Can we use an Arduino for controlling LED's

[trumpthero786]

You can totally do that. We did that last year and plan on doing it again this year.

Some of my team members have said that LED strips aren't allowed this year, however I can't find the specific rule stating this. R9 could apply:

C. Any devices or decorations specifically intended to jam or interfere
with the remote sensing capabilities of another ROBOT, including
vision systems, acoustic range finders, sonars, infrared proximity
detectors, etc. (e.g. including imagery on your ROBOT that, to a
reasonably astute observer, mimics the retro-reflective features of the
TOWER described in Section 2.3.1.3 TOWER)

LEDs are still perfectly legal, and fall under the custom circuit rules. Make sure to read them all carefully.
