the real world and needed to know how to supply more current than the arduino can output to several components. There will be 4-6 of these components, each one needing 5V at 0.6 Amps. I need to know whether or not I should use a step up regulator or a transistor or other component to power the device. I will have an external power supply, most likely 1 or 2 lipo batteries to power the whole thing too.
