Need help supplying more amps than my arduino can. Answered

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.

A transistor is exactly what you need. There are a multitude of different types available (check Digikey or Mouser) and are typically rated by power handling capability (watts) or current/voltage. It is better to use a transistor that is rated higher than what you expect to switch to prevent overheating and possibly damaging it

Thanks, that is what I was thinking would be best, just felt as though a second opinion wouldn't be a bad idea.
