Re: Using the TI LaunchPad from your KoP

What are people thinking of using to provide power to these devices? Are you considering a second power plug (like a wall wart) to supply the additional current?

So, the current plan is to actually control an addressable string of LEDs with an Arduino. The Arduino will be interfaced to a couple of the Digital outputs on the LaunchPad to know what pattern to display. The Arduino and the LEDs will get their power from a LiPo battery through a UBEC. That way, if the LiPo is not there, or too low, the LEDs just won't work, but the rest of the DS will function normally.
